Study on the Alignment and the Calibration of a Laser Structured Light Sensor

In this paper, the principle and the application of the two dimensional laser structured light sensor are introduced. A new method for the alignment and the calibration of the laser structured light sensor are proposed. In this method, the optical collimating and the computer graphic positioning technology are used. Therefore, the processing of the alignment and the calibration of the laser structured light sensor has been simplified and the required accuracy can be reached.
