基于影像快速处理系统的DSM生产方法

Producing method of digital surface model(DSM)based on pixel factory and pixel grid

充分发挥新型影像快速处理系统pixel factory与pixel grid的优势,利用资源三号卫星立体影像,提供一套可行、高效的DSM生产方法,并用实际生产数据进行试验。试验结果表明:利用影像快速处理系统pixel factory与pixel grid,可高效、高自动化地生产高精度数字表面模型DSM,可以为大规模的进行DSM与DEM快速生产提供一定的经验指导与技术支持。

With the development of surveying and mapping geographic information industry and service transformation ,the demand of digital surface model（DSM ） is becoming more and more in all walks .How to produce high precision DSM quickly is imminent .Based on the system of pixel factory and pixel grid and using ZY‐3 stereo satellite images ,an feasible and efficient DSM production method is proposed .Moreover ,one set of actual data obtained by Lecia RCD‐30 is used to test .All the results show that based on the system of Pixel Factory and Pixel Grid ,the high precision DSM can be produced efficiently and highly automated .The results also provide some experience guidances and technical supports to the large‐scale production of DSM and DEM .
