Cow shape measuring method and cow shape measuring system based on stereo vision technology

Abstract

The invention relates to a cow shape measuring method and a cow shape measuring system based on a stereo vision technology. The method comprises the following steps: collecting image information of cow samples at different angles, and calculating body size data of the cow samples according to the image information at different angles; acquiring weight data of the cow samples, and building a weight prediction model according to the corresponding relationship between body size data and weight data; calculating body size data of a cow to be measured according to the image information of the cow to be measured at different angles, and inputting the body size data of the cow to be measured into the weight prediction model to estimate the weight data of the cow to be measured. By using the technical scheme provided by the embodiment of the invention, the problem that weight data measured by a weighbridge is inaccurate due to dynamic nature of cows is solved; and the body size data of cows is acquired through image acquisition, so that the problem that an artificial field contact method is time-consuming and labor-consuming, is of strong subjectivity, and causes stress reaction of cows is solved, and full-automatic cow body size data measurement and weight data measurement is realized.

Description

technical field [0001] The invention relates to the technical field of animal husbandry informationization, in particular to a method and system for measuring dairy cow body shape based on stereo vision technology. Background technique [0002] Animal husbandry uses the physiological functions of livestock and poultry and other animals that have been domesticated by humans, or wild animals such as deer, musk deer, fox, mink, otter, quail, etc., through artificial breeding and breeding, so that they can transform plants such as pasture and feed into Animal energy, in order to obtain meat, eggs, milk, wool, cashmere, hides, silk and medicinal materials and other livestock products, is an extremely important link in the material exchange between humans and nature. Animal husbandry is one of the components of agriculture, and it is listed as the two pillars of agricultural production along with planting. [0003] Dairy cows are yellow cattle of dairy breeds. They are excellent ...

AI Technical Summary

Problems solved by technology

At present, most of the dairy cows are measured manually by manual measurement with a tape measure. These methods not only have a large workload, but also may cause large measurement errors due to human factors, which makes the measurement results lack objectivity; Dairy cows cause a stress response that affects the growth of cows

Further, the weight measurement is done by using a weighbridge, placing a weighbridge on the ground of the cow passage, and obtaining the weight of the cow when the cow passes the weighbridge. This method must require the cow to stand completely on the weighbridge and keep still in order to obtain accurate cow weight data, but it is difficult to keep the cows in this state on site, so this method cannot obtain accurate weight data
