Example Embodiment

[0066] Example 1

[0067] Reference Figure 1~Figure 7 , A vehicle red light behavior detection device based on machine vision with monocular and multiple detection surfaces. The working principle diagram of the vehicle red light behavior detection device based on machine vision with monocular and multiple detection surfaces is attached. figure 2 As shown; the vehicle red light running behavior detection device includes a microprocessor, a monitoring sensor used to monitor road junctions, the microprocessor includes: image data reading and preprocessing module, used to read from the monitoring sensor The transmitted video image information is preprocessed for the video image information; virtual detection line setting, traffic light detection area setting, lane customization, lane and signal light association customization module, used to customize the virtual parking line of the lane, and customize the traffic signal light The detection area, the lane on the customized road, th...

Example Embodiment

[0095] Example 2

[0096] Reference Figure 1~Figure 7 , The rest is the same as the first embodiment, the difference is that the auxiliary light is used. In the case of insufficient light at the intersection, in order to capture the high-quality license plate image and the face image on the driver’s seat, the present invention captures the first position , The second position and the third position use pulsed light from a narrow pulse generator for flash auxiliary lighting. The flash auxiliary lighting is controlled by a microprocessor. The flash auxiliary lighting is activated at the same time during the capture action, and the pulsed light flash continues The time is a few tenths of the duration of the general flash. The flash auxiliary lighting is installed near the monocular multi-detection surface camera, and the flash lighting light is projected toward the direction of the intersection stop line. The irritation of the flash lighting to the driver’s eyes is negligible, but...

Abstract

A detection device for behaviors of running the red light of a vehicle based on machine vision with a single eye and multiple detection faces comprises a microprocessor and a monitoring sensor, wherein the monitoring sensor is used for monitoring road conditions. The monitoring sensor is a high definition camera with the single eye and the multiple detection faces. The high definition camera with the single eye and the multiple detection faces is used for shooting signal lamps and an image relative to the signal lamps and of the vehicle running the red light near a stop mark of a road. An image processing technique is used for identification of the states of the traffic signal lamps and the motion states of the vehicle near the stop mark. The behaviors of running the red light of the vehicle are automatically judged according to relevant laws and regulations of the state, and illegal parking recordings and relevant evidence materials are automatically generated. The detection device for the behaviors of running the red light of the vehicle based on the machine vision with the single eye and the multiple detection faces is accurate in detection, convenient to maintain and install, and complete in evidence obtaining of rule and regulation breaking behaviors.

Description

technical field [0001] The invention relates to a vehicle red light running behavior detection device, which effectively and comprehensively applies machine vision technology, image processing technology, data communication technology, computer network technology, etc. to traffic violation management, and is especially suitable for electronic police who specialize in detecting and processing red light running behavior. Background technique [0002] With the rapid development of the economy, the number of vehicles has increased sharply, resulting in increasingly serious traffic problems, such as the deterioration of the traffic environment, frequent traffic accidents, traffic congestion, etc., especially in Beijing, Shanghai and other medium and large cities, the traffic situation is showing a worsening trend , the annual death toll of traffic accidents in my country is basically at the level of about 100,000 people, ranking first in the world for several consecutive years. In...
