Method for measuring volume of dairy cow mammary tissue

Abstract

The method provides a method for measuring a volume of dairy cow mammary tissue. The method includes the following steps of placing two shooting devices at a plurality of preset positions on two sides of a fence respectively, calibrating the shooting devices, collecting images as original images, acquiring a dairy cow breast image, constructing a three-dimensional description of a breast shape, calculating an upper bound depth and a lower bound depth of a mammary tissue distribution area of each breast area, acquiring three-dimensional coordinates of upper and lower bounds of the mammary tissue distribution area in a normal vector direction of an external three-dimensional point cloud, constituting inside and outside three-dimensional descriptions of the cow mammary tissue distribution area, acquiring the ratio of mammary tissue in an ultrasound image of each breast area, and calculating an actual volume of the mammary tissue of each breast area. According to the method for measuring the volume of the dairy cow mammary tissue, a cow breast three-dimensional model is constructed by means of a computer vision technology, measurement of the appearance assessment index data and volume is performed, internal tissue distribution of organs are analyzed through the ultrasound image, and real-time measurement of a proportional relation of the internal tissue distribution of cow breasts is performed.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for measuring the volume of milk cow mammary gland tissue. Background technique [0002] At present, my country's dairy industry has made great progress in the field of management and production application research, but there is still a certain lag in research in basic fields such as dairy cow breeding, nutrition and lactation, which has become an important factor restricting the efficient, healthy and sustainable development of my country's dairy industry. bottleneck. The mammary glands of dairy cows, as the milk-producing organs of dairy cows, have extremely complex biological characteristics and economic value. Through in-depth research on the changes of mammary glands in a milk production cycle and their relationship with nutrient supply, milk production performance and milk production The relationship between the redevelopment level of glandular tissue dur...

Problems solved by technology

However, this method is not only time-consuming and laborious, it is difficult to promote in production, but also frequent manual measurement will cause stress response to dairy cows, which will have a great impact on production

What is even more deficient is that there is no quantitative analysis and development process tracking of the external volume and shape characteristics of the breast, as well as the distribution and proportion relationship of relevant internal tissues.

[0004] On the other hand, there are few studies on the development of mammary gland tissue, and most of the methods used are to slaughter experimental animals at different developmental stages for data collection

Although the method of slaughtering and dissection can accurately study the development of mammary gland tissue in a certain development period from the microscopic level of cells, it cannot realize the whole process of tracking the physiological development of mammary glands in the same individual, and because the subsequent production performance data cannot be obtained.

Therefore, it is impossible to study the relationship between the developmental law of dairy cow mammary gland tissue, feeding program and milk production performance.
