Problems solved by technology

[0006] The mainstream binocular stereo image measurement method is a technology based on the convergence method, but the trapezoidal distortion and trigonometric functions in the convergence method cause additional errors to the stereo image measurement results

Embodiment Construction

[0123] The detailed description of the present invention shows an example of the embodiment of the present invention, 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 the schematic diagrams are examples of the multiple implementable technical solutions described above.

[0124] Picture 1-1 What is shown is a schematic diagram of a top view of a dual-prism tilt-shift stereo camera with a single image sensor. In the figure, there are two independent and identical lens groups (a) and (b) on the left and right. After the axis shift, the two lens groups (a) and (b) are simultaneously translated towards each other by a distance of L, and the centerlines of the two lens groups (a) and (b) are translated from the position of 7 before the axis shift To the po...

Abstract

The invention discloses a shaft-shifting stereo camera. A left lens group and a right lens group which are independent from each other and are the same with each other and parallel to the center linein the shaft-shifting stereo camera translate for a distance of L = T / (2A) along the horizontal direction and towards the opposite direction. Two images with different visual angles obtained by the tilt-shift stereo camera have no trapezoidal distortion, and the relationship between the stereo depth of an object of interest in a real scene and the stereo depth of a stereo image convergence point of the object of interest is a linear relationship. The invention further discloses a same-screen chip, the problem that the focal plane of the eyes is separated from the image plane of the three-dimensional image is solved, and the healthy three-dimensional player enables the three-dimensional image measurement process to be more intelligent, simpler and more accurate. The camera can be applied tothe fields of medical endoscopes, endoscopes, industrial endoscopes, stereo cameras, stereo measurement and other stereo image manufacturing and application.

Description

technical field [0001] The invention relates to a double-lens stereo camera, a linear optical design of a stereo image, a technology for superimposing the focal plane of eyes and an image plane of the stereo image, a measurement technology of the stereo image and a positioning and tracking technology of the stereo image. Background technique [0002] Two cameras usually use the convergent or parallel method to capture stereoscopic images. The stereoscopic image effect obtained by the convergence method is the same as the method and effect of observing an object of interest by the eyes, but the two images obtained have the problem of trapezoidal distortion. The method and effect of an object of interest obtained by the parallel method are the same as the way and effect of the eye observing an object of interest located at infinity. However, when the distance of the object of interest is limited, the stereoscopic effect of the stereoscopic image of the object of interest obta...
