Embodiment 1

[0129] Referring to Figure 5, Figure 6 , Figure 7 , Fig. 11, a kind of all-round monitoring vision device with the function of considering the feeling in the heart, this device is an upper fixed hyperboloid type all-round vision device, including a catadioptric mirror hanging straight down, a transparent cylinder, a camera, and a mounting bracket , the catadioptric mirror is located on the top of the transparent cylinder, the bottom of the transparent cylinder is provided with a reflective flat mirror, the middle of the described catadioptric convex mirror is provided with a through hole, and the camera is located at the catadioptric The top of the convex mirror is provided with a black conical body whose diameter gradually decreases between the reflecting flat mirror and the refracting mirror, and the conical body is fixed on the middle part of the reflecting flat mirror. The central positions of the lens of the cone, the cone and the camera are on the same central axis, a...

Embodiment 2

[0174] Referring to Figure 5, Figure 6 , Figure 7 , Fig. 11, the present embodiment is an upper fixed type non-deformable omni-directional visual device in the horizontal direction: the catadioptric mirror is a catadioptric lens without deformation in the horizontal direction, and the projection center C of the camera is above the horizontal scene at a distance h from the horizontal scene , the vertex of the catadioptric lens is above the projection center, at a distance from the projection center zo, and the coordinate system is established with the camera projection center as the coordinate origin. The surface shape of the catadioptric lens is expressed by the z(X) function, and the distance from the image center point in the image plane The pixel q of ρ receives the light reflected from the point O of the horizontal scene, the distance from the Z axis d, and the point M of the catadioptric lens. No distortion in the horizontal scene requires that the horizontal coordinate...

Abstract

The invention comprises a vertically hanging reflector, a transparent barrel, a video cameral, and a mounting rack having an upper securing structure. The reflector is located on the upper portion of the transparent barrel; the lower portion of the transparent barrel there is a flat reflector; in the center of convex mirror of the reflector there is a through hole; the video camera is located above the convex mirror of the reflector; a black taper whose diameter gradually goes to small is set between the flat reflector and the reflector, and the taper is secured in the center of the flat mirror; the reflector, flat reflector, taper and lens of video camera all are set on a same central axis; the output of the video camera is connected to a image processing MPU. The invention also comprises an omnidirectional vision sensor.

Description

(1) Technical field [0001] The invention belongs to the application of optical technology, computer image processing technology and embedded software and hardware technology in video monitoring equipment, and is mainly applicable to various remote video monitoring equipment, especially an all-round monitoring visual device with the function of considering the feeling in the heart . (2) Background technology [0002] In modern society, electronic monitoring equipment has been widely used in urban traffic arteries, high-end office buildings, residential areas, and large shopping malls and supermarkets. Reasonable use of electronic monitoring technology can effectively maintain public safety and provide a strong guarantee for social security. [0003] Various video surveillance equipment currently on the market are typically various cameras. When taking pictures, the camera lens of the equipment must be aimed at the camera target. The range of images captured by this camera met...
