Animal motion behavior discrimination method and device based on temporal correlation analysis

Abstract

The invention relates to the technical field of motion behavior recognition, in particular to an animal motion behavior discrimination method and a device based on time series correlation analysis. The method comprises obtaining the known continuous motion state of the animal, the corresponding three-axis acceleration information and the continuous three-axis acceleration information to be discriminated; converting three-axis acceleration information into three-dimensional data in natural coordinate system, forming training data with three-axis acceleration information of known motion state and corresponding three-dimensional data, forming test data with three-axis acceleration information to be discriminated and corresponding three-dimensional data; according to the temporal correlation between the movement behavior states and the iterative regression tree model trained by the training data, judging the movement behavior states of the test data. By combining with the temporality of behavior state, the method makes up for the shortcomings of iterative decision tree in the processing of highly correlated data, and further improves the accuracy of behavior discrimination.

Description

technical field [0001] The invention relates to the technical field of motion behavior recognition, in particular to a method and device for animal motion behavior discrimination based on temporal correlation analysis. Background technique [0002] Dairy cow behavior is an important indicator of cow health and welfare, and accurate judgment of cow behavior is an important research content of modern animal husbandry. The existing dairy cow behavior discrimination collects a large amount of data, and the correlation is relatively heavy. The cow behavior discrimination analysis is mostly done by establishing a model. The iterative decision tree model is composed of multiple decision trees, and the conclusions of all the trees are accumulated to make the final answer. , it was considered to be a model with strong generalization ability together with the support vector machine model when it was proposed. Using the iterative decision tree model can make feasible and effective res...
