精确自动识别莫尔条纹方向角的算法
Accurate and automatic recognition of Moiré fringe angle
摘要
Abstract
As traditional methods for calculating Moiré fringes can′t satisfy the demands of precision and calculating speed,a fast method that can figure out the angle of the Moiré fringes accurately is put forward in this paper.According to the principle of the Root Mean Squared Error（RMSE） that the closer a series of data is,the smaller the value of the RMSE will be,the angle of the Moiré fringe α is come out primarily.Then Mean-Shift algorithm is used to calculate the angle of Moiré fringe accurately in the neighborhood of the angle α.Experimental result shows that when the contrast level is up to 5.4%,the precision of angle calculation achieves 29′ according to the evaluation index of angle detection error.The computing speed of the algorithm has been increased largely as compared with those of the traditional methods,and it can achieve 15 ms,and satisfies the demand of real time.关键词
