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
The present invention belongs to the fields such as optics, electronics, photoelectric measurement, uses photoelectric detecting technology and detects in real time road traffic marking and to departing from of may occurring, in time point out automobile driver.
Background technology
There are some devices that utilize the photoelectric detecting technology measuring position to depart from technology in the past or the market, but general product or technology are in the requirement of the speed that is difficult to satisfy motor-driven vehicle going aspect conversion speed, measured zone scope, the cost, test area, detected object.
Summary of the invention
The purpose of this invention is to provide a kind of photoelectricity high-speed detection device based on green graticule laser and high speed linear array CCD pick up camera composition, this installs green graticule laser projection to the road surface of automobile direct of travel, take laser rays with the high speed linear array CCD pick up camera again and be incident upon projection on the road surface, because the own contrast of traffic marking and road surface of drawing on the road surface is very large, so their imaging contrasts on linear array CCD camera are also very large, driving by drive pulse, through the shift register sequence output signal, this signal can determine the hi gh contrast image that traffic marking produces by comparator, can obtain the position of hi gh contrast image in the visual field by pulse totalizer, because pick up camera is installed in the center of automobile, so by two hard contrast points relatively in the visual field asymmetric degree, can obtain the degree that self-propelled vehicle departs from traffic mark.
Hardware of the present invention is by the green graticule laser module that is installed in automotive front end, line array CCD shooting load module, and high speed signal processing module, the automobile traffic graticule that the is installed in automotive interior reminding module that crosses the border forms.
Technical scheme of the present invention is: comprise the green graticule laser module, the line array CCD shooting load module that are installed in automotive front end, high speed signal processing module, the automobile traffic graticule that the is installed in automotive interior reminding module that crosses the border, the data output end of line array CCD shooting load module connects the data input pin of high speed signal processing module, the cross the border data input pin of reminding module of the mouth junctor motor-car traffic marking of high speed signal processing module.Green graticule laser module is placed in the dead ahead of automobile, and the laser lines of projection are vertical with the direct of travel of automobile on the ground, and the traffic marking of 0.5 to 1 meter and both sides is crossing before automobile.Line array CCD shooting load module is installed in the center in the dead ahead of automobile, and the camera lens of linear array CCD camera is cylindrical lens, by adjusting the camera angle on the relative ground of linear array CCD camera, is as the criterion clearly observing straight line laser in the visual field.
The advantage that the present invention has is:
1. detecting speed of response is exceedingly fast.
2. with low cost, simple installation.
Description of drawings
Fig. 1 is block diagram of the present invention;
Fig. 2 is configuration schematic diagram of the present invention;
The specific embodiment
As shown in Figure 1, green graticule laser module is placed in the dead ahead of automobile, the laser lines of projection are vertical with the direct of travel of automobile on the ground, the traffic marking of 0.5 to 1 meter and both sides intersects before automobile, line array CCD shooting load module is installed in the center in the dead ahead of automobile, the camera lens of linear array CCD camera is cylindrical lens, by adjusting the camera angle on the relative ground of linear array CCD camera, be as the criterion in the visual field, clearly observing straight line laser, because the own contrast of traffic marking and road surface of drawing on the road surface is very large, so they on linear array CCD camera the imaging contrast also very large, drive by drive pulse, through the shift register sequence output signal, this signal can determine the hi gh contrast image that traffic marking produces by comparator, can obtain the position of hi gh contrast image in the visual field by pulse totalizer, because pick up camera is installed in the center of automobile, so by comparing the asymmetric degree of two hard contrast points, can obtain the degree that self-propelled vehicle departs from traffic mark, if depart from above setting value then reflected that automobile might line ball, sound or numeric display unit that the automobile traffic graticule crosses the border in the reminding module will be pointed out chaufeur.
Described green graticule laser module comprises green graticule laser, the line laser that sends, and luminance brightness is stronger, power 50-100 milliwatt.
Described line array CCD shooting load module, refer to: imaging device is high speed linear array CCD, cooperates the cylinder camera lens, resolution is 512 to 1024 pixels.
Described high speed signal processing module, can be realized by totally digital circuit, also can be realized by digital circuit matching embedded type treater, digital circuit is by the electric circuit constitutes such as impulse deviser, shift register, counting machine, memory device, comparators, drive by drive pulse, through the shift register sequence output signal, can determine the pixel intensity catastrophe point by comparator, by the pulse totalizer position of pixel in the visual field that can obtain suddenling change, if the alerting ability that cooperates microprocessor can the increase system to use.
The described automobile traffic graticule reminding module that crosses the border comprises: be used for amplifier and the loud speaker of auditory tone cues, the digital display of prompting departure degree.
As shown in Figure 2, being installed in the green graticule 1 that the green graticule laser module 3 on self-propelled vehicle 4 front ends launches is radiated on the road surface of motor-driven vehicle going, and cross with self-propelled vehicle both sides traffic marking 2 and 5, line array CCD shooting load module 6 takes the line array video camera visual field with green graticule 1, and the visual field planted agent comprises the both sides traffic marking.
Above one embodiment of the present of invention are had been described in detail, but described content only is preferred embodiment of the present invention, can not be considered to be used to limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., all should still belong within the patent covering scope of the present invention.
