Method for estimating body size and weight of yak and corresponding portable computer device

Abstract

The invention provides a method of estimating the body size of a yak, based on 3D vision. The method of estimating the body size of a yak, based on 3D vision includes the steps: acquiring the side images of a yak by means of image acquisition equipment; extracting the foreground images from the side images; identifying the key points of the yak body from the extracted foreground images; and by means of the identified key points of the yak body, automatically extracting the body size information of the yak. The invention also provides a method of estimating the weight of a yak, based on 3D vision. The method of estimating the weight of a yak, based on 3D vision includes the steps: including the method of performing the method of estimating the body size of a yak; and taking the extracted body size information of the yak as input, and utilizing a yak weight estimation model to predict the weight value of the yak. Alternatively, the invention furthermore provides a method of estimating the weight of a yak, based on 3D vision. The method of estimating the weight of a yak, based on 3D vision includes the steps: acquiring the side images of a yak by means of image acquisition equipment; extracting the foreground images from the side images; and directly predicting the weight value from the foreground images, by means of a convolution neural network. The invention also provides a corresponding portable computer device.

Description

technical field [0001] The present invention generally relates to a method for estimating the body size and weight of a yak, in particular to a method for estimating the body size and weight of a yak by using a neural network. The invention also relates to a corresponding portable computer device for carrying out the method. Background technique [0002] With the development of science and technology and the advent of the era of big data, the informatization and intelligence of animal husbandry is the top priority to promote the rapid and healthy development of animal husbandry in my country. With the help of intelligent and automated data collection and computer-aided analysis, the production scale of animal husbandry can be improved, labor costs can be reduced, and production efficiency can be enhanced. [0003] For yaks in the animal husbandry industry, according to statistics, there are about 22 million yaks in the world, and China accounts for more than 90% of them, an...

Problems solved by technology

However, there are still some deficiencies in the existing work. The core shortcoming is that the existing work is basically the measurement of body size in a restricted space, that is, it is necessary to stabilize the living animal in a specific space, a specific location and a specific equipment. This method is conducive to obtaining a large amount of data in batches, and has strong versatility, but the measuring device is often complex in structure and high in cost, and is limited to a fixed position of the device, cannot be moved, and has a certain stress on livestock
