Research Spatial Triangle Calibration Algorithm in Camera Measurement
Spatial triangular calibration algorithm is proposed to improve the complex problem of traditional onedimensional camera calibration,and decrease calibration cost.The algorithm of camera calibration was studied by using the method of camera triangle rotation,geometric model of triangular calibration algorithm was set up,and the calibration parameters of camera were calculated by spatial triangle geometric relation.Camera shoots two pictures when spatial triangle rotate,the information of triangle side length was regard as constraint conditions and set up linear equations,at last,the calibration parameters can figure out,the software of Matlab was applied to simulate calibration algorithm,the result indicates that the calibration algorithm of triangle rotation is very simple,convenient,and has high precision.It can apply in all kind of camera calibration.
