Embodiment 1

[0034] Embodiment 1 is to the growth monitoring of individual pig

[0035] Establish a pig weight prediction model:

[0036] Formula for determining estimated weight: W=a×S b ×H c ,Proceed as follows:

[0037] (1) Use an electronic scale to weigh the pig body to obtain the real body weight, and repeat 12 groups. The weighing results of 12 pigs of a certain breed type are (unit: Kg): 82, 84, 73, 72, 83, 70, 75, 93, 103, 101, 104, 97, 86.

[0038] (2), obtain pig body height and pig body back area according to the method of the present invention, repeat 12 groups. The body height measurement results of 12 pigs of a certain breed type are (unit: cm): 66.5, 64.2, 65.1, 64.7, 67, 62.1, 64.2, 69.4, 70.8, 69.5, 66, 67.7. The measurement result of pig body back area is (unit: cm 2 ): 2382.583, 2406.449, 2048.681, 2078.866, 2367.247, 2039.72, 2093.333, 2603.881, 2829.876, 2917.269, 2866.778, 2692.713.

[0039] (3) Three coefficients a, b, and c of the estimated body weight formu...

Embodiment 2

[0044] Example 2 Growth Monitoring of Group Pigs

[0045] Select a pig group including 5 individual pigs, and number them, followed by No. 1, No. 2, No. 3, No. 4, and No. 5 pigs. Combined with electronic individual identification technology, the individual pigs in the selected pig group are sequentially identified for growth. detection.

[0046] Choose two color 1 / 3-inch CCD cameras with a minimum illumination of 0.02Lux, a resolution of 600 TV lines, combined with a 5mm auto-iris fixed-focus optical lens, and set up the two cameras on the upper part of the pig house at a height of 2.5m from the ground. The distance between the two cameras is 150mm, parallel to each other, and vertically downward. The camera is connected to the computer through a network cable to form a binocular stereo vision detection hardware system. The body heights of No. 1, No. 2, No. 3, No. 4 and No. 5 pigs were successively measured according to the steps of the above-mentioned Example 1 and were (un...

Embodiment 3

[0049] Choose two color 1 / 2-inch CCD cameras with a minimum illumination of 0.02Lux, and a resolution of 600 TV lines. Combined with a 3mm auto-iris fixed-focus optical lens, the two cameras are erected on the upper part of the pig house, 2.5m above the ground. The distance between the two cameras is 100mm, they are parallel to each other, and both are vertically downward. It is connected with a computer through a hub to form a binocular stereo vision detection hardware system.

Abstract

The invention relates to a method for monitoring pig growth by utilizing a binocular vision technology, and the method comprises the following procedures that: a system is established and calibrated; a pig body image is obtained; the pig body image is transferred; the pig body image is processed; the height of the pig body and the area of the pig body back are measured; and the weight of the pig body is pre-estimated. The growth of the pig is monitored though the method of the invention, the stress to the growth of the pig can not be caused, the operation is easy, the labor strength is reduced, the efficiency is high, the real time is good, the realization of the automation and the network transfer are beneficial, and the remote monitoring can be realized.

Description

technical field [0001] The invention belongs to the technical field of application of computer technology in animal husbandry, and relates to a method for monitoring the growth of pigs using binocular vision technology. Background technique [0002] In pig production, parameters such as pig body height, body length, and body width are important indicators to describe the growth status of pigs. Timely monitoring of these growth information of pigs can provide an important basis for production management and business decision-making. In traditional production, the acquisition of these growth parameters is done manually. Body shape parameters such as body height are generally measured manually by a tape measure, while body weight is determined by weighing boxes and scales. These traditional measurement methods not only need a lot of time and labor, but also have low efficiency, and cause stress to breeding pigs and bring great losses to production. Especially in the daily fe...
