摘　　要：将立体匹配转化为求物理模型的平衡状态问题,提出了基于物理模型的立体匹配方法,为了克服局部最优问题及解对初始模型的敏感问题,采用位于真实视差表面两侧的两个物理表面模型,在迭代过程中对能量较大的表面附加驱动力,使其靠近另一表面,直到两个表面收敛到同一个解,为了进一步提高匹配的速度,采用了多分辨率算法、实验结果表明了该方法的有效性。We propose a stereo matching method which based on physical models , and introduce the controllable continuity constraints to confine the solution to the smooth space while preserving disparity surface discontinuity. To avoid local minima and decrease the sensitivity to the initial model in stereo matching, we use two physical models, each of which is located on the opposite side of the disparity surface. An additional driving force is added to the physical model with higher energy to drive it towards the other model, and the process is repeated until both models have the same solution . In order to increase the speed of matching , the multi - scale surface matching algorithm is proposed. Some experiment results are shown to demonstrate the effectiveness of our method.
