Auxiliary application of vehicle machine vision technology in the field of traffic safety

In recent years, the important role that machine vision technology can play in the security field has been continuously highlighted, making it a better technical means that can replace or serve as a human eye. Traffic safety has always been an important branch in the field of safety. Especially in today's social background where the surge in vehicles has caused excessive traffic pressure on the road, how to effectively solve traffic safety issues is imminent, and machine vision technology naturally plays a role in it. .
 Intelligent transportation system is a more common and representative application of machine vision technology in the field of traffic safety. By establishing a digital monitoring network covering the main roads and intersections in cities, the machine vision system can be used to accurately image the vehicle operating conditions at traffic intersections, and real-time The image information is transmitted to the dispatch center to realize the monitoring of the running status of road vehicles. In addition, in-vehicle machine vision technology is also one of the applications that have gradually developed in recent years. It provides appropriate driving assistance for various physical conditions and visual defects in the human eye.

Visual enhancement applications
The vision enhancement system can enhance the driver's visual ability at different times according to different weather conditions. With the help of machine vision technology, sensors such as CCD, infrared sensor, vehicle speed sensor, GPS and millimeter wave radar are used to obtain road information, and image processing software is used to transmit and process information to extract useful information about the traffic environment under low visibility and low illumination. The noise is eliminated, and it is provided to the driver in the form of images in a short period of time to improve the safety of the vehicle.
 Vehicle pedestrian detection application
Vehicle detection system With the help of machine vision technology, various sensors can be used to detect relevant information of surrounding vehicles, including front and rear vehicle speed, position, and the size and position of obstacles. The pedestrian detection system is also applied based on the same principle, and the position of the pedestrian is detected by machine vision technology.
 Fatigue monitoring application
In the current research on driving fatigue inspection monitoring systems, vehicle-mounted machine vision systems are often used to monitor human posture and operating behaviors, and judge fatigue status based on system feedback information. When the driver is in a state of fatigue, the driver is stimulated by sound, light, vibration, etc. to restore his awake state. To a certain extent, traffic accidents caused by driver fatigue have been greatly reduced.
 There are many more auxiliary applications of vehicle machine vision technology in the field of traffic safety, which are not listed here one by one. Of course, no matter how powerful the in-vehicle machine vision technology is in the application, choosing high-quality machine vision components is a basic prerequisite.
