Problems solved by technology

[0005] One of the important indicators to detect the health status of pigs is to observe and analyze the pig's face. At present, most of the pigs are directly observed and analyzed manually. There are certain errors, and the

Embodiment 1

[0034] Example 1, such as Figure 1-8As shown, a natural state pig face image acquisition system includes a base plate 1 and a controller 25, the bottom of the base plate 1 is provided with a pressure sensor, and the left and right ends of the upper surface of the base plate 1 are provided with two horizontally penetrating gutters 10; The right end of the bottom plate 1 is fixed with a vertical plate 2, and the lower part of the vertical plate 2 is provided with a strip groove 17; the front and rear sides of the vertical plate 2 are respectively provided with a limit column 8, and the inner side of the limit column 8 is provided with two parallel chutes 13. A ground wheel mechanism is arranged on the left and right sides of the lower end of the limit column 8. The ground wheel mechanism includes a ground wheel 12, a rotating shaft 11, and a wheel barrel 9. The upper end surface of the wheel barrel 9 is fixedly connected with the lower end of the limit column 8. The ground wheel...

Embodiment 2

[0039] Embodiment 2, the present invention also provides a natural state pig face image acquisition method, comprising:

[0040] S1: Add feed to the trough, drive the pig into the device, the pig is tempted by the feed to eat, the pressure sensor senses the weight of the pig, and the pressure sensor transmits the signal to the controller;

[0041] S2: The controller controls the motor to rotate after receiving the signal transmitted by the pressure sensor, and the motor drives the rotating rod to rotate. When the rotating rod rotates, because the rotating rod and the two connecting rods rotate in the opposite direction, the two connecting rods are driven away from each other. Then drive the hinge mechanism to unfold;

[0042] S3: When the hinge mechanism is unfolded, the adjacent poles are far away, and the sliding rod at the end of the pole moves to both ends of the chute on the limit bar, driving the two limit bars to move inward, and the ground wheel mechanism moves inward ...

Abstract

The invention particularly relates to a natural-state pig face image acquisition method and system. The method comprises the steps that pigs are driven into a device, limiting adjustment is conductedon the pigs through a limiting fence, the height of a feeding trough is adjusted, the heads of the pigs in the feeding process are lifted, and the faces of the pigs are shot through a camera; the images are stored, so that subsequent comparative analysis on the health state of the pig is facilitated; according to the invention, manual work can be replaced, and image acquisition is carried out on atarget object face through the camera device; according to the system, manual observation on the face of the pig is reduced, and the image is stored, so that subsequent pig health forms can be compared conveniently, and the state of the pig can be known immediately; and corresponding countermeasures are taken, so that the defects and technical limitations of manual observation can be well overcome and solved technically.

Description

technical field [0001] The invention belongs to the technical field of pig breeding, in particular to a method and system for acquiring pig face images in a natural state. Background technique [0002] At present, scholars at home and abroad have conducted a large number of studies based on intelligent mechanical monitoring of pig status. This is also in line with the requirements of factory and large-scale pig raising models. With the development of video technology, animal behavior recognition technology based on image processing technology and the technology of using multi-sensors to monitor animal behavior are gradually mature. Kaufman et al. used multi-sensors to monitor the rumination behavior of dairy cows every day. Through data collection and analysis, it was concluded that the risk of subclinical ketosis after production can be judged by monitoring the rumination time of dairy cows. Chelotti et al. judged the feeding behavior of dairy cows by monitoring the sound...
