Digital image processing is to modify graphics, improving image quality and extract valuable information from the images.The detection technology based on machine vision is more applicable for the dangerous environment and situations that difficult to find, it is can also avoid the error generated by human vision.This paper introduces the precise measurement technology based on machine vision, and distortion correction theory was studied by the nonlinear optimization which is based on the traditional camera calibration method, then the samples were measured by edge detection with Sobel operator.The result shows that this method is promotive to the accurate measurement.
