摘　　要：基于双目立体视觉原理,提出了一种安全车辆间距测量方案。该系统根据目标车辆在左右摄像头所获得的立体图像对应的不同坐标,计算出目标车辆到摄像头的距离。试验结果表明,该测距方案测量精度高、测量范围广,能满足智能交通中车辆安全距离测量的实际需要,是一种有效的前方车距测量方案。本文的研究方法,同样适用于对车辆前方其他目标物的距离测量。Based on the principle of binocular stereovision, a security vehicles spacing survey measurement program was proposed. According to the target vehicle in the camera around a binocular images obtained on the different coordinates, the system calculated the distance between the target vehicle and the camera. The test results show that the measurement program is an effective one from the front car in that the high precision and the wide measurement range of the program meet the needs of intelligent transportation vehicles in a security vehicles spacing survey. This research method is equally applicable to vehicles in front of the other targets of distance measurement.
