Abstract
The present invention relates to the field of artificial intelligence technology, and proposes a poultry health assessment method and system based on the statistical characteristics of group exercise, which includes the following steps: acquiring poultry data from foot rings with three-axis sensors worn by poultry, and analyzing the acquired data Perform preprocessing to obtain poultry exercise data; perform abnormal data detection and correction on the poultry exercise data to obtain the corrected poultry exercise data; according to the corrected poultry exercise data, perform poultry exercise data of the same individual and group in different time periods Statistics and data distribution, and perform individual and group scores on poultry according to statistics and data distribution results of poultry exercise data; combine poultry exercise data, individual score results and group score results to evaluate poultry health status, and obtain poultry health assessment results. The invention can effectively improve the poultry health detection precision and accuracy rate, and can intuitively reflect the poultry health status at the same time.
Description
A method and system for poultry health assessment based on statistical characteristics of group exercise technical field The present invention relates to artificial intelligence technical field, more specifically, relate to a kind of statistical feature based on group motion Poultry health assessment methods and systems. Background technique [0002] With the continuous improvement of people's living standards, people's demand for various types of poultry is also increasing. in scale During the breeding of larger poultry (chickens, ducks and geese), the weaker individuals are affected by sudden accidents, such as snatch and other behaviors. Injuries, or the occurrence of individual fights and injuries are unavoidable, and they should be rescued in time or cleaned up in time to avoid further damage. Losses are very necessary. Therefore, for the reasonable monitoring and transformation of the amount of exercise, a health score for health assessment is obtained It is ...
