Problems solved by technology

However, at present, pig individual identification is mostly completed by RFID pig ear tag recognition or pig face recognition based on images. The former is costly and the operation process is complicated. The ear tags are often lost, and the latter will decrease the recognition rate with the growth of the pigs, which will lead to inaccurate monitoring of the growth traits of the pigs

Embodiment 1

[0055] This embodiment discloses a group pig individual recognition system based on spraying characters and image recognition. Based on character spraying and image recognition, the system realizes individual numbering of pigs in a non-contact manner, which can reduce the stress response of pigs caused by manual intervention and reduce the Risk of disease in pigs.

[0056] Such as Figures 1 to 5 As shown in , the pig group individual identification system in this embodiment includes a central processing system, a first spraying identification control mechanism set at the entrance of the pig growth house 1, and a second image acquisition device set above the group pig activity area 7 in the pig growth house 8. And the second spraying identification control mechanism set at the corresponding position of the feed tank 10 of the pig growing house.

[0057] There is an entrance channel for pigs to pass through at the entrance of the pig growth house. The entrance channel can acco...

Embodiment 2

[0082] This embodiment discloses a group pig individual recognition method based on sprayed characters and image recognition. The method is realized based on the group pig individual recognition device in Example 1. The following specific execution steps can be carried out through the group pig individual recognition in Example 1. The central processing system of the device is realized. The central processing system can refer to devices in smart devices such as computers and servers, or it can be directly an independent control board. The specific execution steps include:

[0083] S101. Control the closed state of the entrance passage of the pig growth house, so that the pigs are positioned in the entrance passage; in this embodiment, the outer door of the entrance passage can be controlled by the first door opening and closing control device and the second door opening and closing control device and the opening and closing state of the inner door, after the pigs enter the entr...

Embodiment 3

[0095] This embodiment discloses a storage medium, which stores a program. When the program is executed by a processor, the individual identification method for group pigs described in Embodiment 2 is realized, as follows:

[0096] Control the closed state of the entrance passage of the pig growth house so that the pigs are positioned in the entrance passage;

[0097] Controlling the first image acquisition device above the entrance passage to collect the initial backfat image of the pigs in the entrance passage, and acquiring the initial backfat image of the pigs collected by the first image acquisition device;

[0098] Determine the position of the pig's backfat according to the acquired pig's initial backfat image, and control the first character spraying device above the entrance channel to move to the corresponding position, and carry out character spraying on the pig's backfat;

[0099] Control the first image collection device to collect the pig backfat image of sprayed...

Abstract

The invention discloses a herd pig individual recognition system and method based on spraying character and image recognition. The herd pig individual recognition system comprises a central processing system, a first spraying recognition control mechanism and second image acquisition equipment; The first spraying identification control mechanism is arranged on a closable entrance channel at the entrance of the pig growth house and comprises a first character spraying device and first image acquisition equipment; the second image acquisition equipment is arranged above the pig group activity area in the pig growth house; and the first image acquisition equipment, the first character spraying device and the second image acquisition equipment are respectively connected with the central processing system and are controlled by the central processing system to work. According to the method, herd pig group individual identification can be completed under the non-contact condition, the pig stress response caused by manual intervention can be reduced, and the risk that the pigs are infected with diseases can be reduced.

Description

technical field [0001] The invention belongs to the technical field of intelligent animal husbandry, and in particular relates to a group pig individual recognition system and method based on sprayed characters and image recognition. Background technique [0002] In the process of intelligent group pig breeding and scientific research, the phenotypic parameters of pigs are important indicators to describe the growth performance and feeding behavior of pigs. Growth traits include weight change, backfat thickness, eye muscle area, feed-to-weight ratio, etc. . At this stage, the growth traits parameters are mostly completed by manual measurement. However, manual transitional intervention in the process of group pig breeding and scientific research will cause stress response of pigs and increase the risk of infection of diseases, and the growth traits parameters of all individual pigs in the group pigs cannot be manually measured. Carry out full monitoring and acquisition. In ...
