Horse body measurement system and data correction method based on 3D

Abstract

The invention discloses a horse body measurement system and a data correction method based on 3D. Horse body measurement data are important basis for measuring growth development and scientific feeding and breeding of horses. Different from a manual measurement method, the horse body measurement system based on machine vision has obvious advantages in the aspects of measurement safety and high efficiency. Based on skeleton design of CINEMA 4D software and according to a modeling idea of a linear regression equation, data collection of body heights, body lengths, chest circumferences and cannoncircumferences of Yanqi horses is finished at first; then corresponding body measurement data correction methods are respectively discussed under the two situations that horse body standing posturesare not standard; finally, Matlab software is utilized to initially finish simulation testing of the horse body measurement system. Simulation results show that the machine vision measurement method based on 3D images has measurement basis for collecting body measurement data when the horst standing postures are not standard, and utilizing a linear regression theory to predict the horse body measurement data has reference significance in developing related body measurement systems.

Description

technical field [0001] The invention relates to the field of animal body size, in particular to a 3D-based horse body size measurement system and a data correction method. Background technique [0002] Xinjiang is a large traditional horse breeding area in my country. There are abundant horse breed resources. According to the national breed resource survey, there are currently four local breeds in Xinjiang, including the Kazakh horse, the Balikun horse, the Yanqi horse, and the Kirgiz horse. The two cultivated varieties of Wuma are the first in all provinces, municipalities and autonomous regions in the country. Horse breed registration means that a special registration agency classifies horse breeds based on information such as pedigree, body size, appearance, and production performance. Therefore, body size measurement technology has become indispensable in identifying horse breeds in Xinjiang and promoting the process of improving horse breeds. Technology. [0003] At pr...

Problems solved by technology

Measure the body shape of animals and establish a structured special device. The advantage is that it is convenient for image acquisition and calibration, and realizes linear measurement of the reference points of interest.

[0004] To sum up, the current automatic index acquisition method is mainly based on two-dimensional images and structured facilities to limit the pose of animals. The requirements for animal pose or environmental lighting and background are relatively strict, which is difficult to meet in actual production. Moreover, 2D machine vision technology itself cannot obtain indicators related to the shape of the animal's body surface
