Example, it should all belong to the scope of the utility model protection.
It refer to Fig. 1, a kind of dress for being used to eliminate the overlapping deviation of 360 degree of shooting images that the utility model embodiment provides
Put, including annular wall 10, there are calibration maps 11 in the inner surface setting of the annular wall 10, the calibration maps 11 have and the ring
The parallel first edge 110 of the circumference of shape wall 10, and the surface of the calibration maps 11 is non-reflective.
Wherein, the circumference of annular wall 10 refers to and the plane of the central axis of the annular wall 10 and the annular wall 10
The intersecting lens of inner surface.
The present embodiment device is applied to the camera module of 360 degree of panoramic pictures of shooting, is taken the photograph for eliminating camera module first
As existing overlapping deviation after head shooting image and the splicing of second camera shooting image, calculating can be aided in take the photograph using the device
As module the first camera shooting image and second camera shooting image between existing overlapping region.
The overlapping region between two camera shooting images of camera module is calculated using the present apparatus, is specifically included following
Step：
S20：Camera module is fixed at the center in device annular wall, and the first of the camera module and calibration maps
Edge is in same plane, and the camera module includes two pieces opposite to each other to the camera of assembling, wherein, the first camera is backwards to institute
Calibration maps are stated, second camera is used to eliminate 360 degree of shooting image weights towards the calibration maps, described device to be above-described
The device of folded deviation.
In this method, the camera module for shooting 360 degree of panoramic pictures is included opposite to each other to the He of the first camera 1 of assembling
Second camera 2 (can also be referred to as preceding camera and rear camera).
In this step, Fig. 2 is referred to, camera module is fixed at the center of device annular wall 10, and camera module
Same plane is in the first edge of calibration maps 11, i.e. camera module is located at the central axis of annular wall 10 and is mark
Determine in the plane where Figure 11 first edges.
First camera 1 is backwards to calibration maps, and second camera 2 is towards calibration maps, in the horizontal positioned state of annular wall 10
Under, upward, second camera 2 is downward for specially the first camera 1.
S21：The camera module shoots picture.
After upper step fixes camera module, shot simultaneously using two cameras of camera module, it is corresponding to obtain
Two width pictures.
S22：In the picture that first camera shooting obtains, by circumference where the first edges of the calibration maps with
Region between picture edge is defined as the inactive area of the first camera shooting picture, is shot in the second camera
In the picture of acquisition, the region where the first edge of the calibration maps between circumference and picture edge is defined as described second
Camera shoots the inactive area of picture.
The angle of visual field of first camera 1 and second camera 2 is all higher than 180 degree, in the picture that two cameras photograph
In calibration maps 11 can all occur.In this method, the first edges 110 of calibration maps 11 is make use of to demarcate the first camera shooting figure
The overlapping region of picture and second camera shooting image.
Fig. 3 is refer to, if by two width pictures so that circumference is splicing line where demarcation Figure 11 first edge in picture, by two
Auxiliary picture splices, and in the image obtained after splicing, the region between the edge line of two width graphic images is two width pictures
Overlapping region.The picture center of first camera 1 shooting picture is O1, picture center O1Distance to picture edge is R1, picture
Center O1The distance of circumference is a where to the first edge of calibration maps 11；The picture center that second camera 2 shoots picture is O2, draw
Face center O2Distance to picture edge is R2, picture center O2The distance of circumference is b where to the first edge of calibration maps 11.
In this method, in the first camera 1 shoots picture, by circumference where the first edge of calibration maps 11 and picture edge
Between region be defined as the first camera shooting picture inactive area；, will in the picture that the shooting of second camera 2 obtains
Region where the first edge of calibration maps 11 between circumference and picture edge is defined as the dead space that second camera 2 shoots picture
Domain.
When handling computing, in the first camera 1 shoots picture, according to picture center O1To the distance R at picture edge1
And picture center O1The distance a of circumference, is calculated in the shooting image of the first camera 1 where to the first edge of calibration maps 11
Inactive area width be R1- a, will be with inactive area width R1- a is used as inactive area data, can be determined according to this data
The inactive area gone out in the shooting image of the first camera 1.In second camera 2 shoots picture, according to picture center O2To picture
The distance R at face edge2And picture center O2The distance b of circumference, is calculated the second shooting where to the first edge of calibration maps 11
Inactive area width in first 2 shooting image is R2- b, by inactive area width R2- b is used as inactive area data, according to this
Data can mark off inactive area in the shooting image of second camera 1.
The inactive area data of the first obtained camera and second camera recorded to the data processing of camera module
In module, in actual photographed, data processing module is according to the inactive area data of record, the figure that the first camera is photographed
The inactive area of picture is cropped, and the inactive area for the image that second camera is photographed crops, and the image after cutting is spelled
Connect, you can 360 degree of complete or collected works' images of the overlapping deviation that has been eliminated.
As can be seen that being used for the device for eliminating the overlapping deviation of 360 degree of shooting images using the present embodiment, calibration maps are utilized
First edge demarcates the first camera shooting image of camera module and the overlapping region of second camera shooting image, obtains
To the inactive area of the first camera shooting image and the inactive area of second camera shooting image of camera module, to pass through
First camera shooting image and second camera shooting image are cut, realizes and eliminates for 360 degree of panoramic pictures of shooting
Overlapping deviation existing for image captured by camera module.This method is simple, accurate compared with prior art, takes short.
The present embodiment is used for the device for eliminating the overlapping deviation of 360 degree of shooting images, and the surface of the calibration maps is non-reflective, makes
Camera module shooting image in calibration maps scene comparison with around it is obvious, can be transparent to show that out, make calibration maps side
Edge is transparent to show that out, convenient to calculate.Exemplary, the surface of calibration maps can be black.
In the present embodiment, the shape of calibration maps 11 is not limited, as long as meeting that calibration maps 11 have the circle with annular wall
