Detection of Low-Weight Pigs using a Top-View Camera

Abstract

Caring weaning pigs is important in the management of a group-housed pig farm. In this study, we propose an automatic method for detecting low-weight pigs in a pigsty. We install a top-view camera in a room of weaning pigs to detect the motion area of each pig from the video obtained. Then, we automatically detect a low-weight pig by comparing the size of each pig. Based on the experimental results, we confirm that the proposed method can automatically detect relatively low-weight pigs without any manual inspection or measurement of actual weight by a farm administrator.
