Embodiment 2 (production of 3D seal)
1, body local region 3D information collection
Referring to FIG. 3, acquisition equipment specifically includes: track 101, image capture device 201, processor 100, telecontrol equipment
102, image capture device 201 is mounted on telecontrol equipment 102, and telecontrol equipment 102 can be moved along track 101, so that
The pickup area of image capture device 201 constantly changes, and is formd on the scale of a period of time in the more of space different location
A pickup area constitutes acquisition matrix, but in only one pickup area of some moment, therefore acquisition matrix is " virtual "
's.Since image capture device is usually made of camera, also referred to as virtual camera matrix.But image capture device may be to take the photograph
Camera, CCD, CMOS, camera, the mobile phone with image collecting function, plate and other electronic equipments.
The matrix dot of above-mentioned virtual matrix is determined by the position of image collecting device when acquisition target person image, adjacent
Two positions at least meet following condition:
H* (1-cosb)=L*sin2b；
A=m*b；
0<m<1.5
Wherein L is the distance that image collecting device 201 arrives target person, and usually image collecting device 201 is at first
Apart from the distance in target person face collected region when setting.
H is target person actual size in acquired image, and image is usually image collecting device 201 in first position
When the picture that shoots, the target person in the picture has true geometric dimension (not being the size in picture), measures the ruler
Along the orientation measurement of first position to the second position when very little.Such as first position and the second position are the relationships moved horizontally,
So the size is measured along the horizontal cross of target person.Such as the target person left end that can show that in picture is A,
Right end is B, then measures the linear distance of A to B on target person, is H.Measurement method can be tied according to A, B distance in picture
It closes camera lens focal length and carries out actual distance calculation, A, B can also be identified on target person, it is straight using other measurement means
Connect measurement AB linear distance.
A is two neighboring location drawing picture acquisition device optical axis included angle.
M is coefficient.
Since article size, concave-convex situation are different, the value of a can not be limited with strict formula, needs rule of thumb to carry out
It limits.According to many experiments, the value of m preferably can be within 0.8 within 1.5.Specific experiment data are referring to such as
Lower table:
| Target person | M value | Synthetic effect | Synthetic ratio |
| Human body head part | 0.1、0.2、0.3、0.4 | It is very good | > 90% |
| Human body head part | 0.5、0.6 | It is good | > 85% |
| Human body head part | 0.7、0.8 | It is relatively good | > 80% |
| Human body head part | 0.9、1.0 | Generally | > 70% |
| Human body head part | 1.0、1.1、1.2 | Generally | > 60% |
| Human body head part | 1.2、1.3、1.4、1.5 | Synthesis reluctantly | > 50% |
| Human body head part | 1.6、1.7 | It is difficult to synthesize | < 40% |
After target person and image collecting device 201 determine, the value of a, root can be calculated according to above-mentioned empirical equation
It is that can determine the parameter of virtual matrix, i.e. positional relationship between matrix dot according to a value.
In general, virtual matrix is one-dimensional matrix, such as along the multiple matrix dots of horizontal direction arrangement (acquisition position
It sets).But when some target person objects are larger, two-dimensional matrix is needed, then two adjacent in vertical direction positions are equally full
The above-mentioned a value condition of foot.
Under some cases, even from above-mentioned empirical equation, also it is not easy to determine matrix parameter (a value) under some occasions, this
When need to adjust matrix parameter according to experiment, experimental method is as follows: prediction matrix parameter a is calculated according to above-mentioned formula, and according to
Matrix parameter control camera is moved to corresponding matrix dot, such as camera shoots picture P1 in position W1, after being moved to position W2
Picture P2 is shot, whether compare at this time has the part for indicating target person the same area, i.e. P1 ∩ P2 in picture P1 and picture P2
Non-empty (such as simultaneously including human eye angle part, but photograph taking angle is different), if readjusting a value without if, is moved again
It moves to position W2 ', repeats above-mentioned comparison step.If P1 ∩ P2 non-empty, continued to move to according to a value (adjustment or unadjusted)
Camera shoots picture P3, comparing whether to have in picture P1, picture P2 and picture P3 again indicates that target person is same to the position W3
The part in region, i.e. P1 ∩ P2 ∩ P3 non-empty.It recycles plurality of pictures to synthesize 3D, tests 3D synthetic effect, meet 3D information and adopt
Collection and measurement request.That is, the structure of matrix is determined by the position of image collecting device when acquisition multiple images
, adjacent three positions meet three images acquired on corresponding position and at least there is expression target person the same area
Part.
After virtual matrix obtains multiple target person images, the above-mentioned image of processor processing synthesizes 3D.Utilize camera
The multiple images synthesis 3D point cloud or image of multiple angles of shooting, which can be used, carries out image spelling according to adjacent image characteristic point
Other methods also can be used in the method connect.

It is appreciated that using other 3D acquisition modes such as structure light, laser scanning, coordinate measuring machines or can also obtain
Obtain 3D information.
The object of acquisition includes the 3D biological attribute data of legal representative, such as hand, refers to portion, face, iris 3D biology
At least one of characteristic information.In order to protect privacy, a part of 3D information of a certain organ can be only acquired, so that seeing
The person of examining, which can not directly visually observe to obtain acquisition target according to seal designs, can be identified the information of identity, i.e., can not be according to seal
Pattern naked eyes tell seal ownership people.Such as can acquire left index finger, right face cheekbone area, nose, upper lip, ear,
Palm, iris of both eyes.It is appreciated that acquisition target can be each 3D information of human body region more abundant, or this
The a part in a little regions, while can also be spliced with multiple regions.Palm palmmprint 3D information and right face 3D information can be used for example
It is stitched together, forms a complete 3D rendering.The seal designs that the seal or printing produced in this way come out intuitively more have
Fascination, more can not be by visually identifying that whom object is.Moreover, tradition is using people's two dimension portrait as the seal of seal content
When in use, once seal is imitated, due to the uniqueness of portrait, the portrait of the client is scrapped as the mode of seal, nothing
Method is that the user makes portrait seal again.And since human body surface has many regional areas comprising three-dimensional information (such as left
The region of half of nose, right hand index finger and splicing regions of left forehead etc.) can arbitrarily replace other partial 3 d information or
Other concatenation informations are as new seal.Since the regional area that human body surface includes three-dimensional information is more, and can mutually arrange
Column combination is spliced, therefore seal content can be replaced frequently, and seal is imitated the confidentiality for not influencing new seal.
It not only can still make seals that other include biology 3D feature for client after seal fails in this way, while can also be with
Seal is needed to frequently replace according to user, further increases safety.
