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 an axis-shifting stereo camera. In a tilt-shift stereo camera, the left and right lens groups, which are independent, identical, and whose centerlines are parallel to each other, move along the horizontal direction by a distance of L=T÷(2A) towards directions opposite to each other. The two images with different viewing angles obtained by the tilt-shift stereo camera not only have no trapezoidal distortion, but also have a linear relationship between the stereo depth of an object of interest and the stereo depth of the convergence point of the stereo image of the object of interest in the real scene. The invention also discloses a same-screen chip, which solves the problem of the separation of the focal plane of the eye and the image plane of the stereoscopic image, and a healthy stereoscopic player, which makes the measurement process of the stereoscopic image more intelligent, simpler and more accurate. The invention can be applied to medical endoscope, cavity mirror, industrial endoscope, stereo camera, stereo measurement and other stereo image production and application fields.

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...
