Embodiment Construction
[0109] The specific mode of carrying out the present invention represents an example in which the present invention is embodied, and corresponds to the contents and specific matters in the claims and the specification. The present invention is not limited to the embodiment, and can be embodied in various embodiments without departing from the gist of the present invention. The illustrated cases in all schematic diagrams are all examples of the described multiple implementable technical solutions.
[0110] Picture 1-1 What is shown is a schematic diagram of a stereoscopic image acquisition space. The left and right cameras 1 and 2 rotate around the center of the camera lens to the inner corner direction, until the centerlines of the left and right cameras 1 and 2 converge on an object of interest 5 in the real scene and start shooting. The left and right images of the object of interest are imaged at the center of the imaging surfaces of the image sensors 3 and 4 of the left...

The invention discloses a tilt-shift stereo camera. A left image and a right image, collected by a left lens group 1 and a right lens group 2 which are arranged in parallel in the tilt-shift stereo camera, of a concerned object 5 located on the central axis of the stereo camera are imaged on the imaging surfaces 3 and 4 of the left image sensor and the right image sensor respectively. When a concerned object 5 moves, the same-screen chip synchronously translates the left lens group 1 and the right lens group 2 along the horizontal direction, so that the left image and the right image of the concerned object 5 are respectively imaged at the centers of the imaging surfaces 3 and 4 of the left image sensor and the right image sensor. After the left lens group 1 and the right lens group 2 are translated, the stereoscopic image convergence point of the object 5 of interest is kept on the screen, and the stereoscopic depth of the object 5 of interest and the stereoscopic depth of the stereoscopic image convergence point of the object 5 of interest satisfy a group of linear mathematical formulas. The invention solves the problems of non-linear distortion and screen-out of the stereoscopic image and separation of the focus plane of the eyes and the image plane of the stereoscopic image, and is applied to the fields of endoscopes, endoscopes, stereoscopic measurement, stereoscopic cameras, stereoscopic image processing and other stereoscopic image manufacturing and application.
Description
technical field [0001] The invention relates to a dual-lens stereo camera, stereo image linear optical technology, stereo image acquisition and playback technology, stereo image positioning, tracking and measurement technology. Background technique [0002] There are unavoidable trapezoidal distortion, nonlinear distortion and out-of-screen problems in two kinds of traditional stereoscopic image shooting methods. The stereoscopic image effect obtained by the convergence method is the same as the way and effect that the eyes observe an object of interest by turning the eyeballs. However, when the object of interest moves, the left and right cameras cannot track the moving object of interest through synchronous rotation to the inner or outer corners, and converge and maintain the centerlines of the left and right lenses on the object of interest. The image has keystone distortion. The stereoscopic image effect obtained by the parallel method is the same as the way and effect...
