面阵数码航摄像控测量布设的思考

对在像控测量布设中遇到的2个问题进行了阐述,得出航线网精度估算式仍然适用,但数码航摄仪的像控点数量应多于光学航摄仪的结论。另外,在满足一定的条件下可进行跨航线布点,像控点的选点目标需要顾及成图精度要求,不能照搬现有规范要求。

Research on the Distribution and Target for Frame Digital Aerial Photo Control Points

This paper emphasized on the presentation of the setting and selecting photo-control points in the photo-control point measurement. We draw some conclusions that the air route network accuracy estimation formula is applicable, and the number of photo control point of the digital aerial camera should be more than the optical aerial camera’s. In addition, in some certain conditions, it is feasible to set control points crossing the air routes, and the mapping precision should be considered when selecting control points, but not according to the existing specifications.
