Eagle eye-imitated intelligent visual sensing node and work method thereof

Abstract

The invention relates to an eagle eye-imitated intelligent visual sensing node which comprises a wide-angled camera, two PTZ cameras, an embedded type processor and a PTZ controller, wherein the wide-angled camera and the two PTZ cameras are positioned on a hardware platform, the wide-angled camera is arranged in the middle and fixed in position, the two PTZ cameras are arranged at two sides, the wide-angled camera and the two PTZ cameras are connected with the embedded type processor by signal wires, an acquired image is processed by the embedded type processor, the embedded type processor is used for controlling the PTZ cameras by the PTZ controller, and the two PTZ cameras can be adjusted under the control of the embedded type processor. After the eagle eye-imitated intelligent visual sensing node and a work method of the eagle eye-imitated intelligent visual sensing node are adopted, a visual range can be expanded to reach about 180 degrees, a suspicious target can be conveniently detected and positioned in a glancing way within a large range in a manner of variable resolution, and the target can be elaborately analyzed and recognized with high resolution.

Description

technical field [0001] The invention relates to an imitation eagle eye intelligent vision sensing node and a working method, belonging to the field of video analysis technology and bionic technology Background technique [0002] Among all animals, eagle eyes are among the best in observing animals, and are famous for their wide vision and keen eyesight. Even an eagle soaring at an altitude of two or three thousand meters can find and capture targets from many relatively moving and complex backgrounds at once with its eyes. The reason why an eagle can accurately identify targets on the ground at an altitude of several thousand meters is determined by the particularity of its eye structure and its visual principles. Therefore, analyzing the principle of eagle eye vision and establishing the eagle eye vision model have broad application prospects in the field of bionic vision. [0003] Vision is a basic function of humans and some animals and an important information receivin...

Problems solved by technology

[0004] In view of the shortcomings of the current visual sensor, such as insufficient visual range, low utilization rate of image information, and fixed, single, and difficult-to-change functions of some intelligent visual sensors, the purpose of this discovery is to provide a node and working method of imitating eagle-eye intelligent visual sensors. Using video analysis and image processing technology, imitating the mechanism and mechanism of the eagle eye to perceive the environment, the acquired three-way image is processed and analyzed, and finally the online programming function is added to facilitate users to quickly customize their own needs and expand the application range of intelligent vision sensors
