Integrated, the face shape information of optical surface can be obtained, in the ideal case, trapezoidal integration is carried out to corrugated,
Z=∫ (gxdx+gydy) (5)
The 3D faces shape of glass surface can be recovered with iteration repeatedly by integrating.
The measuring method is according to photocentre of the normal of minute surface sample point (or perhaps x, y to slope) with aperture camera
Functional relation between coordinate, the screen pixels point coordinates for lighting measured lens surface sample point and minute surface sample point coordinate, is again assumed that
Precognition face shape provides a preferable initial value, finally tries to achieve the slope and face shape of tested minute surface according to functional relation iteration,
Functional relation between them is represented with equation below (6)：
Wherein, xmAnd ymIt is the coordinate on surface to be measured, can be obtained from the dimensional measurement of measurement apparatus；xcameraAnd ycamera
It is the coordinate of CCD camera 15, can be obtained from the dimensional measurement of measurement apparatus；xscreenAnd yscreenIt is LCD display screen bright spot

In formula (6), due to slope wx(xm,ym)、wy(xm,ym) it is surface face shape w (xm,ym) function, therefore counting
Need to provide a preferable initial value when calculating slope, can generally use a preferable surface face shape or other measurement sides
Method obtains face shape to provide a preferable primary face shape valuation, is designated as w0(xm,ym), by w0(xm,ym) replace in formula (6)
w(xm,ym) (x can be obtainedm,ym) place x, y is to slope data, then the face shape w that will be calculated by slope1(xm,ym) replace
W (x in formula (6)m,ym), and then another group of slope is obtained, by that analogy, pass through slope calculations and the face shape of iterating.On
It is the method restored using one camera to state formula, but this measurement apparatus is using the measuring method of left and right double camera, two
One camera iterates to calculate slope and face shape by the above method respectively, the technology then merged by picture, successive ignition until
Export entire surface shape.The scheme advantage that this list-double camera is combined is that visual field can be increased, that is, adds measurement range, and
And more complicated face shape can be measured.
For the measurement of 3 d shape, the measuring method restored using one camera, it is necessary first to a precognition face shape is determined,
If precognition face shape and tested surface shape difference are larger, program convergence can be caused slowly, precision and the speed of service can be a greater impact,
Calibration process is higher to geometric calibration required precision simultaneously, and the measurement accuracy of the reference planes of selection can directly affect final
Measurement result.
The measuring method restored using double camera, measurement visual field is small, and its effective coverage measured is the public affairs of two viewing field of camera
Intersecting area altogether, and because it is directly scanned to entire surface shape, data volume is big, and program operation speed is slow, it is impossible to multiple
Beans flour noodle shape measures recovery.Double camera solid deviation art is simply introduced below, as shown in figure 12.
Double camera measuring principle：Measured respectively using double camera, each pixel of camera is obtained after measurement and corresponds to incident ray
The particular location of direction and observation station on screen.However, for single camera, cause because height is uncertain true
The normal vector of reflecting surface can not determine, but can calculate normal vector corresponding to different height, the measuring method of two cameras
It is also based on this principle.Only in the plane of true altitude, the two normal vectors could overlap, by measuring different pixels point
Corresponding incident ray direction, it can obtain the normal vector distribution in plane, you can obtain body surface slope distribution.
The problem of existing for such scheme, this programme propose the list based on binocular vision and digital image correlation-bis-
The method that camera is combined.The elevation information of 20 points of intersecting area is gathered first with double camera, is then fitted to one
Primary face shape, as the reference plane of tested surface shape, then the primary face shape input as one camera, it is straight to enter line slope iterative calculation
To the 3 d shape information of output measured piece, such program operation speed greatly improves.
The advantage for the method being combined using list-double camera：1st, it is big to measure visual field；2nd, arithmetic speed greatly improves；3rd, it is right
The calibration request of hardware substantially reduces；4th, the face shape of complexity can be measured.
Operation principle of the present utility model is as follows：
1) area source use, and projective structure light are served as using 32 cun of high brightness LCD screen display；
2) structure light of area source projection, is radiated on 3D bend glasses, 3D bend glasses are placed on can at an angle
On the two-dimentional self-powered platform of lifting, after area source is irradiated to testee, in two CCD phases after testee surface is reflected
It is imaged on machine, by adjusting workbench height, further adjusts the position of 3D glass and the position of CCD camera, left and right camera
Install at an angle respectively, by adjusting the position of CCD camera and workbench, make structure light as much as possible in tested 3D
Show on glass, and obtained by CCD camera；
3) modulation image that structure light is formed after object under test surface is reflected, then passes through digital image correlation, phase
Unwrapping algorithm, the phase diagram of modulation image is obtained, and the pixel coordinate for the pixel coordinate and camera for finding out screen corresponds
Relation；The parameter of combining camera demarcation, by the distribution that the distribution shifts of phase are position coordinates, and by phase calibration information with it is empty
Between positional information it is corresponding；Light three-dimensional deviation art technology is finally utilized, establishes phase change amount and the face shape gradient of object under test
Information.
4) restored method being combined using list-double camera, can by known gradient information along slope direction iterated integral
To carry out Surface reconstruction, so as to recover to the face shape of 3D glass.
Specific embodiment of the utility model is these are only, but the technical characteristics of the utility model is not limited thereto.Appoint
How based on the utility model, to realize essentially identical technique effect, made ground simple change, equivalent substitution or repair
Decorations etc., are all covered by among the scope of protection of the utility model.
