Prediction method and the apparatus for onset time of sow farrowing by image analysis

摘要

A method of predicting a delivery time of a mother pig using image analysis according to an aspect of the present invention includes: collecting a delivery image data for each class of behavior patterns according to behavior characteristics of a pregnant mother pig by a delivery time prediction device; The delivery time prediction device normalizes the behavior pattern for each class of pregnant mother pigs to the predetermined coordinates with respect to the learning image data according to reference coordinates, and as learning processing data capable of recognizing the characteristics of the behavior pattern in the CNN recognition model. Processing to extract; A step in which the delivery time prediction device accumulates and learns processing data for learning for each class behavior pattern by applying a CNN recognition model; Storing the learned data in the behavior pattern database by the delivery time prediction device; Collecting the image data for recognition of the mother pig for recognition by the delivery time prediction device; The delivery time prediction device normalizes the recognition image data to a certain standard according to reference coordinates, and applies the CNN recognition model to recognize the behavior pattern of a mother pig for the recognition image data, and patterns for each class Classifying as one of; An analysis step of analyzing the expression pattern by time zone or the occurrence frequency and change trend by time zone for the classified behavior pattern; And a delivery prediction time notification step for determining the delivery prediction time point for the recognition mother pig from the analysis step and outputting the notification from 24 hours before.
