I am working on aligning my depth stream to color stream using my Femto bolt camera. For doing this, I noticed that there is an already existing function called AlignFilter() that handles this. I used this function to generate my color world aligned point cloud and it works pretty well. However, I also noticed that this function uses factory intrinsic and extrinsic to do this process. I want to avoid using those values and use my self obtained camera parameters instead. Is it possible to access how this function works and modify it to use my parameters instead to improve the accuracy? I also saw that the distortion coefficients are also set to zero which I am not sure about.
