A method and a device for pig tracking based on target detection and a particle filtering algorithm

Abstract

The embodiment of the invention discloses a method and a device for tracking pigs based on target detection and a particle filter algorithm, which are used for shooting the pigs in a group raising column to obtain ordered picture frames. Pigs appearing in the picture are detected through a target detection algorithm, the positions of the pigs are predicted through particle filtering, finally, images of the pigs are matched in combination with calculation of the Euclidean distance, the images corresponding to the same pig in the ordered picture frame are marked through the same label, and a target ordered picture frame is obtained. According to the mark in the ordered picture frame; the behavior of any pig in the group breeding fence can be tracked; the pigs do not need to be manually inspected on site by going to a group breeding fence; The behavior of the pigs can be analyzed only through the target ordered picture frame, the efficiency is high, the basis for comprehensively analyzingthe pigs in the group raising column is provided for the pictures taken at all angles of the group raising column, and accurate analysis on the behavior of the pigs is achieved by tracking the pigs.

Description

technical field [0001] The embodiment of the present invention relates to the field of intelligent farming technology, and in particular to a method and device for tracking pigs based on target detection and particle filter algorithm. Background technique [0002] With the application of electronic information technology in the field of breeding, many breeding places use modern breeding equipment to raise pigs in captivity. For example, equipment for monitoring the weight of the pigs, equipment for monitoring the feeding conditions of the pigs, and equipment for automatically supplying food and water to the pigs are set up in the group breeding pens of the pigs. Modern farming equipment greatly reduces labor costs in the breeding process and saves resources. However, there is a lack of tracking and monitoring of pig activities in the existing breeding equipment, and the behavior analysis of pigs often relies on regular manual inspections. Manual inspections cannot perform a...

Problems solved by technology

[0004] The present invention solves the problem that the analysis of the behavior of pigs often relies on regular manual inspection, and only the activities of pigs can be monitored during the period of manual inspection, and the pigs cannot be tracked in real time, resulting in the inability to detect the existence of pigs in time. Problems and the analysis of pig behavior through manual regular inspection is one-sided, the analysis results are inaccurate, and the efficiency is low
