基于PixelGrid的无人机影像DEM精度评价

DEM accuracy evaluation of UAV image based on Pixel Grid

无人机低空遥感在小范围大比例尺地形绘制领域效果优良,文章基于PixelGrid软件,提出了一种无人机航测影像DEM数据快速、高精度生产流程,并利用具体无人机测绘数据进行演示,最后通过与实际测量数据进行对比验证,结果表明文章采用的方法满足精度要求。

Low-altitude remote sensing of using UAV is effective in small-range and large-scale terrain mapping. Based on the PixelGrid software, this paper presents a fast, high-precision production process of DEM data of UAV image. Then specific UAV surveying and mapping data is used for demonstration. Finally, the comparison with the actual measurement data proves that the method adopted in this paper meets the precision requirements.
