Depth image-based broiler growth model fitting method and apparatus

Abstract

The invention relates to a depth image-based broiler growth model fitting method and apparatus. The method comprises the steps of obtaining a depth image of a broiler sample; segmenting a broiler in the depth image based on a preset image segmentation method; performing one-dimensional feature parameter, two-dimensional feature parameter and three-dimensional feature parameter extraction according to the segmented depth image, performing quantification processing, and building a body weight estimation model of the broiler by adopting various preset regression models; and performing fitting according to the body weight estimation model and various typical nonlinear growth curves so as to obtain a curve model which can represent broiler growth and development to the best. According to the method and the apparatus, the body weight of the broiler is subjected to informationized decision-making by adopting the depth image and the growth curve model; feature index parameters capable of effectively expressing the body weight of the broiler are extracted by utilizing information contained in the depth image; and the growth curve fitting of the broiler is realized on the whole in a mode of carrying out quantitative calculation and variable accurate fitting successively, so that a growth and development law of the broiler can be predicted conveniently.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry breeding management, in particular to a method and device for fitting a broiler growth model based on a depth image. Background technique [0002] The growth curve model is used to describe the change rule of animal body weight or the increase of animal body weight at a certain age. The establishment and analysis of growth and development models is one of the main methods to study the growth and development of livestock and poultry. At present, the classical nonlinear growth curve model is commonly used to fit the growth curve. By fitting and analyzing the growth curve of livestock and poultry, it can not only predict the growth law of poultry, but also guide the feeding management and improve the breeding effect. [0003] At present, the growth curve model fitting method of broiler chickens mainly uses electronic scales to directly weigh broilers, and then performs fitting and com...
