基于POS系统的1:1万比例尺正射影像图制作

THE CONSTRUCTION OF 1:10 000 ORTHOPHOTO MAPS BASED ON POS

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.
