Extraction de façades utilisant la stéréoscopie par corrélation sur des images aériennes transformées
Résumé
We present in this paper a new approach for building extraction from aerial images. This approach is composed of two parallel processes: the first one deals with horizontal surfaces (ground and roofs) and the second one with vertical surfaces (facades). Both processes use a standard stereo by correlation algorithm: the first one on a rectified pair of images, the second on a rectified and transformed pair. The transformation we use corrects the vertical surfaces to give them the same aspect on both images. The first results show a good localisation of facades.
