An automatic fringe detection algorithm applied to moire deflectometry is presented. This algorithm is based on a set of points linked together and with a behavior similar to a rubber band, in which these points are attracted to fit the moire fringes. The collective behavior of these points gives rise to a final state which is their regularly spaced alignment along the fringe pattern. The algorithm is dynamic in the sense that it tracks the fringe even when it suffers continuous deformations. Once the rubber band is adapted, the rubber band's points coordinates are obtained and their distance to the starting straight line is found, as required by moire deflectometry.
提出了一种应用于莫尔偏折术的自动条纹检测算法。该算法基于一组相互连接且行为类似于橡皮筋的点，这些点会被吸引以拟合莫尔条纹。这些点的集体行为会产生一种最终状态，即它们沿着条纹图案规则间隔排列。该算法具有动态性，即使条纹不断变形也能对其进行跟踪。一旦橡皮筋适配完成，根据莫尔偏折术的要求，获取橡皮筋点的坐标并求出它们到起始直线的距离。
