Affine Transform registration algorithm-based sheep body measuring method and system

Abstract

An affine Transform registration algorithm-based sheep body measuring method and system is characterized in that a binary image of a standard sheep of determined size is used as a template and is registered to a binary image of a sheep to be measured so as to obtain registration parameters, and calculating is performed according to the registration parameters and the size of the standard sheep so as to obtain the size of the sheep to be measured, namely body length and body width. A flock of sheep can be subjected to non-contact body size measuring in real time, and various discomforts of the sheep caused by manual-contact measuring are avoided; the sheep can be subjected to real-time body size measuring, real-time shooting is performed during image acquiring, and adjustment is performed in time so that accuracy is improved. The method and the system have the advantages that the requirement on reality scenes is low, a feedback result is provided for each sheep during measuring, and measuring efficiency can be improved.

Description

technical field [0001] The present invention relates to a technology in the field of image processing, specifically a method and system for measuring sheep body size based on an affine transformation registration algorithm. special flock). Background technique [0002] Inner Mongolia is the main growing area for sheep, with fresh grass and prairie suitable for sheep. At the same time, with the continuous development of society, people's living standards are constantly improving, and the demand for mutton has increased significantly. Therefore, it is very important to evaluate the growth status of sheep. The body size of sheep is a main parameter for evaluating the growth status of sheep, and it is also an important index in terms of seed selection, meat quality evaluation and feeding management. [0003] The traditional method of measuring the body size of sheep is mainly through direct measurement with walking sticks and measuring tapes. This method of measurement requires...

Problems solved by technology

The installation and operation of the device is complicated, and continuous manual adjustment is required to obtain good images, which makes the operation complicated and inefficient

[0006] Since the body color of the sheep is relatively pure (pure black, pure white, and pure white Sunit black head sheep), and the sheep are herd livestock, the efficiency of manual measurement is too low for a large number of sheep, and it is difficult to design for them due to their large size. sex measuring equipment
