The invention discloses a machine vision based headlamp follow-up steering control method. The machine vision based headlamp follow-up steering control method comprises the following steps of fixing a vehicle-mounted camera on the central axis of a vehicle to acquire images, fixing a sensor group on the edge of the camera, installing ranging radars on the front side, rear side, left side and right side of the vehicle, installing a camera on one side of each radar, utilizing a mean value method to perform background modeling, converting all frames of images in acquired video data into gray level images, conducting differential operation on the gray level images and corresponding modeling background, conducting filtering processing on differential images to remove noise, utilizing preset threshold values to detect the differential images and determining a turning angel of a headlamp through a central processor. The machine vision based headlamp follow-up steering control method utilizes machine vision to replace a driver to sense the front road situation, achieves active control on headlamp turning, instead of passive control. Mean values serve as pixel gray values of background images, and control accuracy is further improved.
