Embodiment Construction
[0030] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and provides a detailed implementation manner and a specific operation process, but the protection scope of the present invention is not limited to the following implementation. example.
[0031] see figure 1 and figure 2 , an unfastened seatbelt behavior detection system based on in-vehicle video analysis, comprising a video processing unit and a signal transmission control unit. The video processing unit includes an in-vehicle video capture unit, an in-vehicle DSP behavior analysis unit and an in-vehicle control unit. The in-vehicle video capture unit is an in-vehicle camera placed at the front end of the vehicle, and the in-vehicle camera is signal-connected to the in-vehicle DSP behavior analysis unit. The car camera has a built-in MV-1394 video capture card.
[0032] The vehicle-mounted DSP be...

The invention discloses a safety belt unfastening behavior detection method based on vehicular video analysis. A vehicular control unit detects the movement condition of a vehicle in real time and triggers a vehicular video unit to acquire dynamic video information after discovering vehicle movement, a position area of a driver is delimited after image preprocessing, safety belt wearing target characteristics are locked, a DSP (digital signal processor) video analysis procedure is started, a safety belt unfastening behavior of the driver is discovered, a vehicular alarm module is started, and information is transmitted to a remote supervision center platform through a remote transmission module. An image frame difference algorithm analyzes and detects the change of a dynamic video image in real time, image sequences without obvious or special change are identified and removed, dynamic behaviors and background differences of image sequences with obvious movement or dynamic change are identified, the behavior whether the driver wears a safety belt in driving or not is confirmed through a gray integral projection algorithm, and the safety belt unfastening behavior detection method is high in detection accuracy and rapid in detection.
Description
technical field [0001] The invention relates to the field of analysis and processing of dynamic images, in particular to a method for detecting unfastened seat belt behavior based on vehicle-mounted video analysis. Background technique [0002] The scope of video surveillance image processing technology is very wide. In the past, it mainly studied the digitization and networking of surveillance images, and improved the functions of surveillance image interconnection, information sharing, and remote monitoring. [0003] With the rapid increase of security, technical defense, and traffic monitoring systems in large and medium-sized cities in my country in recent years, the number of surveillance videos has exploded. Image data is almost impossible. [0004] At present, the traditional seat belt detection method in my country's market is the use of on-board electronic detection. Many drivers can "deceive" the device by directly buckling the seat belt into the detection device, ...
