arXiv:2606. 14749v1 Announce Type: new Abstract: Precision aquaculture faces a "phenotyping bottleneck" in tracking high-resolution behavioral traits, as conventional methods cannot quantify instantaneous three-dimensional (3D) physical exertion. To address this, we present a high-throughput 3D behavioral phenotyping framework integrating deep learning object detection with binocular stereo vision for real-time monitoring of juvenile tilapia in high-density environments.
The system automates non-contact body length estimation and reconstructs 3D swimming trajectories from absolute spatial coordinates. …
