摘　　要：使用彩色图像的彩色分割技术,开发了一套基于机器视觉的汽车整车尺寸测量系统。论述了该系统组成、测量原理及方法,针对复杂背景的彩色图像,提出利用初始轮廓线逐渐逼近最佳图像边缘,让图像轮廓的整体信息参与分类过程,有效地克服了噪声影响,同时又不损失图像的边缘信息,提高了图像边缘的检测精度和分割的质量。试验结果表明,该系统可以实现汽车整车尺寸的自动、快速、准确测量。To present a measurement system of vehicle-body dimensions based on machine vision with the application of technique of color segmentation based on color image. The construction of the system, the measurement principle and methods are discussed. To improve the quality of the precision of edge detection and image segmentation, a method of edge extraction by use of initializing contour line for color image is presented.The test results show that the system achieves the automatic, fast and accurate testing of vehicle dimensions the measurement result.
