Description
Technical Field
The present invention relates to the field of stereoscopic imaging technologies, and in particular, to a stereoscopic imaging apparatus and a stereoscopic imaging method.
Background
With the increasing maturity of digital imaging technology, stereo imaging technology is rapidly developing. The stereo imaging technology is mainly realized by utilizing the parallax characteristics of two eyes of a person, and the specific realization mode mainly comprises the following steps: a color separation method, a light separation method, a time division method, a grating method, and the like. Although there are various specific implementation manners, the principles of all the implementation manners are similar, namely: two parallel cameras are used for synchronously shooting two pictures with slight horizontal parallax, and the two cameras respectively represent the left eye and the right eye of a person. When in showing, the two pictures are respectively arranged in a left-eye showing device and a right-eye showing device, the left-eye showing device and the right-eye showing device synchronously operate, and the pictures are simultaneously shown to form a double-shadow image comprising a left-eye image and a right-eye image. Viewers have access to some special devices, such as: the left eye and the right eye can be respectively superposed on the retina through the convergence function of the two eyes, and the brain nerves generate a three-dimensional visual effect.
The above description illustrates: whichever implementation is used, the key is that it must be made that the left and right eye of the viewer see no exactly the same image, namely: the picture corresponding to the left eye is observed only by the left eye, and the picture corresponding to the right eye is observed only by the right eye. Thus, a camera with a stereoscopic effect must have two cameras to image and process the images. However, the existing shooting device has some disadvantages, which mainly appear in the following three aspects:
first, the two cameras cannot be identical due to physical properties, such as: focal lengths are not completely the same, so that the two cameras are not completely consistent in focusing performance, and the definition of left and right videos is not completely consistent, and finally image imaging blurring is caused.
Secondly, there is an error in the installation and alignment of the two cameras, which results in that the images shot by the two cameras are not completely consistent in the horizontal and oblique directions of the viewing angles, and further causes deviation in image processing, and finally causes image ghost.
Finally, the difference in electrical performance of the respective image sensors in the two cameras causes the photographed images to be inconsistent in characteristics such as brightness, contrast, chromaticity, gray scale and the like, thereby causing visual difference of the left and right images, and finally causing the phenomena of visual vertigo, image blurring and the like of audiences.
Fig. 1 is an abstract drawing of a chinese patent application No. 200910104853.9, namely, "a stereo camera device and method", which discloses a stereo camera device, using a precise optical imaging structure to ensure consistency on an optical path, and using only one image sensor to receive two images, however, as seen from fig. 1, the patent has important technical defects, which are mainly shown in the following:
first, the first optical imaging lens group 111 and the second optical imaging lens group 112 are far away from the image sensor 120. When a long shot is shot, the optical imaging lens group is generally required to be closer to the optical path of the image sensor according to the lens imaging rule, otherwise, the image is blurred, so that the device and the method disclosed by the patent cannot shoot the long shot;
secondly, since all the light rays of each light ray emitted by the object can be imaged only after being reflected by the same angle of the plane mirror, the patent does not fully disclose the technical details that the positions of the mirror surfaces of the first plane mirror 114, the second plane mirror 115 and the third plane mirror 113 have a certain relationship, and thus, the imaging on the image sensor 120 may not be performed, and the purpose of shooting cannot be achieved at all.
