Method and system for automatically detecting and marking weak pigs

Abstract

The invention discloses a method and system for automatically detecting and marking weak pigs. The method comprises the following steps: S1, taking pictures of pigs in a specified field and obtaining pig pictures; S2, performing quality screening on the pig pictures through an image quality judgment model to obtain quality-qualified pictures; S3, adopting the target detection model to carry out weak pig identification on the quality-qualified pictures, and outputting an identification result, wherein the identification result comprises an external rectangular frame of a target, a weak pig category label and credibility; S4, screening identification results of various weak pigs calculated by the target detection model according to corresponding threshold values set for the credibility of the identification effects of the various weak pigs, and after the various weak pig identification results lower than the respective threshold values are removed, combining the identification results of which the intersection-union ratio is greater than a certain threshold value in the screened identification results to obtain a combined result; and connecting the two weak pig category labels and the two credibility levels together, and outputting a final recognition result which is the identification result after intersection-parallel comparison operation.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a method and system for automatic detection and marking of weak pigs. Background technique [0002] With the increasing social demand for meat, the related import volume and breeding scale are constantly expanding. For domestic breeders, how to breed efficiently and how to achieve rapid and healthy growth of farmed animals is an important factor in their farming. [0003] In my country, due to the relatively small grassland area, small population base, and the relatively fast growth rate of pigs compared with other animals, pig farming has become the main source of meat in my country. In the process of pig breeding, the survival rate and growth rate of pigs largely determine the efficiency and profitability of farming. However, due to some genetic factors and other reasons, there will be some weak pigs in the herd. Their physical fitness is generally worse than that of other ...

AI Technical Summary

Problems solved by technology

However, the selection of poor pigs in the traditional pure artificial breeding process is very dependent on the experience level of the breeder, and the breeding performance of the same batch of pigs after being raised by different breeders may vary greatly
