摘要
为满足大比例尺测图对无人机航空摄影测量的要求,采用理论分析和实例研究相结合的方法生成正射影像图(digital orthoimage map,DOM),探讨了DOM生成过程中的影像畸变纠正、控制点布控、影像镶嵌以及海量数据处理等关键技术.以天津师范大学主校区为试验样区,对技术路线进行验证,结果表明:提出的方法具有可行性,可以满足1∶2 000比例尺测图精度的需要.
In order to meet the requirements of large scale mapping to the UAV photogrammetry, the digital orthoimage map （DOM） was generated by combining theoretical analysis and case study. The key technologies during the process of the DOM generation such as image distortion correction, control points supervision, the image mosaic and huge amounts of data processing were discussed. Take the main campus of Tianjin Normal University as a sample to test the workflow, the results show that the method adopted in this paper is feasible, and can meet the need of 1 ： 2 000 scale mapping precision.
