-Gradle is used for all C++ and Java code, and NPM is used for the web UI. Instructions to compile PhotonVision yourself can be found [in our docs](https://docs.photonvision.org/en/latest/docs/contributing/building-photon.html#compiling-instructions).

 You can run one of the many built in examples straight from the command line, too! They contain a fully featured robot project, and some include simulation support. The projects can be found inside the [`photonlib-java-examples`](photonlib-java-examples) and [`photonlib-cpp-examples`](photonlib-cpp-examples) subdirectories, respectively. Instructions for running these examples directly from the repo are found [in the docs](https://docs.photonvision.org/en/latest/docs/contributing/building-photon.html#running-examples).

 ## Before Competition
 
 - Ensure you have spares of the relevant electronics if you can afford it (switch, coprocessor, cameras, etc.).
-- Download the latest release .jar onto your computer and update your Pi if necessary (only update if the release is labeled "critical" or similar, we do not recommend updating right before an event in case there are unforeseen bugs).
-- Test out PhotonVision at your home setup.
-- Ensure that you have set up SmartDashboard / Shuffleboard to view your camera streams during matches.
-- Follow all the recommendations under the Networking section in installation (network switch and static IP).
-- Use high quality ethernet cables that have been rigorously tested.
-- Set up port forwarding using the guide in the Networking section in installation.
+- Stay on the latest version of PhotonVision until you have tested your full robot system to be functional.
+- Some time before the competition, lock down the version you are using and do not upgrade unless you encounter a critical bug.
+- Have a copy of the installation image for the version you are using on your programming laptop, in case re-imaging (without internet) is needed.
+- Extensively test at your home setup. Practice tuning from scratch under different lighting conditions.
+- Confirm you have followed all the recommendations under the {ref}`Networking<docs/quick-start/networking:Networking>` documentation (network switch and static IP).
+- Only use high quality ethernet cables that have been rigorously tested.
+
+## Camera Streaming
+- All camera streams are published under the NetworkTables table `CameraPublisher`.
+- The only subtable under `CameraPublisher` that will work for viewing a driver mode camera stream is the one that contains `Output` in the name.
+- To view a camera stream in a dashboard, drag the correct subtable from the NetworkTables tree into your dashboard.
+- Use the latest driver dashboard recommended by [WPILib](https://docs.wpilib.org/en/stable/docs/software/dashboards/dashboard-intro.html) on your driver station laptop.
 
 ## During the Competition
 
-- Make sure you take advantage of the field calibration time given at the start of the event:
-    - Bring your robot to the field at the allotted time.
-    - Turn on your robot and pull up the dashboard on your driver station.
-    - Point your robot at the AprilTags(s) and ensure you get a consistent tracking (you hold one AprilTag consistently, the ceiling lights aren't detected, etc.).
-    - If you have problems with your pipeline, go to the pipeline tuning section and retune the pipeline using the guide there.
-    - Move the robot close, far, angled, and around the field to ensure no extra AprilTags are found.
-    - Go to a practice match to ensure everything is working correctly.
+- Use the field calibration time given at the start of the event:
+  - Bring your robot to the field at the allotted time.
+  - Make sure the field has match-accurate lighting conditions active.
+  - Turn on your robot and pull up the dashboard on your driver station.
+  - Point your robot at the targets and ensure you get a consistent tracking (you hold one targets consistently, the ceiling lights aren't detected, etc.).
+  - If you have problems with your pipeline, retune the pipeline following the {ref}`camera tuning <docs/pipelines/input:Camera Tuning / Input>` documentation.
+  - Move the robot close, far, angled, and around the field to ensure no extra targets are found.
+  - Monitor camera feeds during a practice match to ensure everything is working correctly.
 - After field calibration, use the "Export Settings" button in the "Settings" page to create a backup.
-    - Do this for each coprocessor on your robot that runs PhotonVision, and name your exports with meaningful names.
-    - This will contain camera information/calibration, pipeline information, network settings, etc.
-    - In the event of software/hardware failures (IE lost SD Card, broken device), you can then use the "Import Settings" button and select "All Settings" to restore your settings.
-    - This effectively works as a snapshot of your PhotonVision data that can be restored at any point.
-- Before every match, check the ethernet connection going into your coprocessor and that it is seated fully.
-- Ensure that exposure is as low as possible and that you don't have the dashboard up when you don't need it to reduce bandwidth.

 # Filesystem Directory
 
-PhotonVision stores and loads settings in the {code}`photonvision_config` directory, in the same folder as the PhotonVision JAR is stored. On the Pi image as well as the Gloworm, this is in the {code}`/opt/photonvision` directory.

+
+The [Romi](https://docs.wpilib.org/en/latest/docs/romi-robot/index.html) is a small robot that can be controlled with the WPILib software. The main controller is a Raspberry Pi that must be imaged with [WPILibPi](https://docs.wpilib.org/en/latest/docs/romi-robot/imaging-romi.html) .
+
+## Installation
+
+The WPILibPi image includes FRCVision, which reserves USB cameras; to use PhotonVision, we need to edit the `/home/pi/runCamera` script to disable it. First we will need to make the file system writeable; the easiest way to do this is to go to `10.0.0.2` and choose "Writable" at the top.
+
+SSH into the Raspberry Pi (using Windows command line, or a tool like [Putty](https://www.chiark.greenend.org.uk/~sgtatham/putty/) ) at the Romi's default address `10.0.0.2`. The default user is `pi`, and the password is `raspberry`.

+:::.. Follow the process for installing PhotonVision on {ref}`"Other Debian-Based Co-Processor Installation" <docs/advanced-installation/sw_install/other-coprocessors:Other Debian-Based Co-Processor Installation>`. As it mentions, this will require an internet connection so connecting the Raspberry Pi to an internet-connected router via an Ethernet cable will be the easiest solution. The pi must remain writable while you are following these steps!
+
+:::..Temporary instructions explaining how to install the older version of PhotonVision on a Romi. Remove when no longer needed.
+:::{attention}
+The version of WPILibPi for the Romi is 2023.2.1, which is not compatible with the current version of PhotonVision. **If you are using WPILibPi 2023.2.1 on your Romi, you must install PhotonVision v2023.4.2 or earlier!**
+
+To install a compatible version of PhotonVision, enter these commands in the SSH terminal connected to the Raspberry Pi. This will download and run the install script, which will install PhotonVision on your Raspberry Pi and configure it to run at startup.
+
+```bash
+$ wget https://git.io/JJrEP -O install.sh
+$ sudo chmod +x install.sh
+$ sudo ./install.sh -v v2023.4.2
+```

+:::
+:::..End of temporary instructions.
+
+Next, from the SSH terminal, run `sudo nano /home/pi/runCamera` then arrow down to the start of the exec line and press "Enter" to add a new line. Then add `#` before the exec command to comment it out. Then, arrow up to the new line and type `sleep 10000`. Hit "Ctrl + O" and then "Enter" to save the file. Finally press "Ctrl + X" to exit nano. Now, reboot the Romi by typing `sudo reboot now`.
+
+```{image} images/nano.png

+
+After the Romi reboots, you should be able to open the PhotonVision UI at: [`http://10.0.0.2:5800/`](http://10.0.0.2:5800/). From here, you can adjust settings and configure {ref}`Pipelines <docs/pipelines/index:Pipelines>`.

 ### Target Family
 
-Target families are defined by two numbers (before and after the h). The first number is the number of bits the tag is able to encode (which means more tags are available in the respective family) and the second is the hamming distance. Hamming distance describes the ability for error correction while identifying tag ids. A high hamming distance generally means that it will be easier for a tag to be identified even if there are errors. However, as hamming distance increases, the number of available tags decreases. The 2024 FRC game will be using 36h11 tags, which can be found [here](https://github.com/AprilRobotics/apriltag-imgs/tree/master/tag36h11).

 ## Ambiguity
 
-Translating from 2D to 3D using data from the calibration and the four tag corners can lead to "pose ambiguity", where it appears that the AprilTag pose is flipping between two different poses. You can read more about this issue `here. <https://docs.wpilib.org/en/stable/docs/software/vision-processing/apriltag/apriltag-intro.html#d-to-3d-ambiguity>` Ambiguity is calculated as the ratio of reprojection errors between two pose solutions (if they exist), where reprojection error is the error corresponding to the image distance between where the apriltag's corners are detected vs where we expect to see them based on the tag's estimated camera relative pose.

+
+## Description
+This benchmark compares the performance of four object detection models: YOLOv5, YOLOv5u, YOLOv8, and YOLOv11 on the [COCO 2017 Validation Set](http://images.cocodataset.org/zips/val2017.zip). The main purpose is to assess and compare the inference speed and detection accuracy of these models when deployed on the Orange Pi devices using the RKNN framework and int8 quantization.
+
+## Methodology
+- **Dataset**: [COCO 2017 Validation Set](http://images.cocodataset.org/zips/val2017.zip) (5,000 images)
+
+- **Platform**: Orange Pi 5 with RK3588
+
+- **Quantization**: int8 using 20 randomly selected images from the validation set
+
+- **Framework**: RKNN Toolkit 2
+
+## Operator-Level Benchmark Results
+
+The following tables break down the average CPU time, NPU time, and total execution time (in microseconds) for each operator used by the models. Each value represents the mean ± standard deviation across 5,000 inferences.

+## Conclusion
+
+The benchmark reveals a clear performance trade-off between inference time and detection accuracy:
+
+- **YOLOv5** is the fastest model with the lowest total inference time, making it well-suited for situations where speed is more important than high detection precision.
+
+- **YOLOv11** achieves the highest accuracy (mAP) across all IoU thresholds but comes with the longest inference time, which may limit its use in real-time applications.
+
+- **YOLOv8** offers a strong balance between speed and accuracy, making it a practical choice when both factors matter.
+
+- **YOLOv5u** improves accuracy compared to YOLOv5 but falls behind YOLOv8 in both speed and detection quality.
+
+When choosing a model for edge devices like the Orange Pi 5, it’s important to weigh how much latency your system can tolerate versus how much accuracy you need. A faster model may give quicker results, while a more accurate one may offer better detection reliability, but at the cost of speed.

-To calibrate a camera, images of a Charuco board (or chessboard) are taken. By comparing where the grid corners should be in object space (for example, a corner once every inch in an 8x6 grid) with where they appear in the camera image, we can find a least-squares estimate for intrinsic camera properties like focal lengths, center point, and distortion coefficients.

By comparing where the grid corners should be in object space (for example, a corner once every inch in an 8x6 grid) with where they appear in the camera image, we can find a least-squares estimate for intrinsic camera properties like focal lengths, center point, and distortion coefficients. For more on camera calibration, please review the [OpenCV documentation](https://docs.opencv.org/4.x/dc/dbb/tutorial_py_calibration.html).

+:::{warning}
+Arducam Pivariety cameras are **incompatible** with PhotonVision as they require a custom camera library not compatible with PhotonVision.
+:::
+
+Arducam cameras are supported for setups with multiple devices. This is possible because Arducam provides software that allows you to assign truly different device names to each camera. This feature is particularly useful in complex setups where multiple cameras are used simultaneously.
+
+## Setting Up Arducam Cameras
+
+1. **Download Arducam Software**: [Download and install the Arducam software from their official website.](https://docs.arducam.com/UVC-Camera/Serial-Number-Tool-Guide/)
+
+2. **Assign Device Names**: Use the Arducam software and Arducam [documentation](https://docs.arducam.com/UVC-Camera/Serial-Number-Tool-Guide/) to give each camera a unique device name. This will help in distinguishing between multiple cameras in your setup.
+
+## Steps to Configure in PhotonVision
+
+1. **Open PhotonVision Settings**: Navigate to the cameras page in PhotonVision.
+
+2. **Select Camera Model**: Select the proper camera. Use the Arducam model selector to specify the model of each Arducam camera connected to your system.
+
+3. **Save Settings**: Ensure that you save the settings after selecting the appropriate camera model for each device.

+By default, tests are run with UI disabled so they are not obtrusive during a build. All tests should be useful when the UI is disabled. However, if a particular test would benefit from having UI access (i.e. for debugging info), the UI can be enabled by passing the `enableTestUi` project property to Gradle. This will run all tests by default, but the Gradle `--tests` option can be used to [filter for specific tests](https://docs.gradle.org/current/userguide/java_testing.html#test_filtering).

+### Reactivate a CameraConfig
+
+When a new camera (ie, one we can't match by-path to a deserialized CameraConfiguration) is activated, we'll create and spin up a new Vision Module for it.

+# Camera Matching Requirements
+
+## Definitions
+- VALID USB PATH: a path in the form `/dev/v4l/by-path/[UUID]`
+- VIDEO DEVICE PATH: a CSCore-provided identifier derived from the V4L path `/dev/video[N]` on Linux, or an opaque string on Windows
+- UNIQUE NAME: an identifier that is unique within the set of all deserialized CameraConfigurations and unmatched USB cameras
+  - I don't love this, it means that a USB camera matched to a VisionModule will share a UNIQUE NAME, right?
+- DESERIALIZED CAMERA CONFIGURATIONS: The set of camera configurations loaded from disk and provided to the VisionSourceManager. This configuration data structure includes the UNIQUE NAME
+- CURRENTLY ACTIVE CAMERAS: The set of VisionModules currently active and processing vision data, and associated metadata
+
+## Startup:
+
+- GIVEN An empty set of deserialized Camera Configurations
+<br>WHEN PhotonVision starts
+<br>THEN no VisionModules will be started
+
+- GIVEN A valid set of deserialized Camera Configurations
+<br>WHEN PhotonVision starts
+<br>THEN VisionModules will be started FOR EACH un-DISABLED config
+
+- GIVEN A valid set of deserialized Camera Configurations
+<br>WHEN PhotonVision starts
+<br>THEN VisionModules will NOT be started FOR EACH DISABLED config
+
+- GIVEN A CameraConfiguration with a VALID USB PATH
+<br>WHEN a VisionModule is created
+<br>THEN The VisionModule shall open the camera using the USB path
+
+- GIVEN A CameraConfiguration without a valid USB path
+<br>WHEN a VisionModule is created
+<br>THEN The VisionModule shall open the camera using the VIDEO DEVICE PATH
+
+## Camera (re)enumeration:
+
+- GIVEN a NEW USB CAMERA is available for enumeration
+<br>WHEN a USB camera is discovered by VisionSourceManager
+<br>AND the USB camera's VIDEO DEVICE PATH is not in the set of DESERIALIZED CAMERA CONFIGURATIONS
+<br>THEN a UNIQUE NAME will be assigned to the camera info
+
+- GIVEN a NEW USB CAMERA is available for enumeration
+<br>WHEN a USB camera is discovered by VisionSourceManager
+<br>AND the USB camera's VIDEO DEVICE PATH is in the set of DESERIALIZED CAMERA CONFIGURATIONS
+<br>THEN a UNIQUE NAME equal to the matching DESERIALIZED CAMERA CONFIGURATION will be assigned to the camera info
+  - This is a weird case. How -should- we handle this? see above
+
+## Creating from a new camera
+
+- Given: A UNIQUE NAME from a NEW USB CAMERA
+<br>WHEN I request a new VisionModule is created for this NEW USB CAMERA

+# Latency Characterization
+
+
+## A primer on time
+
+Especially starting around 2022 with AprilTags making localization easier, providing a way to know when a camera image was captured at became more important for localization.
+Since the [creation of USBFrameProvider](https://github.com/PhotonVision/photonvision/commit/f92bf670ded52b59a00352a4a49c277f01bae305), we used the time [provided by CSCore](https://github.wpilib.org/allwpilib/docs/release/java/edu/wpi/first/cscore/CvSink.html#grabFrame(org.opencv.core.Mat)) to tell when a camera image was captured at, but just keeping track of "CSCore told us frame N was captured 104.21s after the Raspberry Pi turned on" isn't very helpful. We can decompose this into asking:
+
+- At what time was a particular image captured at, in the coprocessor's timebase?
+- How do I convert a time in a coprocessor's timebase into the RoboRIO's timebase, so I can integrate the measurement with my other sensor measurements (like encoders)?
+
+The first one seems easy - CSCore tells us the time, so just keep track of that? Should be easy. For the second, translating this time, as measured by the coprocessor's clock, into a timebase also used by user code on the RoboRIO, is actually a [fairly hard problem](time-sync.md) that involved reinventing [PTP](https://en.wikipedia.org/wiki/PTP).
+
+And on latency vs timestamps - PhotonVision has exposed a magic "latency" number since forever, but latency (as in, the time from image capture to acting on data) can be useful for benchmarking code, but robots actually want to answer "what time was this image from, relative to "?
+
+
+## CSCore's Frame Time
+
+WPILib's CSCore is a platform-agnostic wrapper around Windows, Linux, and MacOS camera APIs. On Linux, CSCore uses [Video4Linux](https://en.wikipedia.org/wiki/Video4Linux) to access USB Video Class (UVC) devices like webcams, as well as CSI cameras on some platforms. At a high level, CSCore's [Linux USB Camera driver](https://github.com/wpilibsuite/allwpilib/blob/17a03514bad6de195639634b3d57d5ac411d601e/cscore/src/main/native/linux/UsbCameraImpl.cpp) works by:
+
+- Opening a camera with `open`
+- Creating and `mmap`ing a handful of buffers V4L will fill with frame data into program memory
+- Asking V4L to start streaming
+- While the camera is running:
+  - Wait for new frames
+  - Dequeue one buffer
+  - Call `SourceImpl::PutFrame`, which will copy the image out and convert as needed
+  - Return the buffer to V4L to fill again
+
+Prior to https://github.com/wpilibsuite/allwpilib/pull/7609, CSCore used the [time it dequeued the buffer at](https://github.com/wpilibsuite/allwpilib/blob/17a03514bad6de195639634b3d57d5ac411d601e/cscore/src/main/native/linux/UsbCameraImpl.cpp#L559) as the image capture time. But this doesn't account for exposure time or latency introduced by the camera + USB stack + Linux itself.
+
+V4L does expose (with some [very heavy caveats](https://github.com/torvalds/linux/blob/fc033cf25e612e840e545f8d5ad2edd6ba613ed5/drivers/media/usb/uvc/uvc_video.c#L600) for some troublesome cameras) its best guess at the time an image was captured at via [buffer flags](https://www.kernel.org/doc/html/v4.9/media/uapi/v4l/buffer.html#buffer-flags). In my testing, all my cameras were able to provide timestamps with both these flags set:
+- `V4L2_BUF_FLAG_TIMESTAMP_MONOTONIC`: The buffer timestamp has been taken from the CLOCK_MONOTONIC clock [...] accessible via `clock_gettime()`.
+- `V4L2_BUF_FLAG_TSTAMP_SRC_SOE`: Start Of Exposure. The buffer timestamp has been taken when the exposure of the frame has begun.
+
+I'm sure that we'll find a camera that doesn't play nice, because we can't have nice things :). But until then, using this timestamp gets us a free accuracy bump.
+
+Other things to note: This gets us an estimate at when the camera *started* collecting photons. The camera's sensor will remain collecting light for up to the total integration time, plus readout time for rolling shutter cameras.
+
+## Latency Testing
+
+Here, I've got a RoboRIO with an LED, an Orange Pi 5, and a network switch on a test bench. The LED is assumed to turn on basically instantly once we apply current, and based on DMA testing, the total time to switch a digital output on is on the order of 10uS. The RoboRIO is running a TimeSync Server, and the Orange Pi is running a TimeSync Client.

+            }

+            e.printStackTrace();
+        }
+    }
+}
+```
+</details>
+
+I've decreased camera exposure as much as possible (so we know with reasonable confidence that the image was collected right at the start of the exposure time reported by V4L), but we only get back new images at 60fps. So we don't know when between frame N and N+1 the LED turned on - just that sometime between now and 1/60th of a second a go, the LED turned on.
+
+The test coprocessor was an Orange Pi 5 running a PhotonVision 2025 (Ubuntu 24.04 based) image, with an ArduCam OV9782 at 1280x800, 60fps, MJPG running a reflective pipeline.
+
+
+### Test Results
+
+The videos above show the difference between when the RoboRIO turned the LED on and when PhotonVision first seeing a camera frame with the LED on, what I've called error and plotted in yellow with units of seconds. This error decreases when I use the frame time reported by V4L from a mean delta of 26 ms to a mean delta of 11 ms (below the maximum temporal resolution of my camera).

+Old CSCore:

+CSCore using V4L frame time:
+```{raw} html
+<video width="85%" controls>
+    <source src="../../../_static/assets/latency-tests/ov9782_1280x720x60xMJPG_new.mp4" type="video/mp4">
+    Your browser does not support the video tag.
+</video>
+```
+
+With the camera capturing at 60fps, the time between successive frames is only ~16.7 ms, so I don't expect to be able to resolve anything smaller. Given sufficient time and with perfect latency compensation, and with more noise in the robot program to make sure we vary LED toggle times, I'd expect the error to converge to ~half the interval between frames - so being within this frame interval with CSCore updates is a very good sign.
+
+### Future Work
+
+This test also makes no effort to isolate error from time synchronization from error introduced by frame time measurement - we're just interested in overall error. Future work could investigate the latency contribution
