AI Technical Summary

Technical Problem

Existing Real-Time Location Systems (RTLS) for animal tracking in farms suffer from low precision and intermittent monitoring due to radio signal periodicity, leading to undetected animal movements and increased costs with large areas.

Method used

A dual positioning system combining radio-based and camera-based sub-systems, where radio signals are used for initial identification and cameras provide continuous monitoring, allowing precise tracking and behavior analysis.

Benefits of technology

Enables reliable, continuous animal tracking and early detection of deviating behaviors or health issues, reducing costs and enhancing milk yield by minimizing animal suffering and losses.

Abstract

A system (100) for tracking movements of a plurality of animals (101, 102) at a farm (200). The system comprises a controller (130), a first positioning sub-system (10), and a second positioning sub-system (20). The first positioning sub-system comprises a plurality of identity transmitting units (110, 112) transmitting signals with identities, and signal receivers (120a, 120b, 120c) determining signal-related parameters to create a first animal trajectory (150a). The second positioning sub-system (20) comprises a visual sensor arrangement (400) for capturing images in a visual zone (220). The controller obtains images of the animal to compose a second animal trajectory (150b). The controller then matches the trajectories (150a, 150b) in time, room, and direction, associating the animal of the second trajectory with the identity of the first trajectory.
