Analyzing and Improving the Camera Plane Calibration Method

Analyzing and Improving the Camera Plane Calibration Method

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. T...
