Description
Technical field
The present invention relates to a kind of three-dimensional reduction and rebuild the utensil used, be exactly specifically a kind of can meet small space and the not good situation of light conditions under three-dimensional carried out to subject be reduced into as small-sized recording instrument for shooting.
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.
