On-site counting and weighing method and system for chickens

Abstract

The invention discloses a field counting and weighing method and a system for chicken. A platform composed of a frame, a support rod and a mesh material is built; a CCD camera is fixed above a weighing platform; pressure sensors for measuring the body-weight of chicken are respectively fixed at four corners of the lower part of the ground weighing platform in a farm; when 1-n chicken naturally stand on the weighing platform, and the total change of the measured body-weight of the chicken is smaller than a set threshold, the CCD camera is triggered to obtain an image of a region of the weighing platform; the quantity of the chicken on the weighing platform can be obtained by image treatment; the mean body-weight of the chicken is calculated according to the total body-weight and the quantity of the chicken on the platform. According to the field counting and weighing method and system, the interference caused by human factors in the weighing process is reduced; the effect on the body-weight of the chicken caused by chicken manure is reduced by a weighing platform design grid; the accuracy of the mean body-weight is improved; the poultry weight at different growth stages is obtained by a fixed time interval starting system; whether a problem exists in chicken house management such as feed supply is judged by comparing with a normal weight gain curve; the feeding time can be reflected.

Description

technical field [0001] The invention relates to a weighing method and system, in particular to a method and system for on-site counting and weighing of chickens. Background technique [0002] With the promotion of large-scale farming, chicken has become the most consumed meat product in the world. In actual breeding, body weight is a direct reflection of poultry production and an important indicator to measure the growth and development of poultry. Therefore, by obtaining the weight of poultry at different growth stages and comparing it with the growth curve, you can know the problems in the breeding process, and you can also remind the date of the chicken's slaughter. At the same time, according to the habitat characteristics of birds, perches shaped like slender branches are more suitable for chicken feet to grasp, and perches are also widely used for raising ornamental birds. [0003] At present, the weight of chickens is usually obtained by manual random sampling and w...

Problems solved by technology

[0004] In order to overcome the deficiency of artificial random sampling and weighing in the background technology, the object of the present invention is to provide a method and system for on-site counting and weighing of chickens, which uses computer vision to count the chickens on the weighing platform, and combines the pressure sensor to send back pressure data to obtain accurate average body weight
