Method of Automobile-Sensitive Component of Safety Belt's Dimensional Inspection Based on Machine Vision

Abstract:

The purpose of this paper is to measure the open size of automobile-sensitive component of safety belt by the method of machine vision. At first ,use the CCD camera to get images of the component. Then the software (NI Labview) can help to process those images easily. The needed edge points of the component in the picture can be found after image has been processed by filtering, gray-scale morphological processing, binaryzation and edge detection which has been implemented by Canny algorithm. Through those points we can get the result of the beeline equation by least square method, and finally detected the angle between the two straight lines which stand for different straight edges of the component .And the detected angle values is the open size we need .
