Abstract :
The problem of 3-D reconstruction from three digital angiographs is discussed. The solution described is based on trinocular vision and performs the matching of segments. All the pairing possibilities are first defined using geometrical constraints and a global control is applied through a simulated annealing algorithm. The method has been tested on simulated images and on real images of a wire-heart phantom. The results were judged very promising
