Improved method of the plane-sweep strategy in the task of building reconstruction from aerophotographs

The tasks of detection and three-dimensional reconstruction of buildings are to be often solved as part of the terrain digitizing problem. Most of the algorithms used to solve this problem are too general and, as a result, are ineffective either in accuracy or in terms of operation time. In this paper we propose to use a modification of the plane-sweep strategy method. As a result of the proposed improvement, the reconstruction process is accelerated several times, while providing comparable quality.
