Device and method for assisting in estimating uniformity of chicken flocks

Abstract

The invention discloses a device and a method for assisting in estimating the uniformity of a chicken flock. The method comprises the following steps: acquiring depth images of a single broiler chicken required for establishing a uniformity prediction model and weight values corresponding to the depth images for multiple times by using an early-stage data acquisition device; performing image preprocessing on the depth image of the single broiler chicken; establishing a uniformity prediction model; acquiring a depth image of the chicken flock by using a later-stage data acquisition device; performing image segmentation on the depth image of the chicken flock to obtain each segmented image; inputting each segmented image into a uniformity prediction model to predict the weight value of each broiler corresponding to each segmented image, and calculating the overall uniformity of the chicken flock; and sending the predicted weight value of each broiler chicken and the overall uniformity of the chicken flock to a client. By means of the method, chicken flock uniformity information can be quickly, accurately and efficiently obtained, so that the problems of low manual operation efficiency and high labor intensity are solved, the breeding cost is reduced, the stimulation influence on the chicken flock is avoided, and the animal welfare is improved.

Description

technical field [0001] The invention relates to a device and method for assisting in estimating the uniformity of chicken flocks. Background technique [0002] Flock uniformity includes three aspects: body uniformity, body weight uniformity, and sexual maturity uniformity. Body uniformity is basically fixed in the early brooding period, which determines the uniformity of body weight. Body weight uniformity can be improved by grouping, group adjustment, and feed regulation, which in turn determines the consistency of sexual maturity, that is, the uniformity of sexual maturity. [0003] Uniformity is often used as a key indicator for judging the production performance and economic benefits of chicken flocks. Farming enterprises judge the health status, nutrition and welfare level of chicken flocks according to the uniformity of the flocks, and then take adjustments in feeding and management measures. Therefore, continuous, accurate and efficient detection of chicken flock un...

Problems solved by technology

[0004] The traditional method of estimating the uniformity of chicken flocks is mainly to manually grab broilers, use electronic scales to measure body weight, read data, record data, count data and calculate uniformity. Although measuring instruments can measure the weight of chickens more accurately, but Due to the frequent struggle of broilers during the weighing process, the weighing platform shakes obviously, and the result will deviate from the actual weight due to the accumulation of dirt

At the same time, when measuring the weight of the broiler chicken, it is often necessary to contact the broiler chicken, which will increase the stress response of the broiler chicken, make the broiler chicken in poor condition in the subsequent feeding environment, and in severe cases, the broiler chicken will be in a bad mood and cause its death. Conducive to the welfare of broiler chickens

Not only that, measuring the weight of broilers requires manual picking of broilers from the chicken coop or cage one by one, which consumes manpower and material resources, leading to a straight rise in breeding costs, and the uniformity of the flock cannot be calculated frequently, making it impossible for farmers to know the growth status of the flock in a timely manner
