| Abstract: | To acquire 3 D information quickly, structured light ranging is widely used in computer vision and topography. Based on the applications and given conditions, DLT model is simplified. 3 D calibration can be implemented successfully and quickly through 2 D measuring and computing. To get the higher accuracy, the calibrating error is analyzed and the algorithm is improved. The experiments demonstrate the calibration accuracy of the algorithm can be in pixel. |
