I downloaded an OpenCV.js from here. But I just realised that there is no RQDecomp3x3 method. I need to get angles from the rotation matrix. Any suggestion?

CodePudding user response：

According to Chirstoph Rachwitz's suggestion here

I just added RQDecomp3x3 in opencv_js.config.py, and compiled the library again

calib3d = {
'': [
    ...
    'projectPoints',
    'undistort',
    'RQDecomp3x3',
    ...
],

}
