(一)概述:利用像片平面圆测图是航测成圆很好的方法,因为它的精度高而显示的内容很丰富,所以在平坦地区时都是尽可能地采用这种办法。当在地形超伏比较大的情况下,一般都采用分工法和全能法成圆。在全能法成固过程中不再考虑像片平面圆的问题,而在分工法成圆过程中;在中国也很少采用像片平面圆的办法。这主要是在地形起伏较大的地区,利用已往分
(A) Overview: The use of photogrammetry circle mapping is a good method of aerial mapping into a circle, because of its high precision and shows a wealth of content, so in flat areas are as far as possible to adopt this approach. When the terrain overvoltage relatively large circumstances, the general division of labor and all-round method into a circle. In the process of Almighty Act solidification no longer consider the problem of the image plane circle, and in the process of division into a circle process; in China is also rarely used picture plane round approach. This is mainly in the area where the topography fluctuates, making use of the past points
