本文对变符号准则匹配法进行了理论分析.证明了在不考虑遮挡和几何失真的条件下,匹配点处的符号变化次数为最大,并且对于该算法的抗遮挡性能进行了讨论.在DPS-8/52计算机系统上用图象进行了大量的模拟实验.理论分析和实验结果证明,变符号准则匹配方法不仅在信噪比小于1的情况下能够正确匹配,同时在特定条件下具有抗遮挡的能力.
In this paper, the theory of variable symbol matching is analyzed theoretically.It is proved that the number of symbol changes at the matching point is the maximum without considering the occlusion and geometric distortion, and the anti-blocking performance of the algorithm is discussed.At the DPS- A large number of simulation experiments were carried out on the computer system using computer graphics. The theoretical analysis and experimental results show that the variable symbol matching method can not only match correctly when the signal to noise ratio is less than 1, Ability.
