The invention discloses a recognition system for a safe driving behavior based on a vehicle-mounted intelligent terminal. The system includes vehicle-mounted equipment, an interface system and a back-end data base; and the vehicle-mounted equipment comprises a high-definition camera and a vehicle-mounted intelligent terminal, wherein the high-definition camera is connected with the vehicle-mountedintelligent terminal, the vehicle-mounted intelligent terminal is connected with the interface system, and the interface system is connected with the back-end data base. Compared with traditional safe driving recognition systems, after a facial area image or video of a driver is collected through the high-definition camera, the system can achieve processing analysis of the images and the video locally in the vehicle-mounted intelligent terminal, determines whether the driver has a dangerous driving behavior, reports a result to the back-end data base through the interface system, is very small in bandwidth requirement, can normally perform an alarm function even in the absence of a network, is strong in anti-interference capability, can monitor and alarm more effectively the dangerous driving behavior, and enables bad driving habits of the driver to be corrected.
