Description
Technical field
The utility model relates to the stereoscopic imaging technology field, is meant a kind of stereo photographic device especially.
Background technology
Along with reaching its maturity of digital imaging technology, stereoscopic imaging technology is development fast.Stereoscopic imaging technology mainly utilizes the parallax characteristic of two eyes of people to realize that its specific implementation mainly comprises: look point-score, light point-score, time-sharing procedure and raster method etc.Though specific implementation has multiple, the principle of all implementations is similar, utilizes two video cameras of settling side by side that is:, shoots two slightly pictures of horizontal parallax synchronously, and this two cameras is commissarial left eye and right eye respectively.During projection, two pictures are respectively charged into left eye projecting device and right eye projecting device, left eye projecting device and the run-in synchronism of right eye projecting device are come out picture presentation simultaneously, form the slur image that comprises left-eye image and eye image.The beholder is by some specific installations, and for example: polaroid glasses etc. make left eye can only see left-eye image, right eye can only be seen eye image, aggregation feature by eyes again, respectively that left-eye image, eye image is superimposed on retina, produce the visual effect of 3 D stereo by cerebral nerve.
More than describe explanation: no matter adopt which kind of implementation, key is to accomplish that beholder's left eye and the image that right eye is seen can not be identical, that is: only observed by left eye corresponding to the picture of left eye, is only observed by right eye corresponding to the picture of right eye.So, the filming apparatus with stereoeffect must have two cameras and carry out imaging, and image is handled.But there are some shortcomings in existing filming apparatus, mainly shows following three aspects:
At first, two cameras are because physical property can not be identical, such as: focal length is incomplete same, therefore, can cause two cameras not quite identical on focusing performance, and then cause left and right sides video definition not quite identical, finally cause image imaging fuzzy.
Secondly, there is error in two cameras installing in the contraposition, cause image that dual camera takes in the level at visual angle with not quite identical on tilting, and then deviation occurs when causing Flame Image Process, finally cause image to produce ghost image.
At last, there is the difference on the electrical property in separately imageing sensor in the dual camera, cause taken image inconsistent on characteristics such as brightness, contrast, colourity, GTG, and then cause the left and right sides image vision difference to occur, finally cause spectators to produce phenomenons such as vision is dizzy, image blurring.
Fig. 1 is the Figure of abstract of 200910104853.9 Chinese patent " a kind of stereo photographic device and method " for application number, this patent disclosure a kind of stereo photographic device, guarantee consistance on the light path with the precision optics imaging arrangement, only receive the technology of two-way image with an imageing sensor, but, as seen from Figure 1, there is the important technology defective in this patent, mainly shows:

Secondly, because all light has only through just can imaging after the reflection of level crossing equal angular in every bundle light of sending of object, there are certain ins and outs that concern in the position that this patent does not fully disclose the minute surface of first plane mirror 114, second plane mirror 115 and the 3rd catoptron 113, so, may cause can't imaging on imageing sensor 120, thereby can't realize the purpose of taking at all.
