Research on Vehicle Dimensional Measurement Based on Machine Vision

Abstract

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 were 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 was presented. The test results show that the system achieves the automatic, fast and accurate measurement of vehicle dimensions.
