A CRT Convergence Analyzing Tool based on OpenCV
This a simple proof-of-concept program that demonstrates the same functionality as advanced CRT convergence tools from back in the day. To do this, it follows a few steps:
- Identify dots from a dot test pattern
- Crop and scale/interpolate each individual dot
- Look for areas with excessive red and blue contours
- Calculate scaled vector to represent severity of mis-calibration
- Take all data and analyze for global patterns (Still in Progress)
The tool is simple to use and only requires a path and scale factor (0-100). It requires that the OpenCV library is installed.
