jevois::CameraCalibration Class Reference

#include <jevois/Core/CameraCalibration.H>

Helper class for camera calibration, which allows some modules to compute 3D locations of objects.

This code heavily derived from calibrate_camera.cpp in the OpenCV source tree. Keep it updated as OpenCV is updated.

Definition at line 28 of file CameraCalibration.H.
