Description
Technical field
The present invention relates to lane change alarm sets, more particularly to based on the lane change alarm set of stereopsis ranging and its side
Method.
Background technique
In vehicle travel process, vehicle lane change is common situation, and for new hand driver, tight due to upper road
It opens so that increasing risk, car accident incidence is very high, and forms three-dimensional shadow by polarisation principle during lane change
The mode of picture is shown on middle control screen, this mode can be improved safety of vehicle during lane change, and in lane change
Cheng Zhong, road conditions for observing vehicle-surroundings that can be visual and clear improve the safety of driving.
Traditional automobile lane change alarm set is not that can not pass through three-dimensional shadow by stereopsis acquisition and displaying principle
Monitoring as realizing vehicle-surroundings road conditions, it is not high to the judgement precision of vehicle-surroundings road conditions, it, can not be automatic in vehicle travel process
Ranging, monitoring relative velocity or acceleration, be easy to cause the generation of accident, not very practical.
Summary of the invention

When without lane change condition, voice or light intelligent reminding.
In a preferred embodiment of the present invention, light compensating lamp is provided on the camera in step (2).
In a preferred embodiment of the present invention, the luggage carrier is H-type structure.
The invention solves the defect existing in the background technology, the present invention have it is following the utility model has the advantages that
(1) by two cameras, there are spacing, and two different cameras is made to shoot two images with parallax,
Then right and left eyes are presented respectively to and form stereopsis, stereopsis contains the depth information of periphery scenery, makes eyes to week
The sense organ of side things is truer, make one more easily between accurate judgement periphery road conditions and vehicle and nearby vehicle away from
From.
(2) any one group of matching of stereopsis carries out stereoscopic rangefinding, and vehicle's surroundings barrier can be measured after being calculated
Relative distance, speed, acceleration between distance and vehicle and nearby vehicle, to realize intellectual monitoring, remind.
(3) several cameras can be moved flexibly, and by adjusting the distance between adjacent camera, two cameras are clapped
Parallax between two pictures taken the photograph generates variation, so as to 360 degree of detection vehicle periphery information, improves the safety of lane change
Property.
(4) when monitoring vehicle peripheral information without lane change condition by stereopsis, voice or light intelligent reminding,
Warning driver not carry out lane change operation, improve drive safety.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the partial schematic diagram of the preferred embodiment of the present invention；
In figure:
1, luggage carrier, 2, track, 3, camera, 4, focus point.
Specific embodiment
Presently in connection with drawings and examples, the present invention is described in further detail, these attached drawings are simplified signal
Figure, the basic structure of the invention will be illustrated schematically only, therefore it only shows the composition relevant to the invention.
As shown in Figure 1, the lane change alarm set based on stereopsis ranging, comprising: luggage carrier 1 is mounted in luggage carrier 1
The camera 3 in portion forms.
Specifically, the luggage carrier 1 is hollow transparent structure, the inside of 1 two sides of luggage carrier along its length is set
It is equipped with track 2, several cameras 3 are arranged at intervals on the track 2, the camera 3 can be moved along track 2；It is adjacent
Wantonly two camera 3 is one group of detection part, and any detection part passes through the different images that camera 3 detects, is capable of forming three-dimensional shadow
Picture in vehicle travel process, by stereopsis automatic range, monitors relative velocity or acceleration, during stereopsis is transmitted to
Road conditions can be observed on control screen and remind whether driver has lane change condition.
Further, in vehicle travel process, by stereopsis automatic range, relative velocity or acceleration are monitored, according to
By two cameras 3, there are spacing, so that two different cameras 3 is shot two images with parallax, are then in respectively
Stereopsis now is formed to right and left eyes, stereopsis contains the depth information of periphery scenery, makes sense of the eyes to periphery things
Official is truer, makes one more easily accurate judgement periphery road conditions and the distance between vehicle and nearby vehicle.
Any one group of matching of stereopsis carries out stereoscopic rangefinding, can be measured after being calculated vehicle's surroundings barrier away from
From and relative distance, speed, acceleration between vehicle and nearby vehicle, to realize intellectual monitoring, remind.
The camera 3 is the infrared camera 3 of 360 degree of acquisition images, and the spacing between each camera 3 can be adjusted
Whole, stereopsis transmits a signal to middle control by signal transmission device and shields, and becomes when observing that vehicle does not have by stereopsis
When road condition, voice or light intelligent reminding.
In order to achieve the above objectives, a kind of another technical solution that the present invention uses are as follows: user of lane change alarm set
Method, steps are as follows:
(1) luggage carrier 1 being mounted on automobile top, be screwed, the camera 3 installed on guide rail is individually moved,
Adjacent wantonly two camera 3 forms one group；
(2) one groups of cameras 3 shoot two images with parallax using different viewpoints, and two images pass through solid
The mode of display is presented to right and left eyes, forms stereopsis；
(3) in 3 moving process of camera, during changing with the spacing between two cameras 3, two are taken the photograph
The parallax between two pictures shot as first 3 generates variation, and the stereopsis of formation also changes therewith, can observe more
View stereo image；
(4) stereopsis is transmitted to middle control by signal transmission device and shields, and can intuitively observe vehicle-surroundings information, when
When without lane change condition, voice or light intelligent reminding.
Further, several cameras 3 can be moved flexibly, by adjusting the distance between adjacent camera 3, two
The parallax between two pictures that camera 3 is shot generates variation, so as to 360 degree of detection vehicle periphery information, improves and becomes
The safety in road, camera 3 divide for both of which, are respectively placed in parallel and convergence type, when two 3 shooting pictures of camera have
When having coincidence point, two cameras 3 are focused in same depth location, this position or point overlapping form focus point 4, as ignore
Difference, if being exactly just to present on the screen on a display screen, the scenery of other positions is presented on before screen and after screen, shape respectively
At stereopsis, vehicle periphery barrier can intuitively be observed by stereopsis, and being capable of automatic measurement barrier
The distance between vehicle, then according to the speed per hour of vehicle, acceleration and vehicle and barrier or periphery
Relative velocity between vehicle judge vehicle at a distance from barrier or nearby vehicle, so as to recognize whether to have
There is lane change condition.
It is provided with light compensating lamp on camera 3 in step (2), the luggage carrier 1 is H-type structure, when passing through stereopsis
When monitoring vehicle peripheral information without lane change condition, voice or light intelligent reminding, warning driver not carry out lane change
Operation improves drive safety.
Based on the above description of the preferred embodiments of the present invention, through the above description, related personnel completely can be with
Without departing from the scope of the technological thought of the present invention', various changes and amendments are carried out.The technical scope of this invention
It is not limited to the contents of the specification, it is necessary to determine the technical scope according to the scope of the claims.
