The present invention discloses a single-camera system for measuring a vehicle distance and measurement method thereof. The single-camera system for measuring the vehicle distance comprises a variable-magnification single-camera module, an operational control module and an infrared emission module, wherein the operational control module is respectively connected with the variable-magnification single-camera module and the infrared emission module. The variable-magnification single-camera module is used for performing real-time video recording on a front scene, capturing the position information of a highlight speckle in a video image from a video and capturing the number of pixels occupied by the width/height of a vehicle license plate. The operational control module is used for obtaining the position information of the highlight speckle outputted by the variable-magnification single-camera module and the number of the pixels occupied by the width/height of the vehicle license plate, and computing a vehicle distance according to a geometrical relationship and an averaging algorithm. The present invention combines the video processing technology with the infrared control technology of a camera, enhances the measuring reliability of short distance of a vehicle, facilitates the usage, reduces the cost and can be widely applied to an active safety assisting system of the vehicle. |
