In order to obtain an accurate correlation between the 2D image information obtained by filming and the information of its corresponding 3D object

and to reduce the effect that the distortion of CCD camera lens has on the image

a correct mathematical model is set up. Based on the MATLAB camera calibration toolbox

the projection matrix consisting of the camera's internal and external parameters is obtained. Thus

the correction process of the distorted image is completed. In the process of calibration and solving

detailed description and analysis of each step in operation is given

the data results are constantly optimized

and by simultaneously calling the space stereo image model

the experimental data is more directly presented. The verification of the correction of the image captured by the same camera

using experimental data

is made. The experimental results indicate that the distorted image has been effectively restored. Overall

the proposed method is simple

time-efficient

direct

accurate and of significant utility.
