Description
Technical field
The present invention relates to a kind of three-dimensional reduction and rebuild the utensil that uses, specifically be exactly a kind of can satisfy in small space and the not good situation of light source condition subject is carried out the interference of light source unit that three-dimensional is reduced into picture small-sized recording instrument for shooting.
Background technology
Three-dimensional reconstruction is one of the most attractive problem of present global range, and countries in the world are thrown huge fund and pursued and improving reconstruction effect more true to nature, the reconstruction precision of more increasing, rebuild speed more fast.
So-called hologram three-dimensional reconstruction technique is based on computer stereo vision and computer graphics and optical imaging concept, obtains the three-dimensional object image, the method and apparatus that digitized measurement and reduction are rebuild.
Conventional method is by at least two strict pinpoint imageing sensors same object to be carried out two corresponding width of cloth images of imaging acquisition to send computing machine to, according to the take up an official post three-dimensional coordinate geometric parameter of a scaling point of optical imaging concept calculative determination space object, set up digital model by computing machine, the original is rebuild in reduction then.
In order to obtain the object Reduction Body of high-fidelity, prior art requires two cameras accurately to locate, keep two camera transfixions, both distances of Accurate Calibration, relative X, Y, Z orientation angle, but a large amount of parts machining, assembling, assembling and shooting of two cameras etc. factor, can there be error, through the effort of many decades, the precision of distance and angle calibration is contracted to micron by millimeter, to tens of silks, be close to mechanical notional ultimate value, difficult have a breakthrough.Mutual a bit error between camera, the object restoring data error that causes measuring, calculating is amplified by very large multiple, rebuilds object and is difficult to avoid distortion, distortion.
Therefore, this area is striving to find better reduction reconstruction measure of exploration.
Number of patent application 201210280413.0 " the three-dimensional reduction of a kind of shooting method for reconstructing " and number of patent application 201210281322.9 " a kind of digital camera follow shot three-dimensional rebuilding method ", a kind of method of extrinsic calibration has been proposed, i.e. a number of units code camera and an interference of light source that is arranged on the digital camera sidepiece, size and distance according to object or material desire reconstruction portion being shot position, and the precision of reduction, the DIGITAL-MODUL-R of choosing a digital camera (CCD) density and digital camera lens focal length, configuration digital camera and mutual spacing and the angle in interference of light source, reach digital camera and interference of light source photographic images and exist coplanarly, reach and be reduced the DIGITAL-MODUL-R (CCD) that object position imaging area at utmost occupies digital camera.In relevant photographing program, need Image Acquisition instrument and interference of light source to take the adjustment that no matter can make up and down various distances and angle on the frame at one flexiblely.Especially, during such as the figure of buddha painted sculptures in taking the reduction the Dunhuang Caves, the grottoes finite volume is taken narrow space, and it is very near that the distance of reference object is left in digital camera and interference of light source, so digital camera and interference of light source must have very large angular setting scope.For the full backup painted sculptures, after many occasion digital cameras and interference of light source also need to stretch into the oxter, arm of painted sculptures, trailing flank etc. locates to take, need digital camera and interference of light source at narrow space very long elastic distance to be arranged this moment, and extend into narrow and small, space, back personnel and can realize remote automatically controlled or remote control etc. can't directly manual setting shooting angle the time.Being used for the digital camera of taking and being used for providing the interference of light source of pickup light environment in the existing three-dimensional reduction Image-forming instrument all is split-type structural, can't satisfy small space like this and luminous environment than the shooting work under the dark condition, in order to realize better to this small space with than the three-dimensional reconstruction of special object under the half-light environmental baseline, can satisfy narrow and small environment and luminous environment than the instrument of taking under the dark condition in the urgent need to a kind of small volume, maneuverability.
