Recently I was trying the LSD_SLAM, using "Camera Calibration Toolbox for Matlab" to compute the intrinsic coefficients. However, the coefficients seemed to have large error, since I calibrated the camera multiple times. I was wondering, is the coefficients from matlab toolbox applicable? Must I use PTAM cameracalibrator to obtain the fx,fy,cx,cy...?
