A method and system for exterminating rodents in grassland based on image and cluster analysis

Abstract

The present invention provides a grassland rodent control method and system based on image and cluster analysis, which determines the point where the maximum absolute value of the pixel difference of a single coordinate point in multiple grassland sub-blocks is located by performing image analysis on the target grassland, Then determine the initial placement point of rat bait, and further determine the final placement point of rat bait based on cluster analysis. The invention realizes the automatic positioning of the mouse bait delivery point by automatically acquiring and analyzing the image, uses the pixel difference analysis of the image to find and locate the vegetation area seriously damaged by the rodent, and effectively distinguishes the rodent active area and the non-active area based on the clustering method. The active area can determine the more accurate placement of mouse bait, which can improve the utilization rate of mouse bait and avoid excessive pollution of grassland vegetation by mouse bait.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method and system for exterminating rodents in grasslands based on image and cluster analysis. Background technique [0002] The large-scale development of domestic animal husbandry is mainly concentrated in the northwest region. Most of the northwest region has a temperate continental climate, with little rain and wind in four seasons, dry climate, long and severe winter, short and cool summer, late spring and early autumn, and low annual precipitation. , from south to north, decreasing from southeast to northwest, with large seasonal and interannual changes, and an average annual temperature of 8.1°C. Therefore, this special geographical location and harsh natural conditions determine the dominant direction of economic development in animal husbandry areas Mainly sheep. Grasslands in Northwest China are mainly divided into four types: dry grassland grass...

Problems solved by technology

[0005] However, there are following defects in the above-mentioned two commonly used rodent control methods. The fixed-point injection of rat poison or mouse trap is usually thrown at a fixed distance interval. In areas with few rodents, there will be excessive rat poison or traps, which will cause secondary pollution to the grassland. Therefore, the method of releasing at fixed distance intervals cannot effectively distinguish rodent active areas from inactive areas, and cannot ensure the protection of rodents.
