Binocular Stereovision-based Security Vehicles Spacing Survey Technology

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.
