Laser bird repelling method and system based on three-dimensional information estimation

Abstract

The invention discloses a laser bird repelling method and system based on three-dimensional information estimation, belongs to the technical field of bird repelling, and aims to automatically search bird movement traces, accurately identify bird targets and repel birds in a targeted manner without manual intervention, so that the bird repelling efficiency is improved. A tripod head is arranged ona movable platform, and a binocular camera and a laser device are arranged on the tripod head. The method comprises the steps that a left-eye image and a right-eye image in a set environment are collected; whether there is the bird targets in the left-eye image or not is detected based on Fast R-CNN, and position information of the bird targets in the left-eye image is obtained; position information of the bird targets in the right-eye image is confirmed according to the position information of the bird targets determined in the left-eye image; a parallax value of the bird targets is determined according to the position information of the bird targets in the left-eye image and the position information of the bird targets in the right-eye image, and three-dimensional position information ofthe bird targets is obtained according to the parallax value of the bird targets; and the orientation of the laser device is adjusted according to the three-dimensional position information of the bird targets, and laser is emitted to repel the bird.

Description

technical field [0001] The invention belongs to the technical field of bird repelling, and in particular relates to a laser bird repelling method and system based on three-dimensional information estimation. Background technique [0002] In recent years, the protection of the ecological environment in my country has become more perfect and systematic, and the speed of bird reproduction has increased significantly. The number of birds in many areas has increased significantly, and the range of activities has expanded, resulting in an increase in the frequency of bird damage. The problem of bird damage is extremely regional. The areas where bird damage occurs are mostly areas where birds and animals gather. These places are sparsely populated, densely forested, and often have rivers, fish ponds, reservoirs and other resources nearby. [0003] The traditional way of repelling birds is mainly artificial repelling birds, which has a large workload and high labor costs; Bird repe...

Problems solved by technology

There are many deficiencies in these existing bird repelling methods, such as: need to be equipped with special inspection personnel and vehicles, adopt a shift system, and the cost of manpower and material resources is relatively high; there is a time interval between the start of bird repelling equipment, so full-time coverage cannot be achieved The efficiency of bird repelling is not high; regardless of whether there is a bird situation, the method of regularly starting the bird repelling equipment is not only inefficient, but also wastes resources in vain, but has no effect; the bird repelling records are recorded manually and then input into the system , not even entered into the system, there is no detailed data and video data of bird situation, so it is impossible to provide overall analysis and utilization of bird situation data, and it is impossible to get the accurate law of bird infestation
