| Abstract: | It is very important to correct the camera lens distortion for getting the precise image and locating the correct position of the object in robot vision detection and auto selection.The pin-hole camera model with radial lens distortion and the calibration method based on segment slope is used.Radial lens distortion coefficient can be obtained by linear algorithm in the calibration.The experiment shows that the calibration method is effective and simple and its calibration result can meet the need of the research work. |
