Traditional methods for geometrical camera calibration are based on calibration grids or single pixel illumination by collimated light. A new method for geometrical sensor calibration by means of diffractive optical elements (DOE) in connection with a laser beam equipment is presented. This method can be especially used for 2D-sensor array systems but in principle also for line scanners.
传统的几何相机校准方法基于校准网格或准直光的单像素照明。本文提出了一种利用衍射光学元件（DOE）结合激光束设备进行几何传感器校准的新方法。该方法特别适用于二维传感器阵列系统，但原则上也适用于线扫描仪。
