Monocular camera (imager) high beam normally-open detection device based on double different bases

Abstract

The invention discloses a monocular camera (imager) high beam normally-open detection device based on double different bases, and belongs to the field of communication and transportation signal control equipment. According to the device, the irradiation angle of a vehicle high beam is utilized, and a high beam normally-open light detection unit composed of a monocular camera of a fixed base and a monocular camera which is mounted on an adjustable base and can be steplessly adjusted is mounted on a detection cross rod. According to presetting, when the vehicle with the high beam turned on passes through a distance detection point, lamplight of the vehicle with the high beam turned on irradiates on the monocular camera, a sensitive element on the monocular camera is triggered, and the monocular camera shoots the license plate number of the corresponding vehicle. Meanwhile, the monocular camera mounted on the adjustable base is started, and the vertical inclination angle between the monocular camera and the cross rod is adjusted in a stepless mode to achieve tracking camera shooting of the same vehicle with the high beam till the vehicle passes through the next detection point. Pictures shot by the two monocular cameras (imagers) are transmitted to background equipment to serve as a judgment basis. The device has the characteristics of no algorithm, low development cost, accurate discrimination and the like.

Description

technical field [0001] The invention relates to the field of transportation signal control equipment. Specifically, it is a device for detecting whether the high beam of a vehicle is always on for a monocular camera based on two different bases. Background technique [0002] The "Regulations for the Implementation of the Road Traffic Safety Law" stipulates that motor vehicles shall not use high beams in the following situations: [0003] 1. When meeting vehicles at night on a road without central isolation facilities or without a central line, low-beam lights should be used instead of 150 meters away from vehicles coming from the opposite direction; [0004] 2. Low beams should be used when there is no central isolation facility or a narrow bridge or narrow road without a central line meets non-motorized vehicles; [0005] 3. When passing through an intersection controlled by traffic signals, high beams cannot be used when turning; [0006] 4. When driving at night withou...

AI Technical Summary

Problems solved by technology

[0005] 3. When passing through an intersection controlled by traffic signals, high beams cannot be used when turning;

[0006] 4. When driving at night without street lights, poor lighting, or low visibility such as fog, rain, snow, sand, etc., when the rear vehicle driving in the same direction and the vehicle in front are driving at close distances, high beams cannot be used;

[0008] 6. High beams should not be used in well-lit urban areas
