摘要 针对目前市面上制作的DSM信息表达不丰富、效率不高的问题,该文提出了采用PixelGrid生产高保真高效率DSM的工艺流程,主要从不同重叠度、不同量化级别影像、不同格网尺寸等3方面进行DSM成果的影响因素分析。该文详细阐述了利用PixelGrid软件进行生产试验,得出重叠度大小的方法、不同量化级别影像和匹配格网大小的方法,对生产高保真高效率的DSM成果具有一定借鉴意义。 Currently,the technology of DSM production has the problem of non-abundant information and low efficiency.This paper analyzed the influence on DSM and indicated that PixelGrid software can produce high-precision and high-efficiency DSM.It also concluded that overla Psize,different level of image quantization and grid size can make influence on the result of DSM production.
