Camera calibration problem using Matlab Toolbox #181

Closed scottybit closed 8 years ago

scottybit commented 8 years ago

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...?

You don't have to use Matlab for that. There are some alternatives such as an opencv sample (usable as a standalone) or simply GML.
