Real time re-calibration of stereo cameras

摘要

Described are image and video processing systems and methods for auto re-calibration of stereo camera devices. The auto re-calibration processes described herein transform image data into re-calibration data used to correct calibration errors in real time. The auto re-calibration processes leverage position data shifting, image data filtering, and disparity analysis to generate one or more calibration profiles that track the position of the camera modules included in stereo camera devices. Calibration profiles are then used to generate pixel shift parameters describing how to modify the position of image pixels and or camera modules to improve rectification and projection of 3D images and video frames. Additionally multi-camera systems implementing the auto re-calibration processes are disclosed.
