COMPUTING DEVICE AND METHOD OF DETERMINING BORDER POINTS FOR MEASURING IMAGES OF OBJECTS

摘要

In a method of determining border points for measuring an image of an object using a computing device, grayscale values of pixel points in an image being measured are acquired, and definition values of the pixel points are computed according to the grayscale values. A line which intersects with the image being measured is constructed, and the definition values of the pixel point values in the lines are obtained. A location range of a border point of the image being measured is determined according to the definition values of the pixel point values in the line, and the border point is selected from the location range. A border line of the image being measured is fitted using the border points.
