blackboard2api's Issues
StackOverFlow entry for differences
Add Pylint to Actions
Clean up Code and move to OO
Ideas for Blackboard Detection
- Harris Detector
- Hough Transformation
- Grünwert
- Canny
- Hough with HSV Green Value
Setup Github Actions: Python Application or Python package..
Beide sehen gut aus, wählt einfach eins aus ;)
Evaluation of different methods
- collect criteria
- define the layers of the solutions for a morphological box template
- collect solutions in morphological boxes
- weight criteria
- score solutions
make main class from main.py
Presentation
- create PPT for OOP
- create PPT for mechatronisches Projekt
- who says what
Documentation
- define criteria
- explain the challenges (perspective, distortion, reflection, ...)
- description camera calibration
- list of versions used of opencv, python, numpy etc.
Edit: Some tasks were put to a new issue
calibrate from live feed
Get Blackboard via Green Channel
- create mask from green value
- get contours from mask
- find biggest contour
- Use Hough Detector after Green Mask
- return None if no Green Area is detected or too small
- write tests
Reflection
- try with a polarizing filter
Create method to apply distortion matrix to videocapture
Compare coordinates to previous frames
Comparing coordinates of blackboard to coordinates of previous frames to get rid of jitter
Test Videos
- collect parameters
- plan series of experiments
- record the videos
- write explanatory texts for the series of experiments
- upload the videos in the project
Camera doesn't work
The Camera takes multiple minutes to start up. Then it only delivers 480p images.
Even when requesting higher resolution, it just returns an upscaled image.
Tested on multiple systems
Write Getting Started
-
find out whether English or German is required for OOP
-
short description of the purpose of the project
-
requirements (versions of Python and libraries, hardware requirements)
-
how to start and stop the application
-> ca. 1 page
Pytest
Die CI Pipeline / Actions aus #3 rufen pytest sowieso automatisch auf, aber es sollten dann auch Tests im Repository sein.
Wenn ihr möchtet, kann ich euch dazu auch ein Notebook schicken..
Camera Calibration
Calibrate Camera using Chessboard Image
- calibration -> static method
- write test function for calibration (including test of the mask in the setter functions)
Graphics
- UML classes
- flow chart loop
Add timestamp (and isValid) to object
