Repository files navigation

THIS PROJECT IS NO LONGER SUPPORTED, AND COMPLETELY NON FUNCTIONAL FOR ANYTHING PAST THE ROVER RUCKUS SEASON.

PLEASE CHECK OUT EASYOPENCV, WHICH LETS YOU USE OPENCV IN FTC. IT HAS GREAT EXPLANATORY EXAMPLES THAT CAN BE ADAPTED TO WHATEVER THE CURRENT SEASON IS.

DogeCV

An easy to use computer vision library used for FTC Games to detect game objects. Based on EasyOpenCV and OpenCV.

Project Status:

No Longer Developed

DISCLAIMER

THIS REPO IS STILL UNDER CONTINUOUS DEVELOPMENT. WE WILL BE ADDING FURTHER DOCUMENTATION, BUG FIXES, AND NEW FEATURES

To run this library, you need an SDK version of at least 5.1

Unfortunately, this library will not work on the ZTE phones, as OpenCV does not work on KitKat.

Unfortunately, the video tutorials, are outdated and will be updated soon. Please read the installation directions and be check out the examples inside the code. Please contact any of the developed if you need help!

Videos (OUTDATED!!!)

Wizards.exe have been amazing with their DogeCV coverage, so please check them out and give your support, the videos are easy to understand and well made, great for people who want to learn DogeCV for past versions. Please do keep in mind that these tutorials are for older versions of DogeCV and will not work for the newest version.

Detectors Status

  • Stone Detector - Implemented. Needs improvement.
  • Skystone Detector - Implemented. Not Reliable, Under rewrite.

Install (Credit to EasyOpenCV)

  1. Pull up Android Studio, with the FTC application SDK open
  2. Go to the root build.gradle
  3. To the repositories section, add the lines
allprojects {
  repositories {
    maven { url 'https://jitpack.io' } // this line!
  }
}
  1. Add the line implementation 'com.github.dogecv:dogecv:2020.4-alpha' to TeamCode's build.release.gradle, inside the dependencies block
  2. Press the Sync Now button that should appear in the top right
  3. Because EasyOpenCv depends on OpenCV-Repackaged, you will also need to copy libOpenCvNative.so from the /doc folder of that repo into the FIRST folder on the internal storage of the Robot Controller.

Known Issues

(These issues are referring to the 2019-2020 FTC Year Detectors, and not the Relic Recovery or Rover Ruckus ones as those are no longer supported)

  • Skystone detectors aren't accurate
  • Stone detectors aren't accurate

Planned Features / TODO

  • Expand Wiki
  • Add in distance scoring between samples to increase accuracy
  • General Code Clean up
  • Basic angle/positioning of elements
  • Port Old detectors to new systems
  • Better Safety checks
  • New Frame Input System
  • ML detectors

FAQ

  • Can I still use classic OpenCV? Yes! We want teams to use DogeCV to learn about vision and start to create their own vision systems. That's why OpenCV is open in all layers of DogeCV, and we keep the classic OpenCvPipepline introduced in the EasyOpenCV library.
  • Can I use a webcam? Once more, yes! See the DogeQuickStart and the wiki for an explanation of how to this.

Changelogs

2020.1-alpha:

  • Changed to EasyOpenCV from EnderCV (thanks OpenFTC team!)
  • Added StoneDetector
  • Added SkystoneDetector
  • Removed legacy detectors (may be added back later)
  • Added DigitalCamera class for localization

2019.1:

  • Complete re-work of the Dogeforia system. It is now integrated within the OpenCVPipeline class, and is much simpler.
  • Implemented image cropping, see CroppingExample
  • Fixed miss-rotation in Vuforia display. The image should now be correctly oriented on the RC display
  • Added VuMarkExample OpMode to demonstrate the basics of the new system
  • Added WebcamGoldExample OpMode to demonstrate how to use a webcam with a detector under the new system
  • Added `GoldAndVuMarks
  • Added CroppingExample OpMode, intended to ease image cropping and to showcase functionality
  • Added GoldExample OpMode
  • Added method getYPosition() to GoldAlignDetector
  • Added VuMarkDetector to provide a ready-made detector for the VuMarks within DogeCV. I will have it highlight VuMarks at a later date
  • Added enum VuMark to DogeCV to make dealing with VuMarks easier in code
  • Added enum 'CameraModetoDogeCVto make setting the camera betweenFRONT, BACK, and WEBCAM` easier
  • Added wiki entries for VuMarks and Webcams
  • Reworked code comments

  • Moved SamplingOrderDetector to use HSVRangeFilter for silver
  • Tuned Sampling (Still not competition ready)
  • Cleaned up Dogeforia handling per suggestions of "@BillTheCat123 | Mentor | 3763" on FTC Discord
