摘要
研究目的:介绍不同遥感数据DOM制作流程及其关键技术,探讨实际作业中应注意的问题及解决方法,提高正射影像图精度及生产效率。研究方法:实验法与比较分析法。研究结果:(1)从正射纠正、融合、镶嵌、色彩调整等方面对比分析,提出了较好的影像处理方法;(2)对于纠正误差,可采用局部纠正和影像替换方法解决。研究结论:整体纠正、Pansharp变换法、Photoshop工具色彩调整等可以有效提高成果质量,消除误差。
The purposes of this paper are to introduce the to different types of remote sensing data, and discuss the precision of orthophoto map and production efficiency. making process of DOM including the key techniques regard problems and solutions in practice in order to improve the Methods of experimentation and comparative analysis were employed. The results indicate that：（ 1 ）better image processing methods were proposed through comparative analysis on aspects of ortho-rectification, image fusion, mosaic and color adjustment, etc.; （2）the errors can be corrected by partial rectification and image replacement. It is concluded that by the means of integrated rectification, Pansharp fusion and Photoshop color tools can improve the quality of products effectively and eliminate the errors.
