Description
Summary:An improved method for camera plane calibration is proposed by analyzing and testing the two-step calibration method based on plane. In the improved method, central area of images is used firstly to solve initial values of the camera intrinsic parameters, improving precision of the initial values. Then, to facilitate dimension measurement using machine vision, the lens distortion model is modified and the projection direction is changed. Experiment results show that the improved calibration method could increase camera calibration precision, and easy to operate. It can be used in the machine vision research and the industry 3D measurement.
