从航摄照片恢复地形、地貌的技术,在航空摄影测量和地质科学中有着广泛的用途.例如,通过航摄照片可以用数学方法测制正射影象地图,进行重力地形改正等.这两项技术是航空摄影测量和地质探矿中的重大技术革新,可以大大缩短成图和探矿周期,提高精度,节省大量人力和物力.而实现这两项技术的核心问题是根据航摄照片恢复地形的方
This paper discusses two new algorithms for obtaining the height of an arbitrary point onthe ground directly through photographs. They Can be efficiently used to compute the terraincorrection of gravity and operate an orthophoto with contours. The programming for the newprocedures is much simpler and clearer than the algorithms available. The memory spacerequired has been reduced to the minimum, and the amount of operations is more economical,especially in the case of terrain correction of gravity. This paper gives also some numerical examples for two mathematical models of terrainby means of fabricating photographs.
