Embodiment Construction

[0011] Such as figure 1 As shown, the green marking laser module is placed directly in front of the car, and the laser line projected on the ground is perpendicular to the driving direction of the car, and intersects the traffic markings on both sides at 0.5 to 1 meter in front of the car. The linear array CCD camera The input module is installed in the center of the front of the car. The lens of the line array CCD camera is a cylindrical lens. By adjusting the camera angle of the line array CCD camera relative to the ground, the laser marking line can be clearly observed in the field of view. , due to the great contrast between the traffic markings drawn on the road and the road itself, the imaging contrast of them on the line array CCD camera is also very large. Driven by driving pulses, the signals are sequentially output through the shift register, and the signals can be passed through the comparator. Distinguish the high-contrast image generated by traffic markings, and o...

Abstract

The invention provides a road traffic markings auto-identification reminder for motor vehicles and belongs to the fields of optics, electronics, photoelectric surveying and the like. The road traffic markings auto-identification reminder for motor vehicles comprises a green marking laser module, a linear array CCD photography input module, a high-speed signal processing module, and a motor vehicle traffic marking crossing prompt module. The green marking laser module and the linear array CCD photography input module are mounted at the front of a vehicle. The high-speed signal processing module and the motor vehicle traffic marking crossing prompt module are mounted inside the vehicle. The data output end of the linear array CCD photography input module is connected with the data input end of the high-speed signal processing module. The output end of the high-speed signal processing module is connected with the data input end of the motor vehicle traffic marking crossing prompt module. The road traffic markings auto-identification reminder for motor vehicles judges whether the motor vehicle strays off the traffic marking or not according to the signals of road traffic markings, and sending out prompt messages once the motor vehicle strays off the traffic marking, thus certain guarantee is provided for driving safety and avoidance of traffic violations.

Description

technical field [0001] The invention belongs to the fields of optics, electronics, photoelectric measurement, etc., and uses photoelectric detection technology to detect road traffic markings in real time and prompt motor vehicle drivers in time for possible deviations. Background technique [0002] There are some devices that use photoelectric detection technology to measure position deviation in the past technology or the market, but the general products or technologies are difficult to meet the speed of motor vehicles, test range, and detection objects in terms of signal processing speed, measurement area range, and cost. Require. Contents of the invention [0003] The object of the present invention is to provide a photoelectric high-speed detection device based on a green marking laser and a high-speed linear array CCD camera. The projection of the laser line on the road surface has a large contrast between the traffic markings drawn on the road surface and the road ...
