The merits and demerits of frame differential method in motional detecting were analyzed and optimized. 详细讨论了运动检测中帧差法的优缺点,并设计了快速实现算法,同时提出了对原有方法的改进。
The general eddy current flaw reconstruction strategy was the least-square error method, which required the forward solver having high speed. 在涡流检测中,常利用最小方差法来进行缺陷重构,这种方法要求正问题的求解效率高。
