Research on Camera Calibration System Based on Binocular Stereo Vision

Chunyan Yang
Get the information of the three-dimensional object from the two-dimensional image, camera calibration is an essential and critical step. The position of a three-dimensional object, geometric information such as shape and state can be obtained from 2D image only by camera calibration and thus the information...
