Embodiment 1

[0103] refer to Figure 1 to Figure 6 , Figure 10-Figure 14 , a fast panoramic stereo camera measurement device, comprising a omnidirectional visual sensor, a panoramic color modulated light generator and a microprocessor for three-dimensional stereo camera measurement of omnidirectional images, the omnidirectional visual sensor and the panoramic color The modulated light generator is configured on the same axis, and the omnidirectional vision sensor is connected with the microprocessor; the omnidirectional vision sensor includes a camera unit 6 and a first hyperboloid catadioptric unit; A hyperboloid catadioptric unit comprises a first hyperboloid mirror 2, a first upper cover 1, a first support rod 3, a transparent glass surface 4 and an additional lens frame 5, the upper part of the first hyperboloid mirror 2 is connected to the first upper The cover 1 is connected, the bottom center of the first hyperboloid mirror 2 is connected to the upper end of the first support rod ...

Embodiment 2

[0182] refer to figure 1 , figure 2 , Figure 7 , Figure 10-Figure 14 In this embodiment, in the connection mode between the panoramic color modulated light generator and the omnidirectional visual sensor, a face-to-face connection is adopted here; the face-to-face connection is to connect the camera unit 6 on the omnidirectional visual sensor It is connected with the light source fixing frame 8 on the panoramic color modulating light generator through a connecting piece. In this connection, the convex surfaces of the two hyperboloid mirrors with the same parameters face the convex surfaces, and the two hyperboloids must be guaranteed The axes of the mirror surfaces 2 and 22 are coincident, such as Figure 7 shown; from Figure 7 It can be seen that the face-to-face fast panoramic stereo camera measurement device has the longest baseline distance B and the largest stereo vision measurement range.

[0183] The other structures and working process of this embodiment are ...

Embodiment 3

[0185] refer to figure 1 , figure 2 , Figure 8 , Figure 10-Figure 14 In this embodiment, in the connection mode between the panoramic color modulated light generator and the omnidirectional visual sensor, what is used here is a face-to-back connection, that is, the upper side is the panoramic color modulated light generator and the lower side is the omnidirectional visual sensor connection mode; The face-to-back connection method is to connect the light source fixing frame 8 on the panoramic color modulation light generator with the upper cover 1 on the omnidirectional vision sensor through a connecting piece. Make the convex surface of the second hyperboloid mirror surface 22 on the panoramic color modulation light generator face the concave surface of the first hyperboloid mirror surface 2 of the omnidirectional vision sensor, and ensure that the axes of the two hyperboloid mirror surfaces 2, 22 coincide ,Such as Figure 8 Shown; The baseline distance B and the stere...
