Abstract
The invention discloses a space three-dimensional image acquisition system and belongs to the technical field of digital seeing and hearing. The space three-dimensional image acquisition system is characterized in that a reflecting curtain wall is arranged on the outermost layer of the system, light of a photography light is reflected onto a soft light cover by the reflecting curtain wall, the light is softened through the soft light cover, and thus the light on the surface of an object to be measured is made even and stable. After a data processing terminal controls all camera array units through a camera array wireless control unit to finish shooting synchronously, obtained ordinary two-dimensional pictures are uploaded to the data processing terminal through the camera array wireless control unit wirelessly, and a three-dimensional image is obtained after calculation and processing. The space three-dimensional image acquisition system has the advantages that two-dimensional image information of the object to be measured is acquired rapidly and effectively and is transmitted to the data processing terminal wirelessly, the three-dimensional image of the object to be measured is synthesized by the two-dimensional image information, and the texture of the obtained three-dimensional image is real, fine and smooth.
Description
Technical field
The invention belongs to digitizing audio visual technology field, relate to a kind of acquisition system of space three-dimensional image, specially refer to a kind of system that gathers object dimensional stereo-picture based on many ordinary digital cameras by array image pickup method.
Background technology
In recent years, along with three-dimensional cartoon, the rise of the industrial markets such as industrial design, increasing to the demand of high-quality three-dimensional images.In the market, dimensional Modeling Technology mainly contains two kinds: the one, and artificial modeling, mainly to adopt professional microcomputer modelling software drawing three-dimensional image on computers, this technical requirement modeling personnel possess very high painting ability and software operation level, there is modeling length consuming time, the shortcoming such as the validity of the image of drafting is low; Another kind is that the object by adopting professional 3-D view scanning device to set up image to need scans, and then obtains the measurements of the chest, waist and hips image of object.At present, such 3-D scanning equipment generally adopts the technology of laser scanning or structured light scanning to obtain the image of object, and the application technology of the method is comparatively ripe.But carrying out after object scanning owing to adopting this technology, what first it obtained is cloud data, and before obtaining complete three dimensional image, professional need to pass through loaded down with trivial details post-processed, and the image obtaining by the method exists texture fine and smooth not, has the shortcomings such as distortion.Therefore,, because the limitation of above method has limited the fast development of 3-D view industry, cannot meet fast, truly represent the demand of object dimensional effect.In the face of such market and technological fix, need a kind of high 3 D image acquring system of validity after simple to operate, three-dimensional reconstruction that has badly.
Summary of the invention
The object of this invention is to provide a kind of acquisition system of space three-dimensional image, this 3 D image acquring system not only has feature simple in structure, gathers fast and effectively object under test image information and this information exchange is crossed to the 3-D view that radios to data processing terminal synthetic object under test but also can realize.
By reference to the accompanying drawings, illustrate that a kind of 3 D image acquring system based on camera of the present invention is achieved by the following technical solution:
System of the present invention is mainly by reflective curtain enclosure wall 1, photography luminaire 2, soft light cover 3, camera array unit 4,8 six part compositions of camera array wireless energy control units 6 and photography luminaire wireless energy control units.The present invention, by special lighting mode, makes to produce one in b district, photographed region and stablizes soft photoenvironment.Under this environment, each camera array unit 4 is connected with camera array wireless energy control units 6 by camera array control linkage line.After each camera array unit 4 is taken simultaneously, the common photo that camera array wireless energy control units 6 obtains shooting uploads to data processing terminal 10, after computing, obtains 3-D view.
Special lighting mode of the present invention refers to that reflective curtain enclosure wall 1 is arranged on system outermost layer, reflective curtain enclosure wall 1 by the light reflection of photography luminaire 2 to soft light cover 3, by soft light cover 3 by softization of light, and then make the light on object under test surface uniform and stable, internal system is provided with 4-12 platform photography luminaire, and the number of photography luminaire determines according to the size in b district, photographed region.
Described camera array unit 4 is made up of 6-12 portion digital camera, and internal system is provided with 3-12 group camera array unit.It is characterized in that: described camera array unit 4 is placed in soft light cover 3 with annular array form, in each camera array unit 4 horizontal directions, be equipped with two cameras, on vertical direction, arrange in multilayer mode; Between described camera array unit, be connected with camera array wireless energy control units 6 by camera array control linkage line 9, data processing is taken when 10 ends carry out camera array by wireless controller eventually.
Described photography luminaire 2 is connected with wireless energy control units 8, and data processing terminal 10 is by the brightness height of controlled in wireless photography luminaire.
Effect of the present invention and benefit are: 1. the present invention adopts ordinary digital camera array to gather object information, and acquisition time is 0.05 second, and the image texture exquisiteness obtaining; 2. the present invention adopts camera array wireless energy control units 6 to realize the controlled in wireless of image processing terminal to camera array 4, convenient and swift; 3. the present invention adopts camera array wireless energy control units 6 to realize the information wireless that camera array 4 gathers and is transferred to image processing terminal, and efficiently and accurately has been avoided the chaotic mistake of information and distortion; 4. system of the present invention does not need the background calibration before image information collecting, simple to operate.
