Hello everyone, I am using a stereo camera to process the images in order to work with point clouds. I am using a method proper to the PCL library to create those point clouds (shame on me) but anyway, here is my problem: The camera sensor resolution is 1/3.2" 752x480, it has a baseline of 12cm and a focal length of 2.17 mm.
I managed to convert the focal length to pixels and pass it as well as the other parameters to the function that I am using to create the point clouds. It could be faster if I was reducing the initial image resolution: I would like to pass from 752x480 to 263x168 (35% of the initial resolution) in order to process the clouds faster. I am currently stucked on this problem: How to transform the previous parameters to adapt them to this new resolution. I checked the OpenCV camera calibration documentation but I didnt find what i was looking for (maybe I didnt looked into it properly).
could you help me on this?
thank you in advance
