  • Rename Freeze to Toggle
  • Add Freeze, If, SwitchBoolean, SwitchNumber, and NOP nodes

Tweaks

• Uses Path instead of PosixPath for cross-platform compatibility
• Restructured the CameraServer module
• Removed videoio's hard dependency on upgraded-engineer (h.264)
• Made FindCorners more robust for contours with >4 corners
• For FPS calculation, uses average of last few seconds rather than entire duration of pipeline
• Upgraded dependencies to latest versions
• Normalized CSS
• Flushes NetworkTables each update cycle
• Uses sane defaults for compression and fps for MJPEG streams
• Automatically cancels any nodes dependent upon nodes which have errored
• Moved H.264 to port 554
• Disabled auto-exposure

Bug Fixes

• Fixed AbsoluteDifferenceHSV output
• Fixed NetworkTables for teams with less than 4 digits
• Added commas to Cache-Control header
• Ensures rusty-engine quits on OpenSight exit
• Ensures SolvePNP distance accuracy
• Added MatBW -> Mat auto conversions where are required
• Fixed GPIO LED and PWMLED
• Allow importing of pipelines with GetNT nodes which have nonexistent paths
• Allow importing of pipelines with nonexistent cameras
• Fixed output naming error of BooleanSwitch node

Packages

• Separate dependencies into Depends, Recommends, and Suggests (allows installing OpenSight without forcefully installing every optional dependency)
• Added imutils to dependencies

Raspberry Pi Image

• Merged latest upstream raspbian changes
• Disable WiFi by default
• Install OpenSight package Suggests dependencies

Post-Post-Kickoff Update

OpenSight

• Debug verbosity has been restored back to DEBUG level.

• Network settings now load properly.

• Color balance (red/blue) node has been added.

• Contour area node has been added.

• H.264 CameraServer now correctly uses port 554.

• SolvePNP Module

  • Added SolvePNP, Position2D, and VisualizeTargetPose functions
  • Use this script to create a camera calibration. Built-in camera calibration is coming soon.

• Module API Changes:

  • force_enabled has been removed. Functions now load from imported modules by default.

Post-Kickoff Update Hotfix

Packages

• Fix issue where python3-upgraded-engineer and rusty-engine would automatically be removed
• Add python3-gst-1.0

OpenSight Post-Kickoff Update - Now with H.264, Contour Filtering, and more!

OpenSight

• Contour Filtering: You can filter contours by…

  • Area
  • Rectangular area (both bounding and minimum area)
  • Speckle removal (filters out contours that are much smaller than the largest contour)
  • Aspect ratio
  • Orientation
  • Angle
  • Top-most, Bottom-most, Left-most, Right-most, Most central, largest, and smallest contours (e.g. only pass the 2 biggest contours)

• Color sampling and detection:

  • ColorSampler: New function that provides provides the color of a given pixel in an image
  • ColorDetector: New function that returns which of four colors a given color is closest to by hue. Useful for the CONTROL PANEL when coupled with the ColorSampler.

• You can now choose between DHCP and static IP in the settings tab.

• H.264 Video Streaming via rusty-engine

  • Brand-new rusty-engine RTSP server with support for Video4Linux2, Raspberry Pi Camera Module, and shared memory socket input.
  • upgraded-engineer Python package to easily write frames from an OpenCV Python application to rusty-engine.

v0.2.0-rc.3

OpenSight

• Fix for gstreamer-shuffleboard compatibility.

v0.1.4

Packages

• Added log viewer and console access
  • Go to opensight.local:5800 for access to the console, or go to opensight.local:5800/logs to see the logs for the OpenSight service.

v0.1.3

Note: If upgrading from a previous version, you MUST install v0.1.2 before this release. If you have a version before v0.1.2, you must install v0.1.2 and then v0.1.3.

OpenSight

Features

• GPIO LED support
  • LEDs and PWM LEDs can now be turned on/off through the Raspberry Pi's GPIO interface
• Logic module
  • Freeze node: enable "freeze" to stop the nodes connected to the output from running
  • A framework has been built for conditional modules in the near future
• Circle Detection
  • Detect and find circles using the new AbsoluteDifference functions (HSV and RGB), Clamp Min/Max, FindCircles, and Draw Circles functions (docs WIP)
• Line Detection
  • Detect lines using the Canny, FindLines, and DrawLines functions (docs WIP)
• GetNT
  • Get NetworkTables values using the GetNT function. Useful for setting LEDs and other parameters.

Tweaks and Fixes

• Nodetree import time has decreased substantially. For example, your changes to HSV filters will take effect immediately rather than after 5-10 seconds.
• HSV is now scaled to 360, making it easier to figure out what each color is
• Dropdowns automatically select first camera, fixing issues where the camera could not be selected.

Packages

• Added python3-gpiozero

Raspberry Pi Image

• Fix CA certificates not being updated

v0.1.2

Changelog:

OpenSight

• Dramatically decrease shutdown time
• Fix webserver not closing properly

• Server mode in NetworkTables now uses opensight.local instead of localhost

Packages

• Upgrader script is now stored in upgrade tarfile rather than in OpenSight source

Raspberry Pi Image

• Automatic EEPROM updating has been disabled in order to ensure it is not triggered without steady power.

v0.1.1

Changelog:

• Automatically remove unneeded nodes from the nodetree run order
