The invention discloses a non-contact pig
living body carcass character determination method and
system, and the method comprises the steps: obtaining the multi-
modal characteristic data of a pig through a non-
contact sensor array, and the sources of the multi-
modal characteristic data at least comprise the visible light image, three-dimensional depth information and temperature distribution of the surface of the pig; performing
feature extraction and collaborative fusion on the multi-
modal data to generate a comprehensive
feature vector; and based on the comprehensive
feature vector, evaluating and classifying the
body condition of the pig through an intelligent multi-level classification
algorithm. Complete non-contact automatic detection is achieved, an operator only needs to start the
system and set detection parameters, direct contact with a pig is not needed, and the
safety risk of the operator and the stress reaction of the pig are avoided. Compared with ultrasonic operation needing
professional skills, the
system is easy to operate, and common breeders can use the system skillfully through simple training. The system has the functions of automatic calibration, fault diagnosis and remote monitoring, and the maintenance cost and the technical threshold are greatly reduced.
