Binocular Camera Calibration Based on Perspective Transformation Algorithm
Camera imaging model is established to realize binocular vision calibration.Interrelation is established be-tween camera coordinate system and image coordinate system by using Pinhole imaging model.The inner and outer ma-trix parameters of binocular camera are solved by perspective transformation algorithm,and then the position relationship between the two cameras is determined to complete the calibration of binocular stereo vision system.Finally,the accuracy of the calibration method is verified by experiments.the calculated results with the measured results in three-dimensional coordinates shows that the error in the X direction is within 0.700mm,the Y direction is within 0.500mm and the Z di-rection is less than 0.600mm.The calibration results are accurate.It provides effective support for machine vision positio-ning such as target recognition and detection technology.
