摘    要:可以展望利用卫星三线阵CCD影像自动采集的DEM、按共线方程将三线阵CCD影像变换为正直摄影像对(Normal case photography)提供用户立体测绘。文中着重讨论了正直摄影像中不在DEM表面上的目标点的位置误差,以及改进的立体测绘数学模型。利用卫星获取的前、后视CCD影像,并在其上添加由计算机生成的高层目标(约300m)的图像,验证了生成的正直影像对立体测绘的可行性,试验的高层目标点的坐标量测中误差为实验影像的0.5像元之内。

关 键 词:卫星摄影测量  正直摄影影像  立体测绘

Abstract:The paper discusses the affine deformation about the normal case image transformed from Push-broom CCD image due to the object outside the DEM and improved mathematics model for the stereo mapping. With three-line-array CCD image and computer simulating image of 300m high building as experiment data, the result shows that the mean square root coordinate error are less than 0.5 pixel. It is expected that normal photography image will be a production from satellite company after DEM and ortho-image.
Keywords:satellite photogrammetry  normal case photography imagery  stereo-mapping
