Title
Multipass hierarchical stereo matching for generation of digital terrain models form aerial images
Abstract
This paper presents a new multi-pass hierarchi- cal stereo-matching approach for generation of digital terrain models (DTMs) from two overlapping aerial images. Our method consists of multiple passes which compute stereo matches with a coarse-to-fine and sparse-to-dense paradigm. An image pyramid is generated and used in the hierarchical stereo matching. Within each pass, the DTM is refined by using the image pyramid from the coarse to the fine level. At the coarsest level of the first pass, a global stereo-matching technique, the intra-/inter-scanline matching method, is used to generate a good initial DTM for the subsequent stereo matching. Thereafter, hierarchical block matching is applied to image locations where features are detected to refine the DTM incrementally. In the first pass, only the feature points near salient edge segments are considered in block matching. In the second pass, all the feature points are considered, and the DTM obtained from the first pass is used as the initial condition for local searching. For the passes after the sec- ond pass, 3D interactive manual editing can be incorporated into the automatic DTM refinement process whenever neces- sary. Experimental results have shown that our method can successfully provide accurate DTM from aerial images. The success of our approach and system has also been demon- strated with a flight simulation software.
