Background technology
The binocular that three-dimensional measurement is mainly formed using two video cameras or a video camera with optics mirror-lens system is stood
Body vision sensor, the multiple image of the same space object is obtained from diverse location or angle shot, is based on principle of parallax
The three-dimensional geometric information of object can be obtained, rebuilds 3D shape and the position of surrounding scene.Three-dimensional measurement generally has following several
Method:
Firstth, structure light vision e measurement technology.Mainly by projecting the structure light of corresponding modes to measurand, by imaging
Machine shooting deformation optical strip image, the three-dimensional information of body surface is obtained based on optical triangulation theory.The technology turns into be solved
One of effective ways of many on-line measurements such as object surface appearance measurement, spatial position measuring, three-dimensional motion information acquisition, tool
There is the features such as non-contact, dynamic response is fast, system flexibility is good, be widely used in Product rapid design and processing quality control, inverse
To engineering and the numerous areas such as automatically control.
Secondth, phase shift measurement technique (PMP).It is to calculate each picture using several grating fringe images of certain phase difference
The phase value of element, the elevation information of object is then calculated according to phase value.Detailed process is as follows:Thrown first to testee surface
Grating fringe is penetrated, the striped projected is deformed by the shape modulation of body surface, then the stripe pattern of deformation is entered
Row processing, demodulates the phase information for representing object height, finally calculated by Carrier-smoothed code and geometry be obtained with by
Survey the three-dimensional geometric information of body surface.PMP methods need the grating fringe image at least more than three width to carry out phasometer
Calculate, while testee is immovable in shooting process, is generally suitable for the three-dimensional measurement of stationary body.
3rd, cofocus scanning technology.Based on the principle of an illumination, point imaging and point 3 points of conjugation of detection, work as measured surface
When being conjugated with test surface, the light energy that the picture point on point probe is minimum, and point probe receives is maximum;When measured surface is inclined
During from object point, the picture point on detector becomes big, and the light energy that point probe receives diminishes.Object point and tested surface are controlled during measurement
Overlap, ensure that the output valve of detector is maximum, the pattern of measured surface can be depicted.Confocal measurement method (such as confocal laser
Flying-spot microscope) due to its high accuracy, high-resolution and be easily achieved the digitized unique advantage of three-dimensional imaging it is biomedical,
It is used widely in the fields such as semiconductor detection.
4th, digital speckle technology, speckle image is recorded with digital method, by speckle image progress before and after deformation
Match somebody with somebody, to obtain the deformation data of object under test, that is, digital speckle correlation measurement method.Here " image " represents all anti-
Answer the visual carrier of object plane information, including the other forms of laser speckle image, artificial speckle image and reactant region feature
Image.Due to digital speckle correlation measurement technology have it is fairly simple to the acquisition mode of initial data, measuring environment is wanted
Ask it is low, can direct measurement displacement and strain two group informations, be easy to implement the advantages that Automatic survey, material stress strain survey
It is used widely in the fields such as amount, structure endurance analysis.
In addition, also disclosing that a kind of hand-held scanner device in CA2686904A1, can be completed under two kinds of operator schemes
3-D scanning.
But above-mentioned method for three-dimensional measurement is typically only capable to obtain the three-dimensional geometric information of object under test, and can not provide complete
Colour information.In order to obtain colour information, also occur certain methods in the prior art, it is specific as follows:
CN104251995A is disclosed in the introduction to carry out two dimension to scene using color camera and takes pictures, then by colour
Photo is synthesized with three dimensional point cloud, obtains color three dimension cloud data indirectly, generates colorful three-dimensional model.
CN104776815A is further disclosed during measuring three-dimensional profile in the introduction, while measures object
Two kinds of solution methods of colouring information:When projection infrared structure light, in the color data phase for obtaining object color information
IR-cut filter plate is added before machine;Second, by way of stroboscopic structure light, first projecting structural optical, while shoot structure
The image of light is used to calculate three-D profile, turns off the colouring information that structure light shoot coloured image is used to calculate object.
Further provided in CN102980526A only with black and white camera obtain coloured image spatial digitizer and its
Scan method.Its disclosed spatial digitizer, including a projecting apparatus, at least one black and white camera and a control system.Institute
State projecting apparatus and project three kinds of monochromatic light of red, green, blue to scanned object respectively.When the projecting apparatus projects often to scanned object
During kind monochromatic light, at least one black and white camera shoots multiple images of scanned object from multiple angles respectively.The control
System processed can throw the gray value for the image that red light collects as the value of red channel using projecting apparatus, throw green light and collect
Image value of the gray value as green channel, the gray value of the image collected using throwing blue light is used as blue channel
Value, is worth to complete coloured image, so as to obtain the coloured image of the multiple angles of scanned object by the triple channel combined.
CN202074952U technical principle is similar with CN102980526A, wherein further highlighting using only single-phase
The three-dimensional appearance and color texture of machine-single projector obtain system.
A kind of Aristogrid is disclosed in CN1426527A, including two cameras and two projectors, projector
In an optical grating element for being used to project coding pattern on target object surface, another is used to obtain the line of target object
Manage information.
The present invention is namely based on digital speckle technology and realizes that three-dimensional data obtains, and still, the data so obtained can not carry
For full color information, therefore, when needing colored structures, pass through the image that texture information camera gathers and three-dimensional data phase
Match somebody with somebody, you can obtain the three-dimensional object structure of colour.
