Embodiment Construction

[0061] The invention includes a lower computer hardware design and a slide rail control program module, a server-side software interface program, a binocular vision weighing program based on Bumblebee-3, and a drinking behavior recognition program based on a traincascade classifier.

[0062] The hardware design of the lower computer and the slide rail control module can manually control the start and stop of the CCM-W60-35 slide rail, and the PLC200 224XP can also receive the control signal from the upper computer to remotely control the start and stop of the slide rail; the server The software interface on the terminal can send slide rail control signals to the client, can receive the actual weight information transmitted to the host computer through GPRSDTU when the pigs are eating, and can predict the weight information of the pigs; it can read the photos taken when the pigs reach the drinking area The local photos are input into the traincascade classifier to identify a...

Abstract

The invention discloses a pig weight measurement and water drinking behavior recognition system and a method based on binocular vision. The method comprises the steps of shooting a picture of the backof the pig and obtaining the body height of the pig; defining the position of the pig during feeding, extracting the contour of the pig, setting the pixel point of the pig back image to be 0 by adopting binarization processing, and calculating the number; and comparing the calculated number of the black pixel points with the previously verified number of the pixel points of the 10CM * 10CM blacksquare at each height, and performing fitting operation on the actual back area of the pig, the body height of the pig and the actual weight of the pig to obtain the estimated weight of the pig; monitoring drinking water; when the white pixel points in the water drinking area exceed 50%, preliminarily judging the water drinking behavior; tracking the mass center of the pig; when the moving distance of the center of mass does not exceed the threshold value, capturing 20 * 20 CM pictures around the water fountain in the tenth picture and inputting into a traincascade classifier, comparing the pictures in the water drinking area to judge the content of the pictures, and if the content of the pictures is the head of the pig, finally judging that the pig drinks water.

Description

technical field [0001] The invention relates to the field of new digital agricultural management systems, in particular to use binocular depth camera technology to estimate the weight information of pigs and make accurate judgments on the drinking behavior of pigs. Background technique [0002] The overall scale of my country's pig industry has long been at the forefront of the world, and the pig industry has played an important role in my country's economic development. Since 2012, the number of pigs in stock at the end of the year and the number of slaughtered pigs in my country have shown an obvious downward trend. The main reason for the low efficiency of the pig breeding industry at this stage is that the epidemic situation was not handled in time, resulting in high mortality and unqualified rates. Last year Since then, "African swine fever" has ravaged our country and severely damaged my country's pig breeding industry. At present, the prevention and treatment of pig d...
