Embodiment
Embodiment 1
The present embodiment provides a kind of method for determining panoramic parking system demarcation opportunity, as shown in figure 1, including following step
Suddenly:
S101:The image of different visual angles environment around registration of vehicle is obtained, wherein the image tool of record adjacent view environment
There is overlapping region;As shown in Fig. 2 by taking four cameras as an example, the image of vehicle periphery different visual angles environment includes:Registration of vehicle
First image 201 in forward sight square ring border, the second image 202 of registration of vehicle LOOK RIGHT environment, registration of vehicle back angle environment
3rd image 203, the 4th image 204 of registration of vehicle LOOK LEFT environment.Wherein, the first image 201 and the second image 202 have
Overlapping region A, the second image 202 and the 3rd image 203 have overlapping region B, and the 3rd image 203 and the 4th image 204 have
Overlapping region C, the 4th image 204 and the first image 201 have overlapping region D.Before vehicle release, to panoramic parking system
After being demarcated, position of the overlapping region in each image, the pixel set occupied just turn into Given information.If take the photograph
As head quantity increased, its principle is similar to the principle in the present embodiment, and the image of adjacent two visual angle environment must have overlapping
Region, it is only possible to obtain complete panoramic view after stitching image.
S102:Judge in two images corresponding to adjacent view environment, whether the deviation of the image of overlapping region exceedes
Set deviation threshold, if then entering step S103, otherwise return to step S101.Under normal circumstances, panoramic parking system is demarcated
After completion, four width images in Fig. 2 should be able to be realized seamless spliced, obtain the panoramic view of vehicle-periphery, therefore
In two images corresponding to adjacent view environment, the record result to the image of overlapping region should be completely the same.That is, weight
Folded region A the first image 201 with should be identical in the second image 202, accordingly, other any overlapping regions are adjacent
Record result in two images is also completely the same.If overlapping region in two images corresponding to adjacent view environment
When recording inconsistent of image, must be that position, angle of a certain camera etc. are changed, the image for causing it to photograph
Visual angle environment changed, it may be necessary to panoramic parking system is re-scaled, when this changing value it is smaller (such as
Correspond to the range deviation that caused deviation in actual environment only has several centimetres), the influence brought for the process of parking can
Ignore, now without being re-scaled to panoramic parking system.Can be to the setting in this step according to actual conditions
Deviation threshold is selected, premised on ensureing the security during parking, according to the deviation of the image of overlapping region
Measurement criteria, selection setting deviation threshold, such as:Above-mentioned deviation be according to the line number or columns of pixel be measurement unit or
Using image deviations distance as measurement unit, corresponding setting deviation threshold is also different.But the deviation can be according to mark
The mapping relations or operation relation of timing determination, it is corresponding to obtain the offset distance in actual environment, the setting deviation threshold
The offset distance threshold value that can be corresponded in actual environment.Such as, it is necessary to again when actual environment large deviations distance is more than 10 centimetres
Demarcate panoramic parking system, then counter push away can obtain pair according to the measurement unit of the deviation of the image of selected overlapping region
The setting deviation threshold answered.
S103:Send the cue that need to be re-scaled.In this step, the cue can be by instrument board
Indicator lamp is prompted, can be with additional alarm prompt tone.Purpose is to remind driver, and now panoramic parking system needs weight
New demarcation, the panoramic view now obtained have relatively large deviation, influence may be brought on the process of parking.Driver can contact as early as possible
4S shops, producer etc. re-scale to panoramic parking system.
By such scheme, mainly analyze whether automatic decision is needed to panoramic parking system again according to image difference
Demarcation, has higher accuracy, when finding that satisfaction re-scales condition, reminds driver immediately, guarantee driver and
When get the cue for re-scaling parking system, avoid driver using having parking system devious to process of parking
Bring potential safety hazard.
