The concentricity at the center of the heart and inner glass；Concentricity measurement is carried out for dual camera optical filter, measured images to be double
The center of the external structure in head glass of color filter region and the concentricity at the center of the internal structure of glassy zone.
With being readily apparent that, the number of optical filter can be one, two in the initial pictures comprising optical filter got
Or it is multiple, it is not limited thereto.Latter embodiments are to carry out concentricity measurement to single optical filter in image to illustrate
Illustrate, when including two or more optical filters in piece image, enter with reference to the method to the measurement of single optical filter concentricity
Row measurement, is repeated no more.
In S102, target area image is extracted from the initial pictures, using the target area image as to be measured
Image；The target area image is image corresponding with optical filter exterior contour in the initial pictures.
In the present embodiment, the background parts that may include in the initial pictures comprising optical filter got are more, and
The ratio of entire image shared by optical filter is smaller, now if directly carrying out image procossing, can make nothing in the image information of processing
The background information of effect is too many, influences the speed of image procossing and the precision of concentricity measurement.Therefore, can be first from getting
Target area image corresponding to optical filter exterior contour is extracted in initial pictures comprising optical filter, target area image is made
For testing image.Follow-up image procossing is carried out only for testing image, so as to improve the speed of image procossing and concentricity
Measurement accuracy.
, can be by being positioned to the position of optical filter in the picture, to extract as one embodiment of the present of invention
Target area image.As shown in figure 4, S102 may comprise steps of：
In S401, the exterior contour of optical filter is determined in the initial pictures；The exterior contour is optical filter
The profile of outermost.
In the present embodiment, can be by carrying out binary conversion treatment to the initial pictures got, to obtain optical filter
Exterior contour.Wherein, exterior contour refers to the profile of the overall outermost distinguished with background of optical filter, that is, institute in image
Enclose the maximum profile of region area.Preferably, binary conversion treatment is carried out to initial pictures using big law.
In S402, optical filter is positioned according to the exterior contour, obtains the positional information of optical filter.
In the present embodiment, the position of the minimum enclosed rectangle of exterior contour is the position of optical filter.According to outer wheels
Wide positional information can obtain the positional information of optical filter.
In S403, the target area image is extracted according to the positional information, using the target area image as
The testing image.
In the present embodiment, due to follow-up need that testing image is carried out the processing such as to rotate, therefore target area is appropriate
More than the position of optical filter.The background area of preset range can be expanded laterally on the position of optical filter, according to being expanded
Background area position extraction testing image.
Preferably due to the non-can completely of optical filter is likely to occur in the initial pictures of the optical filter photographed collects figure
As upper situation (such as situations such as skew of optical filter putting position or position skew of image collecting device), in extraction target area
Before area image, it can be judged according to the exterior contour of optical filter.If the minimum enclosed rectangle of exterior contour is entirely located in just
In beginning image, then the initial pictures are qualified image, carry out follow-up target area image extraction；If the minimum of exterior contour
Boundary rectangle is not entirely located in initial pictures, then the initial pictures are underproof image, and the initial pictures are deleted
Remove, without subsequent treatment.
Preferably, for ease of subsequent treatment, rotational correction can be carried out to the optical filter in the testing image that extracts.Rotation
Turn correction the step of be：The testing image of acquisition is first replicated into portion, Da-Jin algorithm binaryzation is carried out to the testing image of duplication, with
Inversion operation is carried out to testing image afterwards；Each profile in testing image is extracted, excludes the profile beyond largest contours；To most
Big contours extract minimum enclosed rectangle, the center of an angle and rectangle can be obtained, if angle be less than preset range when
Wait such as -45 degree, then correction angle is exactly that the angle adds 90 degree；According to the angle and rectangular centre got with affine change
Change and testing image is rotated, the image of rotation is the image after binaryzation, is negated again to obtaining image, returns to the figure
Picture, rotational correction just complete.
In S103, denoising is carried out to the testing image.
In the present embodiment, due to oneself factor of environmental factor or image collecting device etc., the filter got in S101
The image of mating plate may include flaw point, such as stain noise, or the filter regions of black occurs in the region of white background
There is white point noise etc., cause the testing image that subsequent extracted arrives equally to include noise.Therefore testing image can be gone
Make an uproar processing, avoid because of the measurement accuracy of influence of noise optical filter concentricity.
As one embodiment of the present of invention, can by by testing image with by binary conversion treatment and negating processing
Image template is contrasted, and denoising is carried out to the testing image according to comparing result.As shown in figure 5, S103 can include with
Lower step：
In S501, binarization operation and inversion operation are carried out to the testing image.
In the present embodiment, binarization operation refers to image all pixels using a kind of come table in two pixel values
Show.Such as the gray value of the pixel on image is arranged to 0 or 255, that is, whole image is showed significantly only
Black and white visual effect.Inversion operation is that the gray value of pixel is changed into 255 from 0, or is changed into 0 from 255, from visual effect
On see it is that the black region on image and white portion are exchanged into color.
In S502, each profile in the testing image after binarization operation and inversion operation is extracted；Each wheel
Exterior feature is respectively enclosed to certain region area.
In the present embodiment, profile surrounds the area that certain region area refers to be surrounded by the closed curve for forming profile
The area in domain.After testing image carries out binaryzation and inversion operation, white point noise or stain noise may be included in image.Its
In, profile area defined area is often smaller corresponding to noise, and profile area defined area corresponding to optical filter
It is generally larger, therefore noise and optical filter can be distinguished by comparative silhouette area defined area.To each profile point
For the area not surrounded by being ranked up from big to small, the larger region contour of area is that profile, area corresponding to optical filter are smaller
Region contour be profile corresponding to noise.
In S503, using the descending preceding predetermined number profile of region area in each profile as template.
In the present embodiment, the descending preceding predetermined number profile of region area refers to area defined face in profile
The profile of the larger predetermined number of product.Then it is the profile maximum by region area is enclosed in each profile such as predetermined number is 2
The maximum profile with enclosed region area time, the image comprising the two profiles is as template.
As the implementation example of the present invention, each profile can be ranked up according to area defined area,
The less profile area defined area of sequence number is larger.Using less than or equal to the profile of default profile number as template.If for example,
Profile sequence number is followed successively by 1,2,3 ... ..., n, then No. 1 profile area defined area is maximum., will if default profile number is 2
Serial number 3,4 ... ..., n profile are removed, and only retain the profile of serial number 1 and serial number 2 as template.Therefore, pass through
Profile corresponding to noise is removed by this mode, profile only corresponding to reservation optical filter, will include the profile of preceding predetermined number
Generate the template for denoising contrast.
In S504, the testing image and the template are contrasted, the testing image is handled according to comparing result.
In the present embodiment, by the template obtained by S503 only to include the image of optical filter correspondence profile, and image passes through
Inversion operation is crossed, so the black region and white portion of template and testing image exchange.By contrasting testing image and template,
The profile being not present in testing image in template is removed, it is possible to achieve the denoising to testing image.By profile
The point pixel value of profile inner region can be arranged to consistent with the value of pixel neighbouring outside profile by removal.Specifically, respectively
The pixel value of corresponding pixel points in testing image and template is contrasted, if the pixel value of pixel is inconsistent in two images, is treated
The pixel value of the pixel is kept constant in altimetric image；If the pixel value of pixel is consistent in two images, in testing image
The pixel value of the pixel is negated (such as white point is changed into stain).
By carrying out denoising to testing image, the noise pixel point in testing image can be reduced, so as to improve filter
The measurement accuracy of mating plate concentricity.
In S104, the center of the first profile and the second profile in the testing image Jing Guo the denoising is calculated respectively
Point position；The first profile and second profile correspond respectively to the exterior contour and in-profile of optical filter.
In the present embodiment, the structure of optical filter includes exterior contour and in-profile.The first profile in testing image
Corresponding to the exterior contour of optical filter, the second profile corresponds to the in-profile of optical filter in testing image.Due to testing image
The middle profile that may include noise etc., therefore in the central point for only calculated during concentricity measurement the first profile and the second profile
Position.Concentricity can be represented by the distance between central point of the central point of optical filter exterior contour and in-profile,
Therefore it can realize that optical filter is concentric by the way that the center position of the first profile and the center position of the second profile is calculated
The measurement of degree.
As one embodiment of the present of invention, the four edges line of rectangle corresponding to the first profile and the second profile can be searched
Position, and the center position of rectangle is determined by four positions of rectangle, as shown in fig. 6, S104 may comprise steps of：
In S601, rectangle corresponding to the first profile described in the testing image and second profile is searched respectively
Four edges line position.
In S602, according to corresponding to the four edges line position calculates the first profile and second profile respectively
Four vertex positions of rectangle.
In S603, according to corresponding to four vertex positions calculate the first profile and second profile respectively
The center position of rectangle.
In the present embodiment, the structure of single camera optical filter and dual camera optical filter corresponds respectively to inside and outside two squares
Shape, therefore in testing image, the first profile and the second profile correspond to a rectangle respectively, can be by searching four of rectangle
The position in sideline determines the position of rectangle.Go out four vertex positions of rectangle by four edges line computation afterwards, by rectangle pair
Two summits at angle are connected into pairs linea angulata, and two cornerwise position of intersecting point of rectangle are the center position of rectangle, therefore
The center position of the first profile and the second profile can be obtained respectively.
Wherein, rectangle corresponding to the first profile can be the minimum enclosed rectangle or the first profile of the first profile
Maximum be inscribed rectangle；Rectangle corresponding to second profile can be the minimum enclosed rectangle or the second wheel of the second profile
Rectangle is inscribed in wide maximum；Specific set can be selected according to actual conditions, be not limited thereto.
The center position that the first profile can first be calculated calculates the center position of the second profile again, can also first calculate
The center position of second profile calculates the center position of the first profile again, or calculates the position of two central points respectively simultaneously
Put, be not limited thereto.
