3D scanning system for dynamic identification of cow body shape

Abstract

The invention belongs to the technical field of detection devices, relates to a 3D scanning system for dynamical conformation assessment of dairy cows and solves problems of failure in dynamic scanning, low precision, low detection efficiency and the like of an existing device. The 3D scanning system comprises an arch detection device which is provided with at least one detection unit, the top of the arch detection device is connected with a fixing platform through a rotating motor, the fixing platform is erected on a fixing frame above the arch detection device, and a server and an automatic dairy cow identification device is arranged on the fixing frame. The server is connected with a rotating motor and a detection unit, the rotating motor is driven through the server to control the arch detection device to move, the automatic dairy cow identification device acquires data in a radio-frequency card on a dairy cow body, and dairy cow conformation pictures and dairy cow identification data collected by the detection unit are transmitted to a management terminal through the server. The 3D scanning system provides reference data for feeding, election and assortative mating of the dairy cows to improve dairy cow management level and production efficiency and has a guiding significance.

Description

technical field [0001] The invention relates to a 3D scanning system for dynamically identifying the body shape of dairy cows, and belongs to the technical field of detection devices. Background technique [0002] For large-scale dairy farming enterprises, dairy cow body condition score (BCS), linear identification of dairy cow body shape, and measurement of body size (body height, chest circumference) play an important role in guiding the optimization of dairy cow breeding strategies, selection of breeds, and improvement of cattle group size. However, this aspect requires a large amount of work and requires trained professional technicians and strict management to implement it. Therefore, only a small number of large-scale dairy farming enterprises in China carry out this aspect of work. [0003] Chinese patent 2016102178648 discloses a dairy cow body condition automatic scoring method and device, which provides an automatic dairy cow body condition scoring device. The came...

Problems solved by technology

[0003] Chinese patent 2016102178648 discloses a dairy cow body condition automatic scoring method and device, which provides an automatic dairy cow body condition scoring device. The camera is installed on the upper part of the dairy cow passage for image collection. Both the scoring device and the collection device are static devices. It is carried out, the accuracy of the captured image is poor, and the location limitation is too poor

[0005] Therefore, the above two patents have limitations in identifying the body shape of dairy cows, and cannot dynamically scan the body shape of dairy cows, and there are problems such as poor precision and low detection efficiency.
