Description

Three-dimensional is reduced into as the connection control unit with small-sized recording instrument
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 connection control 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.
