Description
Technical field
The utility model relates to automobile auxiliary security or automatic Pilot field, is specifically related to a kind of road barricade means of identification.
Background technology
One of automatic driving technical issues that need to address are road Identification problems, and the technological means that prior art adopts has image recognition, infrared pickoff identification and radar identification.These technology are long-range by electronic chart and GPS programme path, catch the obstacles such as vehicle, pedestrian, traffic lights and direction board, and calculate distance by radar near vehicle by pick up camera and infrared pickoff.The defect of prior art is, no matter above-mentioned which kind of recognition technology, and all identical or close projection and grooves of some colors on None-identified road surface, in the time there are these unfairness road conditions in vehicle course, vehicle can not be hidden, thereby affects traffic safety.
Utility model content
In view of this, a kind of road barricade means of identification that the utility model provides, can effectively identify projection and groove on road.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of road barricade means of identification, this means of identification comprises:
Be installed on headstock, for layout being projected to the laser beam emitting device on the front road surface of car;
Be installed on headstock, for catching the image capture device of laser real-time pattern on the front road surface of car;
And, accept the data that image capture device transmits, analyze layout and real-time pattern the treater to automatic vehicle control system by analysis result real-time Transmission.By the difference between contrast design pattern and real-time pattern, can obtain certain region, front is projection or groove, the route running of degree minimum thereby the selection of commander's automobile is jolted.
Preferably, laser beam emitting device is laser projecting apparatus, and image capture device is pick up camera.The equipment that other have above-mentioned functions of the prior art all can.
Further, laser beam emitting device and image capture device are all installed on headstock inside by angle regulator.Before making laser beam emitting device and image capture device can select car, road surface how far is for projection road surface, to meet different condition of road surfaces and Vehicle Speed.
A kind of road barricade recognition methods, comprises the following steps:
401, laser layout is projected on the front road surface of car;
402, catch the laser real-time pattern on the front road surface of car;
403, analyze layout and real-time pattern and analysis result is transferred to automatic vehicle control system.
Preferably, in step 401, layout is spot figure or grid chart.More easily analyze and distinguish.
Preferably, in step 401, laser is black light.That while avoiding passenger to hope to road surface, can not remove sees road surface clearly.
The beneficial effects of the utility model are: the condition of road surface before real-time analysis car, obtains the obstacle that may cause traffic safety, guarantee driving safety.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described, obviously, accompanying drawing is described is only a part of the present utility model instead of whole embodiment.
As illustrated in fig. 1 and 2, a kind of road barricade means of identification that the utility model provides, this means of identification comprises and is installed on headstock, for layout being projected to the laser beam emitting device 1 on the front road surface of car; Be installed on headstock, for catching the image capture device 2 of laser real-time pattern on the front road surface of car; And, accept the data that image capture device 2 transmits, analyze layout and real-time pattern the treater 3 to automatic vehicle control system by analysis result real-time Transmission.Here, refer to can be to projection full-view front position, road surface before laser beam emitting device 1 and image capture device 2 cars for headstock.
Laser beam emitting device 1 and image capture device 2 are preferably mounted at headstock inside so that protect and strengthen car body aesthetic feeling, but should be without barrier between the catch end of the transmitting terminal of laser beam emitting device 1 and image capture device 2 and road surface.
The in the situation that of known laser feedway 1 setting height(from bottom) and crevice projection angle, if the front road surface of car is complete plane, the laser real-time pattern forming after layout projection is so unique with computable.After projection, image capture device 2 catches and is transferred to treater 3 by laser real-time pattern, and what treater 3 should contrast in the time of contrast is actual laser real-time pattern and theoretic laser real-time pattern.As shown in Figure 3 and Figure 4, in the time there is projection and groove on road surface, actual real-time pattern can deform, now, and according to the size of distortion, and aforesaid laser beam emitting device 1 setting height(from bottom) and crevice projection angle, according to geometric knowledge, can draw projection and the size of groove, personal vehicle system is again in conjunction with the moving velocity of vehicle, can control accurately vehicle avoiding obstacles, guarantee driving safety.Obviously, for ascents and descents, the utility model also has discernibility.
In order to change the time to the enough route of vehicle, when road conditions better, when the speed of a motor vehicle is very fast, for example, on expressway, preferably by laser projection to longer-distance road surface.And on the poor road of the road conditions such as back road, select to be incident upon on the road surface by vehicle closer distance, therefore, laser beam emitting device 1 and image capture device 2 should be that angle is adjustable and can automatically control.It should be noted that, laser beam emitting device 1 is in different angles simultaneously, and identical layout should present different theoretical real-time patterns, and treater 3 is synchronous this pattern that upgrades in regulating laser beam emitting device 1 and image capture device 2.
In the selection of concrete layout, preferably spot figure and grid chart, concrete pattern should consider the setting height(from bottom) of laser beam emitting device 1 and the size of crevice projection angle and vehicle tyre on selecting, to guarantee, in the time of projection distance farthest, the projection and the groove that are enough to affect passenger safety should be able to detect by arbitrary secondary real-time pattern, and therefore, the blank parts of real-time pattern should be not excessive.
The road barricade recognition methods that the utility model provides, comprises the following steps:
401, laser layout is projected on the front road surface of car;
402, catch the laser real-time pattern on the front road surface of car;
403, analyze layout and real-time pattern and analysis result is transferred to automatic vehicle control system.
In order to ensure that passenger checks the accuracy of front road conditions, preferably project black light, as ultraviolet ray, infrared ray, far-infrared rays etc.
The road barricade means of identification that the utility model provides, is preferably used in conjunction with other existing road obstacle means of identification when actual use, jointly to complete the auxiliary function of driving.
Except automobile, the utility model is also applicable to other the prior art field that need to identify road barricade.
The description of technique scheme has only embodied optimal technical scheme of the present utility model, and is not exhaustively, or the utility model is limited to disclosed form.Based on embodiment of the present utility model, the other forms of technical scheme that anyone obtains under the prerequisite of not making creative work, though its in structure or make in form which kind of change, within all belonging to protection domain of the present utility model.
