Abstract
The invention provides an automobile warning device. At present, a device which can automatically detect whether there are pedestrians around an automobile, especially in front of the automobile and can give out an anti-collision alarm according to the distance between the pedestrians and the automobile does not exist on the market. The automobile warning device comprises double-camera modules (1), loudspeakers (2) and a computer (3). The automobile warning device can protect the security of the pedestrians well and meanwhile prevent a driver from keeping honking a horn.
Description
Technical field
The present invention relates to the anticollision device of a kind of automobile to pedestrian.
Background technology
There is no on the market at present automatic detection motor vehicle environment pedestrian, send the equipment of collision-proof alarm simultaneously according to the distance of pedestrian and automobile, the present invention aims to provide a kind of device, can well protect pedestrains safety, avoids driver not stop blast the horn simultaneously.
Summary of the invention
A vehicle warning device, is characterized in that: comprise (1) dual camera module, (2) loud speaker, (3) computing machine.The data output on dual camera module is controlled and obtained to computing machine to dual camera module; Computer export prompt tone is to loud speaker.Dual camera module and loud speaker are installed in headstock both sides, and each is a set of for every side, and they are connected to same computer.Get in two pairs of dual camera modules separately near a camera in the middle of headstock, totally two, camera partners, computing machine is the distance from automobile according to this front lower place, middle road surface of judgement of parallax to camera automobile unique point, then calculates car speed according to the change of distance of unique point in the unit time.Computing machine is the distance from automobile according to surrounding's large sized object more than the parallax judgement dual camera module height of two cameras in dual camera module, when calculating object in automobile, computer starting human body recognizer, when judging, be that human body is when constantly near automobile, computing machine sends prompt tone to loud speaker, computer discovery when the speed of a motor vehicle was fast state at that time, sends the anxious alarm that stops to automobile middle control computer.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of vehicle warning device main assembly block scheme
The specific embodiment
Assembling: each fixes a dual camera module (1) automobile left front and right front direction, camera image sensor plane normal is parallel with ground, normal becomes 30 degree angles with the line of centers being linked to be before and after automobile, and two camera image center sensor lines parallel with ground (2) the dual camera module in dual camera module is linked computing machine (3) computing machine by USB line and is connected automobile middle control computer by CAN bus.
How to obtain front lower place, road surface unique point in the middle of automobile: get in two pairs of dual camera modules separately near a camera in the middle of headstock, totally two, camera partners.Calculate this to camera picture unique point separately after, the priori of utilizing two cameras substantially to have 1/3 picture to overlap is mated, obtain 3 distributions relatively uniformly strong unique point as final, participate in the unique point that distance is calculated.
How to judge large sized object: calculate after the strong unique point of camera picture, utilize the phase mutual edge distance of the same stack features point in unit time front and back and the displacement information in picture to judge.If displacement is remarkable, phase mutual edge distance changes less, can substantially be judged as so same object, if a stack features point is widely distributed at camera picture, can be judged as large object so.
How to judge that large sized object is approaching automobile: after the time difference, between the unique point of object, distance becomes large according to unit, represents that object is approaching automobile.
How to judge pedestrian: approach the unique point of car object, obtain object-by shape information.Whether according to shape information, investigate is strip shape, length and width size than whether between 2:1 to 10.Further judge that whether this strip shape CF is fairly regular, if fairly regular, be not pedestrian, otherwise think pedestrian.
If think pedestrian, and constantly approaching, computing machine sends prompt tone to loud speaker, reminds driver and pedestrian to take care.
When automobile is fast state, if find pedestrian, and constantly approach from automobile is positive, computing machine sends the anxious alarm that stops by CAN bus to automobile middle control computer.
Claims (5)
