Embodiment 1

[0098] refer to Figure 1~5 , Figure 7-9 , Figure 11 , Figures 14 to 15 , an active three-dimensional panoramic vision sensor based on a full-color panoramic LED light source, including an omnidirectional vision sensor, a panoramic color structured light generator, and a microprocessor for performing three-dimensional camera measurements on omnidirectional images, the omnidirectional The visual sensor and the panoramic color structured light generator are configured on the same axis; the omnidirectional visual sensor includes a first hyperbolic mirror surface 2-1, a first upper cover 1-1, a first transparent semicircular Outer cover 3-1, first lower fixing seat 4-1, camera unit fixing seat 5-1, camera unit 6, first connecting unit 7-1, upper cover 8, as attached figure 1 As shown; the first hyperboloid mirror surface 2-1 is fixed on the first upper cover 1-1, and the first connecting unit 7-1 connects the first lower fixing seat 4-1 It is integrated with the first tran...

Embodiment 2

[0152] refer to Image 6 , Figure 12 , Figures 13 to 14 , this embodiment adopts a back-to-back connection in the connection mode between the panoramic color structured light generator and the omnidirectional vision sensor, as shown in the accompanying drawing Image 6 , attached Figure 12 As shown, the first upper cover 1-1 of the omni-directional vision sensor is connected with the second upper cover 1-2 of the panoramic color structured light generator; this connection method combines two hyperboloid mirrors with the same parameter The concave surface faces the concave surface, and it is necessary to ensure that the axis lines of the two first hyperboloid mirror surfaces 2-1, 2-2 coincide, such as Image 6 shown; from Image 6 It can be seen that the back-to-back active 3D stereo panoramic vision sensor based on full-color panoramic LED light source has the shortest baseline distance B and the smallest stereo vision measurement range, but its structure is the most co...

Embodiment 3

[0155] refer to Figure 10 , Figure 14 ~ Figure 15 , this embodiment adopts the face-to-back connection method between the panoramic color structured light generator and the omnidirectional vision sensor, as shown in the attached Figure 10 As shown, the second upper cover 1-2 of the panoramic color structured light generator is connected with the first connection unit 7-1 of the omnidirectional vision sensor; The convex surface faces the concave surface, wherein the convex surface is the first hyperboloid mirror surface 2-1 of the omnidirectional vision sensor, and the concave surface is the second hyperboloid mirror surface 2-2 of the panoramic color structured light generator, while ensuring two first hyperboloid surfaces The axes of the mirror surfaces 2-1 and 2-2 coincide; the baseline distance B and the stereo measurement range of the active three-dimensional panoramic vision sensor based on the full-color panoramic LED light source of this face-to-back type are betwee...

Abstract

The invention relates to an active three-dimensional panoramic view vision sensor based on a full color panoramic view LED light source, which comprises an omnibearing vision sensor, a panoramic view optical generator with a colorful structure and a microprocessor for performing three-dimensional shooting measurement on an omnibearing image. The omnibearing vision sensor and the panoramic view optical generator with the colorful structure are arranged on the same axial lead; the omnibearing vision sensor comprises an image unit and a hyperboloid catadioptric unit; the panoramic view optical generator with the colorful structure comprises an LED optical generator unit with a colorful structure and a hyperboloid catadioptric unit; a hyperboloid catadioptric mirror surface and a hyperboloid refraction mirror surface have same image parameters; and the microprocessor comprises an LED light source control unit, a video image reading module, a special information calculation module and a three-dimensional image reconstruction module. The active three-dimensional panoramic view vision sensor can reduce the calculation, quickly finish the measurement, and has good real-time property and strong practicability.
