Abstract
A kind of avoidance prior-warning device and determination methods, belong to technical field of vehicle safety.The avoidance prior-warning device includes：Power module, processor module, camera module, image processing module, warning module, memory module and wireless module.Avoidance method for early warning is：According to physics of photography, same object is before same camera lens, and it is bigger than the picture area accounted for apart from the imaging of camera lens far object that the image objects near apart from camera lens account for picture area；Picture area ratio is accounted for come the distance of disturbance in judgement thing and camera lens by the barrier imaging in picture.A kind of avoidance prior-warning device of the present invention and determination methods are to go the distance of disturbance in judgement thing and camera lens based on optical photography principle so as to send early warning, and the probability of traffic accident occurs for reduction driver, improves the security of driver driving vehicle.
Description
Technical field
A kind of avoidance prior-warning device and determination methods, belong to technical field of vehicle safety, more particularly to a kind of avoidance early warning
Device and determination methods.
Background technology
With the progress of society and continuing to develop for automobile industry, automobile is increasingly becoming the main means of transport of trip, I
Increasingly be unable to do without automobile, vehicle is more and more, and vehicle jam is increasingly common on road, the traffic accident frequency of occurrences
Also therefore more and more higher, so traffic safety also turns into our urgent problems.
The content of the invention
The invention aims to the deficiency solved the above problems, a kind of avoidance prior-warning device and determination methods are invented.
A kind of avoidance prior-warning device, including power module, processor module, camera module, image processing module, early warning
Module, memory module and wireless module；Power module is other each module for power supply；Camera module is used to gather image letter
Breath；The image information that image processing module is used to collect camera is handled, and analyzes the situation of change of image；Processor
Module is used to calculate processing image change situation, chooses barrier to be imaged and account for the ratio of picture area to barrier and counts
Calculate, and control other modules to work, when result accounts for image area for barrier becomes big, warning module sends early warning and carried
Show；Wireless module is connected for launching wireless signal with mobile terminal；Memory module is used to store the letter that camera is collected
The processing data of breath and processor.
A kind of determination methods of avoidance early warning：According to physics of photography, same object is near apart from camera lens before same camera lens
It is bigger than the picture area accounted for apart from the imaging of camera lens far object that image objects account for picture area；It is imaged by the barrier in picture
Account for the distance that picture area ratio comes disturbance in judgement thing and camera lens.First pictures are successively obtained by video camera, by processor
Module is analyzed and processed to the first pictures and chooses barrier to be imaged；Continue track up barrier and draw the second pictures
And calculate it and account for picture area ratio and compared with the area ratio of first, if result become it is big if disturbance in judgement thing apart from mirror
Head is near, and now avoidance prior-warning device just sends avoidance early warning.If result is smaller than the first pictures, disturbance in judgement thing distance
Camera lens becomes remote, at this moment then reselects barrier.
The mobile terminal includes mobile phone, for checking that obstacle distance and video camera photograph various information.
A kind of avoidance prior-warning device of the present invention and determination methods are to remove disturbance in judgement thing and camera lens based on optical photography principle
Distance so as to send early warning, the possibility of traffic accident occurs for reduction driver, improves the security of driver driving vehicle.
Brief description of the drawings
Accompanying drawing 1 is a kind of avoidance prior-warning device structured flowchart of the invention；Accompanying drawing 2 is a kind of avoidance early warning judgement side of the invention
The flow chart of method.
In figure, power module, processor module, camera module, image processing module, warning module, memory module,
Wireless module, mobile phone terminal；Image is obtained, and selectes barrier imaging, calculates the area ratio value of the shared image of barrier imaging,
Contrasted with last time ratio value, ratio is small, ratio is big, occur warning and indicate.
Embodiment
The present invention is illustrated in conjunction with accompanying drawing, a kind of avoidance prior-warning device, including power module, processor die
Block, camera module, image processing module, warning module, memory module, wireless module and mobile phone terminal.Power module is
Other each module for power supply；Camera module, for gathering image information；Image processing module, for collect camera
Image information is handled, and analyzes the situation of change of image；Processor module, for calculating processing image change situation, chooses
Barrier is imaged and accounts for picture area ratio to it and calculates, and controls other modules to work；Warning module, for when processing knot
Fruit accounts for image area for barrier and becomes big, now sends early warning；Wireless module, for launching wireless signal and mobile phone terminal
Connection；Memory module, the processing data for storing information that camera collects and processor.
A kind of determination methods of avoidance early warning, are realized by above-mentioned avoidance prior-warning device, comprised the concrete steps that：Shooting
Head module successively gets the first pictures and the second pictures；Second pictures and the first pictures are carried out at graphical analysis
Reason, if obstacle target area accounts for the second pictures area ratio and accounted for than obstacle target area in the first pictures in the second pictures
First pictures area ratio is big, then chooses the obstacle target area in the second pictures to be imaged for barrier；Continue to track and clap
Take the photograph the barrier and obtain the 3rd pictures, and the 3rd pictures area ratio is accounted for barrier imaging and carry out analysis calculating, if knot
Fruit is bigger than the accounting of the second pictures, then judges that the obstacle distance camera lens is more and more nearer, at this moment send avoiding obstacles early warning
Signal；If obstacle target area accounts for the second pictures area ratio than obstacle target area in the first pictures in the second pictures
The first pictures area ratio is accounted for small, if or obstacle target area accounts for the 3rd pictures area ratio and compares in the 3rd pictures
To account for the second pictures area ratio small for obstacle target area in two pictures, then disturbance in judgement thing becomes remote apart from camera lens, at this moment then
Reselect barrier.
A kind of avoidance prior-warning device of the present invention and determination methods are to remove disturbance in judgement thing and camera lens based on optical photography principle
Distance so as to send early warning, reduce the probability that traffic accident occurs for driver, improve the security of driver driving vehicle.
