Description
Technical field
The utensil used is rebuild in a kind of three-dimensional reduction of system of the present invention, specifically relates to a kind of adjustment structure of taking frame in three-dimensional reduction installation Image Acquisition instrument for shooting and interference of light source.
Background technology
Three-dimensional reconstruction is one of problem of current global range most attractive force, and throwing huge fund in countries in the world is in pursuit and improve reconstruction effect, the reconstruction precision more increased more true to nature, 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 three-dimensional object image, the method and apparatus that digitized measurement and reduction are rebuild.
Conventional method carries out imaging by least two strict pinpoint imageing sensors to same object to obtain two corresponding width images and send computing machine to, calculate according to optical imaging concept and determine that space object is taken up an official post the three-dimensional coordinate geometric parameter of a scaling point, 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 that two cameras are accurately located, keep two camera transfixions, the distance of both Accurate Calibrations, relative X, Y, Z-direction angle, but a large amount of parts machining of two cameras, assembling, assembling and shooting etc. factor, error can be had, through the effort of many decades, the precision of distance and angle calibration is contracted to micron by millimeter, to tens of silk, be close to the ultimate value on mechanic concept, difficult have breakthrough.A bit error mutual between camera, causes the object restoring data error measured, calculate to be amplified by very large multiple, rebuilds object and is difficult to avoid distortion, distortion.
Therefore, this area is striving to find exploration better reduction reconstruction measure.
Number of patent application 201210280413.0 " a kind of shooting three-dimensional reduction method for reconstructing " and number of patent application 201210281322.9 " a kind of digital camera follow shot three-dimensional rebuilding method ", propose a kind of method of extrinsic calibration, namely a digital camera and one are arranged on the interference of light source of digital camera sidepiece, size and the distance at position is rebuild according to object or object wish, and the precision of reduction, DIGITAL-MODUL-R (CCD) density of choosing a digital camera and digital camera lens focal length, the mutual spacing of configuration digital camera and interference of light source and angle, reach digital camera and the interference of light source shooting image exist coplanar, reach the DIGITAL-MODUL-R (CCD) being reduced object image areas area and at utmost occupying digital camera.Need in relevant photographing program Image Acquisition instrument and interference of light source no matter up and down can be flexible on a shooting frame do the adjustment of various Distance geometry angle.Especially, such as when taking the figure of buddha painted sculptures in reduction the Dunhuang Caves, grottoes finite volume, shooting narrow space, the distance that reference object is left in digital camera and interference of light source is very near, and therefore digital camera and interference of light source must have very large angular setting scope.In order to full backup painted sculptures, after many occasion digital cameras and interference of light source also need to stretch into the oxter of painted sculptures, arm, the place such as trailing flank goes shooting, now need digital camera and interference of light source to have very long elastic distance at narrow space, and extend into narrow and small, back space personnel and cannot can realize automatically controlled or remote control at a distance etc. during directly manual setting shooting angle.Logarithmic code camera and interference of light source are installed, the particular/special requirement of configuration, adjustment is that prior art does not provide, and cannot realize, in order to realize the three-dimensional reconstruction of special object better, in the urgent need to providing a kind of comprehensive, the one shooting shelf structure in nimble motor-driven Image Acquisition instrument and interference of light source.
To realize being fixed on Image Acquisition instrument on shooting frame and interference of light source in upper and lower, the omnibearing rotation in left and right at narrow space, prior art is almost a blank, or mechanism is huge, or complex structure, or use dumb inconvenience automatically not control, in the urgent need to there being improvement behave.
Summary of the invention
The object of this invention is to provide shooting reduction object shooting frame in three-dimensional reduction is rebuild, Image Acquisition instrument and interference of light source can comprehensive dexterity be rotated, and the simple a kind of mechanism arrangement of structure, particularly in narrow space occasion, adopt simple and reliable structure to be achieved.
The object of the invention is to be achieved through the following technical solutions:
