Same-screen stereo camera

Abstract

The invention discloses a same-screen stereo camera. A left image and a right image, collected by a left lens group 1 and a right lens group 2 in the same-screen stereo camera, of a concerned object 5 located on the central axis of the stereo camera are respectively imaged on imaging surfaces 3 and 4 of a left image sensor and a right image sensor and then are output to an image processor. A same-screen chip in the image processor synchronously translates a left image and a right image of an input concerned object 5 in the horizontal direction, so that the left image and the right image of the concerned object 5 are located in the centers of the left new image and the right new image which are translated respectively. After the left image and the right image 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 double-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 the two 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 th...
