Then I have a circular area on the Color frame.\r\nI want to get the depth for those pixels in the big Color frame. So I am integrating Registration::apply in the libfreenect2 modified for Jetson, but I cannot understand a thing:\r\nIn a post I read that \"undistorted\" is the rectified depth map. Is it equivalent to the argument Frame *depth ? If no, could you tell me how to get all necessary parameters, in order to have bigdepth filled correctly?
