A kind of multi-viewpoint three-dimensional photographic apparatus with automatic aggregation featureTechnical field
The present invention relates to a kind of photographic apparatus, specifically, is a kind of multi-viewpoint three-dimensional photographic apparatus with automatic aggregation feature.
Background technology
Stereoscopic shooting refers to the three-dimensional a kind of method for imaging of performance scenery, wherein many camera modes refer to that use two or more camera or video camera are taken simultaneously when the films and television programs such as shooting picture and video, each camera lens can both carry out independently finding a view simultaneously, thus at synchronization to the photo of same multiple different visual angles of scene shot or video, then the three-dimensional file of logarithmic code synthesizes, and finally will become to have photo or the video of 3-D effect.
" five lens stereo video cameras " that the Shanghai sea-gull Camera Factory of selling in the market produces, " four-barrel stereocamera " that Xiongba Stereo-optical Equipment Co., Ltd., Jiangmen produces, and " three-lens stereocamera " that the three-dimensional U.S. image Science and Technology Ltd. in Zhuhai produces all belongs to many lens stereo cameras.The camera lens of these cameras is all linearly arrangement, and namely the optical axis of each camera lens is arranged parallel to each other.Fig. 1 is the optical axis arrangement schematic diagram of the camera lens of five known lens digital stereocameras.But because the optical axis of each camera lens is parallel to each other, its each camera lens can only do plane focusing, and can not rotate, thus make multi-picture time main by photography thing and background not in same visual angle, just unclear at the whole picture of later stage synthesis rear backdrop, stereoeffect is desirable not to the utmost.
In addition, Chinese patent CN2501076 discloses a kind of Multi-lens digital stereoscopic camera on July 11st, 2002, it comprises housing, be arranged on the stepper motor or the manual adjustments focus button be connected with housing and fixed support that are fixedly connected with housing in housing, and one group of varifocal mirror, be wherein the varifocal mirror that can move in parallel at the varifocal mirror of recording instrument axis both sides, this camera lens that can move in parallel varifocal mirror by cam pack and camera lens stationary platform in being rotationally connected shape.Although this invention take into account the benefit of remittance Jiao that camera lens rotational is reached, but it is realized by the mechanical transmission structure of cam, slide bar and rolling bearing, therefore the multiple camera lenses in one group varifocal mirror can not realize synchronous rotary, the adverse consequences brought thus is: when taking stereoscopic photograph, each camera lens can not simultaneous polymerization main by photography thing on same point, when post-production is synthesized main by photography thing with background not in identical visual angle, whole image frame is just unclear, and stereoscopic sensation is not strong, stereoeffect is undesirable.Fig. 2 is the optical axis arrangement schematic diagram of the rotating camera lens of five known lens digital stereocameras.
Therefore known Multi-lens digital stereoscopic camera also exists above-mentioned all inconvenience and problem.
