基于机器视觉的安全带气体发生器颜色检测方法

对基于机器视觉的汽车安全带气体发生器的颜色检测方法进行研究,研究的目的是检测出该元件的颜色信息。使用的方法是:采用彩色CCD相机获得被检测元件的彩色图像;对获取到的彩色图像使用美国NI公司的Lab VIEW软件及其图像处理模块来实现彩色图像的色偏调整、彩色图像的滤波处理等操作后获得可用于检测的理想彩色图像;将获取到的各种不同的气体发生器的颜色图片保存为标准模板,之后检测到的元件与标准模板之间通过颜色距离计算的方法相匹配就可以检测出该元件的颜色。

Color Detection Method for Gas Generator of Safety Belt Based on Machine Vision

The purpose was to measure the color of safety belt’ s gas generator by the method of machine vision. First, color CCD camera was use to get the color images of the components. Then the software ( NI LabVIEW) was used to process those images easily. The color cast adjustment of those images and image filtering were made to get the desired images. Then the color values of different gas generators were saved as standard templates. The values of the template were matched with the detecting members to determine the com?ponent’ s color.
