Abstract

The invention discloses an active three-dimensional stereoscopic panoramic vision sensor with equiangular distinguishing ratio, comprising a panoramic vision sensor with equiangular distinguishing ratio, a color panoramic vision projection light source and a microprocessor for the three dimensional stereoscopic camera measurement of omni-directional image. The panoramic vision sensor with the equiangular distinguishing ratio and the color panoramic vision projection light source are arranged on the same axial lead; the panoramic vision projection light source is formed by assembling a plurality of sets of LEDs with different luminous central wavelength and ultra-high brightness according to a single transmitting centre point, so as to provide an active panoramic structure light source forthe panoramic vision sensor with equiangular distinguishing ratio; and the color panoramic vision projection light source is combined with the panoramic vision sensor with equiangular distinguishing ratio so as to be capable of obtaining a scenery depth and color corresponding diagram which is corresponding to a practical object one by one on an imaging plane. The active three-dimensional stereoscopic panoramic vision sensor can reduce computation, fast completes measurement, and has good instantaneity, strong practicability, high robustness, and the equiangular distinguishing ratio.

Description

technical field [0001] The invention relates to the application of LED light source, optical technology and computer vision technology in three-dimensional stereo vision measurement, in particular to an active three-dimensional stereo panoramic vision sensor. Background technique [0002] In terms of video image information acquisition, the quality of video signal sources has always been the bottleneck of computer vision. The ideal acquisition device for computer vision signal sources is a visual sensor that can obtain a one-to-one correspondence with the actual object depth and color map. Obviously, it is impossible to obtain the depth and color map corresponding to the actual object only by a two-dimensional imaging plane visual sensor, and it is possible to realize this ideal stereoscopic vision sensing only with other technical support. [0003] The current visual sensor technology uses a two-dimensional imaging plane image to express an image in an actual three-dimensio...
