Embodiment 1

[0045] refer to Figure 1-10 , a color panoramic projection light source for active three-dimensional panoramic vision, including a spherical substrate and multiple groups of ultra-high-brightness LEDs with different central wavelengths of light emission, the spherical substrate is used to combine and fix ultra-high brightness LEDs with different central wavelengths of light emission For high-brightness LEDs, first process the spherical substrate into a spherical body, the center of the spherical body is a hollow spherical body, and the middle of the sphere is a hollow cylinder; then from the largest diameter of the spherical surface from the In the longitude direction, it is equally divided by a certain angle. For example, it is divided into 36 equiangular intervals, then each equiangular interval is 10°; then from the maximum diameter of the spherical surface, the equiangular interval is 10° from the latitude direction. Carry out equal divisions, the number of equal division...

Embodiment 2

[0099] refer to Figure 1 to Figure 10 In terms of the selection of the spectral range of the LED light source in this embodiment, in some special occasions, if the color panoramic projection light source is required to emit the infrared spectrum, the spectral range of the LED device is selected at 700nm-2000nm.

[0100] Other structures and working processes of this embodiment are the same as those of Embodiment 1.

Abstract

The invention relates to a color panoramic projective light source for initiative three-dimensional panoramic vision, which comprises a spherical body base plate and a plurality of groups of ultra high-bright LEDS with different luminous wavelengths, wherein the spherical body base plate is used for combining and fixing the ultra high-bright LEDS with different luminous wavelengths so as to realize the color panoramic projective light source with a single projective central point and ultra high-bright, and can provide an initiative panoramic structural light source for an initiative three-dimensional panoramic vision sensor; the color panoramic projective light source is combined with the panoramic vision sensor for realizing the panoramic vision sensor which can obtain scenery depth and a color corresponding diagram which are corresponding to real objects; therefore, the light panoramic projective light source can reduce computing resource, quickly finishes measurement, has good realtime, strong practicability and high robustness.

Description

technical field [0001] The invention relates to the application of LED light source, optical technology and computer vision technology in stereo vision measurement, in particular to a projection light source of an active three-dimensional stereo panorama 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 thre...
