Embodiment Construction

[0029] The present invention is described in further detail below in conjunction with accompanying drawing:

[0030] From the perspective of bionics, the present invention designs a set of multi-moving target large-scale search and precise positioning device by using the visual characteristics of animals and birds in the relationship between predators and birds. It has the characteristics of wide field of vision for prey animals and developed binocular vision of predator animals, and can search and locate multiple moving targets in a large range. In the process of searching and positioning, it has the "double concave" feature of the bird, and realizes the function switching of multiple cameras. On the basis of imitating the visual characteristics of birds, it has expanded its functions and has a larger monitoring range.

[0031] The invention consists of a horizontally installed circular base, four identical 2-degree-of-freedom monocular mechanisms evenly distributed along th...

Abstract

The invention discloses a device and method for searching for and positioning multiple moving objects on the basis of bird visual features. In the perspective of bionics, bionic design is carried out by combining visual features of animals in the prey relation and double-concave structure features of birds. The device is composed of a horizontally installed round base, four identical two-degree-of-freedom monocular mechanisms evenly distributed along a circle, a fixed camera part installed in the middle of the base, a corresponding computer, a circuit part and the like. The device integrates the characteristics that preyed animals are wide in vision and vision of the two eyes of prey animals is advanced, can achieve quick search and accurate positioning of the moving objects in the panoramic range at the same time, and is applicable to application and popularization of the visual surveillance field in engineering practices.

Description

【Technical field】 [0001] The invention belongs to the field of bionic design, and relates to a multi-moving target search and positioning device and method based on bird visual features. 【Background technique】 [0002] The search and tracking of moving targets is a hotspot in the field of machine vision, and it is also widely used in practice. The key to the problem is to ensure the speed and accuracy of large-scale search and positioning. There are mainly two types of existing technical solutions: one is to use monocular or binocular vision to identify, track and locate the target. At present, this scheme can realize accurate identification and positioning of moving targets, but this method cannot guarantee large-scale search and precise positioning of multiple targets at the same time; the second is to install enough cameras in the area that needs to be searched , to make the region searchable. Although this method solves the above problems to a certain extent, the cost...
