Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
Embodiment one：
Fig. 1 shows the realization flow of the detection method of panorama camera splicing effect provided in this embodiment, for the ease of
Illustrate, illustrate only part related to the present embodiment, details are as follows：
In a step 101, set multiple range points, the distance of multiple range points and panorama camera in nearest image-forming range and
Between the farest imaging range.Wherein, range points are more remote apart from panorama camera, and distance is bigger.Nearest image-forming range just refers to image
Head can be with respect to the minimum distance of blur-free imaging.The farest imaging range just refers to that camera can be with respect to the most long distance of blur-free imaging
From.
In a step 102, stitching image of the article in each piece position of each range points is obtained.
It, can be with the more complicated object of a surface texture in the every of each piece position of panorama camera in specific implementation
At a range points, processing of taking pictures all is carried out, obtains the stitching image of multiple objects.
In step 103, original image of the article in the non-piece position of each range points is obtained.
In specific implementation, can be continuing with object in step 102 the non-piece position of panorama camera it is each away from
From at, all carry out processing of taking pictures, obtain the original image of multiple objects.
At step 104, each splicing is obtained according to each stitching image and the corresponding original image of each stitching image
The distortion value of image.
In specific implementation, step 104 can include following two sub-steps：
A. the corresponding original image of each stitching image and each stitching image is subjected to registration to obtain
Take overlapping region.
B. the distortion value of each stitching image in the overlapping region is obtained.Wherein, obtain in the overlapping region
Each the distortion value of stitching image can be specially：Obtain each pixel of each stitching image in the overlapping region
The square value of the difference of the pixel of the original image corresponding with each pixel of each stitching image；To in the coincidence
The corresponding square value of each pixel of each stitching image is averaged in region；Distortion value is set as average value.
In step 105, splicing effect value is obtained according to all distortion values.
Wherein, step 105 can be specially：Splicing effect value is obtained according to all distortion values, splicing effect value is institute
The standard variance of some distortion values.
Further, as shown in Fig. 2, further including step 102-1 between step 101 and step 102.
In step 102-1, multiple piece positions are obtained according to the nominal parameters of panorama camera.
For example, can first by panorama camera be fixed on one it is spacious, light is consistent, in the environment of solid colour, if
Fixed 4 range points Dj, the distance of 4 range points and panorama camera between nearest image-forming range and the farest imaging range, according to
The nominal parameters of panorama camera obtain 6 piece position Pi, with the more complicated object of a surface texture panorama camera kth
A edge joint position, according to DjDistance, carry out processing of taking pictures, obtain stitching image Ik,j, the object is continuing with, in panorama camera
Non- edge joint position, according to DjDistance, carry out processing of taking pictures, obtain original image Sj, using image registration techniques, by spliced map
As Ik,jWith original image SjRegistration is carried out, the overlapping region R of the two is obtained, obtains each spliced map in the overlapping region R
As Ik,jEach pixel and each stitching image Ik,jThe corresponding original image S of each pixeljPixel difference square value
dk,j,m, m ∈ R；To each stitching image I in the R of overlapping regionk,jThe corresponding square value d of each pixelk,j,mIt averages
Dk,j；Distortion value is set as average value Dk,j, according to all distortion value Dk,jSplicing effect value is obtained, splicing effect value can be with
For all distortion value Dk,jStandard variance, splicing effect value it is smaller, represent dynamic splicing effect it is more stable, splicing effect value
It is bigger to represent more unstable.
The present embodiment by setting multiple range points first, the distance of multiple range points and panorama camera nearest imaging away from
From between the farest imaging range；Obtain stitching image of the article in each piece position of each range points；Article is obtained to exist
The original image of the non-piece position of each range points；According to each stitching image and the corresponding original image of each stitching image
Obtain the distortion value of each stitching image；Splicing effect value is obtained according to all distortion values；It is thereby achieved that objectively to examine
Survey method characterizes the dynamic splicing effect of panorama camera.
