摘要：Braking performance plays a vital role for the safety in vehicle operation, so the measurement of braking performance is very important. In this article, an automatic measurement method for braking performance measurement using binocu?lar stereo vision is proposed in order to obtain the vehicle’s braking trajectory and other performance characteristics in real time. First, this article describes the principles of stereo vision in the context of measuring vehicle braking perfor?mance. Then, it focuses on image processing algorithm for stereo vision and the three-dimensional reconstruction algo?rithm. Finally, the reliability of the measurement system is verified through multiple sets of real vehicle experiments on different car models. The results show that the proposed vehicle braking performance measurement system can per?form automated and non-contact measurements. The detection system presented in this article has good detection accuracy and repeatability, and its detection time is short, so it can meet the needs of vehicle online testing.
