摘要
介绍了机载POS系统对地定位的主要方法和基于POS系统制作1∶1万比例尺数字正射影像图的过程。结果表明,利用POS系统对地定位只需少量地面控制点即可解算出高精度的外方位元素,进行相应比例尺的航测成图与正射影像图制作。该方法生产效率高,成图周期短,展示了POS系统在正射影像图制作方面具有广阔的应用前景。
This paper deals briefly with the compilation process of the 1:10 000 digital orthophoto map (DOM) in some areas based on POS. The result shows that the orientation method named Integrated Sensor Orientation (ISO) can use only a few control points to calculate the parameters of exterior orientation with high precision and meet the demand of DOM production with great efficiency, thus shortening the map - construction cycle. It is shown that this method has a wide application prospect in the production of DOM.
