If the eyepiece of a total station is replaced with a CCD sensor, the most important task is to calibrate the instrument. Calibration establishes a connection between the readings on the horizontal and vertical circles of the total station and the readings in the coordinate system of the CCD sensor. Our calibration method uses a collimator in a few meters distance, which serves as a target at infinity during the calibration. We tested the calibration using a QDaedalus astrogeodetic measuring system. The optimal number of calibration measurements, the optimal raster size, and the temperature dependence of the measurements were investigated.

大地测量系统上安装的CCD传感器的校准

如果将全站仪的目镜更换为CCD传感器，则最重要的任务是校准仪器。校准会建立全站仪水平和垂直圆上的读数与CCD传感器坐标系中的读数之间的联系。我们的校准方法使用几米距离内的准直仪，该准直仪在校准过程中用作无穷远目标。我们使用QDaedalus天地测量系统对校准进行了测试。研究了校准测量的最佳数量，最佳光栅尺寸以及测量的温度依赖性。
