Abstract
The invention belongs to the non-contact optical scanning technique field and relates to a color three-dimensional optical scanning method capable of processing transparent and highlight materials. The color three-dimensional optical scanning method is characterized by comprising the following steps that: (1) reusable mark points are bonded on an object which is intensive in surface mirror reflection or has high transparency; (2) under the positioning of the reusable mark points, the three-dimensional scanning and automatic splicing of the object are completed; (3) a contrast aid is sprayed on portions of the object, the point cloud of the portions of the object cannot be acquired, the contrast aid covering the reusable mark points is wiped out; (4) the object is scanned again, point cloud is extracted directly, and splicing is performed by using the reusable mark points, and complete scanning is performed; and (5) any conventional processing flows such as grid surface encapsulation, grid surface hole filling, smoothing and simplification are completed, a model is repaired to be complete as far as possible. The color three-dimensional optical scanning method of the invention can process the color data collection of the transparent and highlight materials with convenience and quickness. The application of the color three-dimensional optical scanning method can be expanded.
Description
Technical field
The present invention relates to Non-contacting optical scanning technical field, more particularly to a kind of process transparent and bloom material
Color three dimension optical scanning method.
Background technology
Three-dimensional optical scanning technique is a kind of for detecting and to analyze the shape of object or environment in real world（Geometry structure
Make）With the technology of appearance data；The data collected often are used for three-dimensional reconstruction calculating, create actual in virtual world
The mathematical model of object.These models have quite extensive purposes, such as industrial design, Defect Detection, reverse-engineering, robot
Guiding etc..With industry 4.0,3D printing and the rise of VR, the requirement more and more higher to 3-D scanning technology, but traditional industry
Spatial digitizer, can only catch the point cloud with spatial positional information, it is impossible to automatically form the color model of material object；In recent years,
On the basis of traditional industry scanning, some color three dimension scanning techniques are also developed, but these technologies are all identical in the presence of some
Shortcoming, cannot exactly process transparent and bloom material chromoscan problem, such as automobile metal plate work, working of plastics thoroughly high, from
And very big inconvenience is brought to practical application, limit the application field of the technology.
The content of the invention
It is an object of the invention to solve the problems, such as that prior art cannot process transparent and bloom material chromoscan, there is provided
It is a kind of to process transparent and bloom material color three dimension optical scanning method, so as to expand the application neck of three-dimensional data significantly
Domain.
To achieve these goals, the present invention provides following technical scheme：
It is a kind of to process transparent and bloom material color three dimension optical scanning method, comprise the following steps：
（1）Reusable index point is pasted for the object that surface specular reflections are strong or the transparency is stronger；
（2）Under the positioning of the reusable index point, the 3-D scanning and automatic Mosaic of object are completed, now, as long as by
The reusable index point, the position splicing of object all angles is complete, and for each position, collect with
The colour picture of elements of exterior orientation；
（3）The position of a cloud can not be collected using contrast enhancement agents painting objects, then erasing is covered in the reusable mark
The contrast enhancement agents above will point；
（4）Object is scanned again, and point cloud is extracted in this time scanning without gathering colour picture, directly, and utilizes the reusable mark
Will point splices, and scanning is complete；
（5）Then complete grid surface encapsulation and grid surface filling-up hole, smooth, simplify etc. any conventional handling process, as far as possible
Model is repaired complete；
（6）Positioned by automatically texture and mapped system is calculated and optimized, three-dimensional of the output with texture mapping information is color
Color model.The automatically texture is positioned and the principle of mapped system is to have used the reusable index point in twice sweep process
The constant characteristic of middle relative position, and by the internal and external orientation of colour picture, the grid for input carries out shadowing
And picture mapping, finally export color model.
Above-mentioned steps（2）In, when scanning is less than cloud, it is also possible to complete above-mentioned steps（6）In the texture mapping.
Beneficial effects of the present invention are：If traditional scan method is not by contrast enhancement agents, it is impossible to collect coordinate
Point, also cannot just extract the shape of object, even with contrast enhancement agents, because the covering of powder, cannot also extract the color of object
It is color；And the present invention is thoroughly solved for transparent using reusable index point and with the cooperation of automatically texture positioning and mapped system
With the automatic three-dimensional colour modeling problem of bloom material so that for virtual reality, museum's color data gather etc. industry provide
Convenience, has expanded the application field of the technology significantly.

The reusable index point, the position splicing of object all angles is complete, and for each position, collect with
The colour picture of elements of exterior orientation；
（3）The position of a cloud can not be collected using contrast enhancement agents painting objects, then erasing is covered in the reusable mark
The contrast enhancement agents above will point；
（4）Object is scanned again, and point cloud is extracted in this time scanning without gathering colour picture, directly, and utilizes the reusable mark
Will point splices, and scanning is complete；
（5）Then complete grid surface encapsulation and grid surface filling-up hole, smooth, simplify etc. any conventional handling process, as far as possible
Model is repaired complete；
（6）Positioned by automatically texture and mapped system is calculated and optimized, three-dimensional of the output with texture mapping information is color
Color model.The automatically texture is positioned and the principle of mapped system is to have used the reusable index point in twice sweep process
