Abstract:

In order to improve the efficiency of X films detection in industry, a method using the automatic microscopy instead of the naked eyes to detect the X films is offered, and by researching the character of the microscopy sampling and the X film image, a fast approach of image stitching using gray relativity of pixels is proposed: taking out midpixel of the last row of frontal sampling image to construct the matching matrix, making the threshold， finding the matching pixel in the next image by getting the correlation, and validating the veracity by circle checkout. According to the experiment, this approach is of perfect accuracy and efficiency.

Key words: automatic microscopy, relativity, threshold, matching, validating
