The recognition of the internal corners of a planar checkerboard calibration pattern image is very important to camera calibration. An effective approach is proposed to automatically recognize the internal corners of the planar checkerboard calibration pattern image based on the characteristics of local intensity and the grid line architecture of the planar checkerboard pattern image. The proposed...
In this paper, chess-type plane is used as calibration patterns, and the camera is calibrated by utilizing linear camera model with sub-pixel precision, we propose an improved algorithm used to locate the position with the visual information. The new method is based on improved SUSAN detecting and is combined with quick image matching which is used to get the coordinates of the end executor of the...
