Automatic cow body condition scoring method and scoring device

Abstract

The invention provides an automatic cow body condition scoring method. The method comprises steps that the information of a radio frequency label on an ear of a cow is acquired through the reading-writing equipment when the cow passes by, and the information of the radio frequency label comprises the identification information of the cow; the acquired information of the radio frequency label is sent by the reading-writing equipment to a processing platform; after the information of the radio frequency label sent by the reading-writing equipment is received by the processing platform, a control instruction is sent to a scanner; after the control instruction is received by the scanner, 3D images of a back portion of the cow are acquired, and the 3D images are sent to the processing platform; the cow body condition is scored through a preset algorithm by the processing platform according to the 3D images, full-automatic accurate cow body condition scoring is realized, problems of time and labor consuming and strong subjective property existing in a manual field observation touch scoring method in the prior art are solved, and the method is suitable for automatic cow body condition scoring of farming enterprises having high throughput.

Description

technical field [0001] The invention belongs to the field of agricultural technology, in particular to a method and device for automatically scoring the body condition of dairy cows. Background technique [0002] Optimizing the genetic traits of dairy cows and improving the yield and quality of milk are the most important aspects of milk production. However, in the process of dairy cow breeding, too thin or overweight cows often appear. If these cows are not monitored in time and corresponding measures are taken These measures will affect the milk production, productivity, health and longevity of dairy cows. Dairy cow body condition scoring (BCS) is considered an important management tool, which can be used to estimate the energy reserve status of dairy cows and their fatness and leanness. Thus reflecting whether the dairy cows meet the requirements for a period of time, so as to adjust the D feeding method. Typically, BCS is assessed on a 5-point scale, with 1 being an ov...

However, the infrared thermal imaging technology used in this method is a temperature-sensitive imaging method, which is greatly affected by the external environment temperature and is not a robust method.

Furthermore, as a three-dimensional living animal, cows use two-dimensional images for information acquisition, and cannot extract and describe features from a three-dimensional perspective
