1. A single-camera system for measuring a vehicle distance, comprising a variable-magnification single-camera module (2), an operational control module (3) and an infrared emission module (4), characterized in that said operational control module (3) is respectively connected with the variable-magnification single-camera module (2) and the infrared emission module (4);

  • said variable-magnification single-camera module (2) 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(6);

    said operational control module (3) is used for obtaining the position information of the highlight speckle outputted by the variable-magnification single-camera module (2) and the number of the pixels occupied by the width/height of the vehicle license plate (6), and computing a vehicle distance according to a geometrical relationship and an averaging algorithm; and

    said infrared emission module (4) is used for receiving a control command of the operational control module (3) to enable and emit an infrared light beam and close the infrared light beam.
