Embodiment approach

[0023] The implementation mode includes the following steps:

[0024] (1) Utilize the camera image wireless acquisition equipment to collect the first nail 1, the second nail 2 double nails and the two-dimension code 3 with ID to identify the dynamic pig group image of the ear tag, and send it to the remote calculation processing computer through the Internet. Intelligent algorithm for processing.

[0025] (2) Combining the random theory with the edge detection Candy algorithm to establish a new random Candy edge operator, the new operator can consider the randomness caused by the acquisition error of the equipment itself and the distortion of the pig's body during the image acquisition process. Use this operator to extract individual images of pigs with complete standard and unified ear tags in the image.

[0026] (3) Use deep learning RCNN to identify the whole pig and its main external organs: pig head and pig ears. Keep the image as an image of a pig with a full body or ...

Abstract

The invention discloses a method for dynamically measuring the weight of a swinery and analyzing the growth trend of the swinery, and relates to a method for dynamically feeding the swinery. The method includes: using a camera image wireless acquisition device to acquire a dynamic swinery image with identification ear tags on two nails, and transmitting the dynamic swinery image to a remote operation processing computer through the Internet; extracting a complete image of the pig with the complete ear tag in the image; using a deep learning RCNN to identify the whole pig and main appearance organs: a pig head and a pig ear; identifying an ear tag in the image through an intelligent algorithm to obtain an individual identification id; determining boundaries of the three identification targets by using an edge detection algorithm, subtracting the minimum ordinate from the maximum ordinate according to edge detection to perform the same processing on theabscissa to determine length and width feature sizes, and comparing the length and width feature sizes with the ear tag size to obtain a real size; according to the real size, reversely deducing the real weight by an empirical formula. The method is suitable for obtaining weight identification of pigs in group movement, giving a growth trend curve of each pig, digitally guiding fattening of a breeding factory, and improving benefits of the breeding factory.

Description

technical field [0001] The invention relates to a method for dynamic management and analysis of pig groups, in particular to a method for dynamically measuring the weight of pig groups and analyzing their growth and development trends. Background technique [0002] At present, there are many problems in the weight measurement of dynamic pig groups in farms. For example, for pig weight measurement, the usual method is to measure the weight of pigs, which will consume a lot of labor, which is very expensive for the farm Sometimes, stress problems in pigs can also arise. Therefore, for farms, there is an urgent need for a method for measuring the weight of dynamic pig groups and analyzing the growth and development of pig groups, quickly and accurately managing the group of pigs, and avoiding the purchase, installation and use of pig group equipment by users. There was an inaccuracy problem. Contents of the invention [0003] The purpose of the present invention is to provi...
