Explain camera parameters

3

Hi, Can you explain which parameters are (distortion parameters) and which are (intrinsic parameters), such that in Pinhole parameters, there are up to 8 distortion parameters, and 2 focal lengths,...

How to use generic model in Colmap?

2

Hi, @puzzlepaint In the paper Colmap reconstruction is used as an evaluation. Do you undistort the images first, then give the undistorted images to Colmap? Or you integrate the generic-model...

How to manipulate the grid points for some warping application

1

Hi @puzzlepaint , I want to manipulate the grid points of generic model of camera for some other warping application. I have read the function `bool TestCentralGenericCameraReprojection()` https://github.com/puzzlepaint/camera_calibration/blob/2682d587e1272b8e2ab845074bdf050cf9248ef0/applications/camera_calibration/generic_models/src/main.cc#L38 However, I...

Hi, because depth computation doesn't work without the GPU, and I'd like to try my own stereo algorithm on images, I was wondering if it would be possible to get...
