Embodiment 2

[0094] The present embodiment is the same as embodiment 1 in other structures except the following features.

[0095] A device for identifying poultry body size, comprising:

[0096] 1. Image acquisition module.

[0097] It is used to obtain the image of the measurement scene through the depth camera, and the image includes a color image and a disparity image.

[0098] Second, the target extraction module.

[0099] Including judgment module and segmentation module, wherein:

[0100] The judging module is used to judge whether the target poultry appears in the image. The judging method is: using the general feature information of the poultry, transforming the color image into the YCbCr space and projecting it on the CbCr plane, and using the statistical ellipse model to segment the poultry feather outline , and then compare it with the nearest object contour detected by the disparity map. If the intersection ratio is greater than the threshold, it is judged as the target pou...

Abstract

The invention discloses a method and a device for identifying a poultry volume scale and a storage medium. The method comprises: obtaining a chicken color map and a disparity map, calculating point cloud information and world coordinates, and calculating the volume scale. According to the method, the image information of the measurement scene is acquired by using the depth camera, the chicken is quickly segmented through an algorithm, an external clamping device is not needed to fix the measured chicken, and the volume body size information of the chicken is simply and effectively extracted byusing the computer vision while the normal activity of the chicken is not influenced. The depth camera is not influenced by the light intensity and has good adaptability to a scene with unstable light rays in a chicken farm, the measurement precision can be well improved through algorithm processing, chicken size and body size information is measured through visual non-contact, measurement is easy and convenient, and healthy growth of chickens is facilitated.

Description

technical field [0001] The invention relates to the field of visual detection research, in particular to a method, device and storage medium for identifying poultry volume and body size. Background technique [0002] According to statistics, by 2025, the world population is expected to exceed 8 billion, and by 2050 it is expected to reach 9.6 billion. This means that more efficient methods of poultry and livestock production are needed to provide an adequate food source. Poultry such as broiler chickens and pork pigs occupy an important position in poultry farming and are one of the main sources of food. It is of great significance to study the law of breeding development and health warning. [0003] The volume and body size information of poultry is an important indicator in the breeding process. The information measurement involves the volume measurement of irregular objects, and there is no specific mathematical formula algorithm. Traditional measurement methods includ...
