 Not only the requirements of the application must be met, but also the visual disparity, illumination, performance of camera and the feature of scenario should be considered.Camera calibration in Binocular Stereo Vision refers to the determination of the mapping relationship between the image points P1(u1,v1) and P2(u2,v2), and space coordinate P(xp, yp, zp) in the 3D scenario.Camera calibration is a basic and essential part in 3D reconstruction via Binocular Stereo Vision.
