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...
