Automatic livestock and poultry foot parameter measuring method based on machine vision

Abstract

The invention discloses a method for automatically measuring livestock and poultry foot parameters based on machine vision. The method comprises the following steps: S1, collecting pictures containing livestock and poultry feet; s2, segmenting the collected livestock and poultry foot picture; s3, extracting livestock and poultry foot skeleton information from the segmented livestock and poultry foot picture; s4, searching cross points and end points by using the livestock and poultry foot skeleton information, wherein the end points comprise a livestock and poultry foot diameter part upper end point and a livestock and poultry foot diameter part lower end point; s5, determining a positioning point according to the cross point and the end point, and calculating the animal foot diameter length in the image sense according to the positioning point; and S6, calculating the real livestock and poultry foot diameter length and the diameter circumference according to the livestock and poultry foot diameter length in the image meaning. Compared with the traditional manual measurement recording complexity and low efficiency, the livestock and poultry foot parameter automatic measurement method based on machine vision in the livestock and poultry farm provided by the invention has the advantages that the diameter length and diameter circumference of a chicken can be automatically measured through machine vision, the workload of people is reduced, and the visual fatigue of people is relieved.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry intelligent breeding, in particular to a machine vision-based automatic measurement method for livestock and poultry foot parameters. Background technique [0002] The body size and shape of livestock and poultry feet can largely affect the quality of livestock and poultry meat. For example, the body size and shape of chickens are of great significance to the selection of high-quality broilers. Farms need to regularly check the diameter length and diameter information of chickens and record and observe them. The diameter length (commonly known as the length of chicken feet) refers to the diameter of chicken feet The straight-line distance from the upper joint to the center of the palm, specifically the straight-line distance from the upper joint to the third and fourth fingers at the diameter. Diameter circumference refers to the circumference of the middle part of the chicken foot ...
