Summary
This study introduces a new 3D horse reconstruction method using consumer cameras for precision livestock farming. The technique improves body measurement accuracy and model integrity for better breeding and health management.
Area of Science:
- Livestock Science
- Computer Vision
- Biotechnology
Background:
- Precision livestock farming (PLF) requires accurate 3D horse models for breeding and health monitoring.
- Existing 3D reconstruction methods face challenges with equine body shape variations and environmental noise, limiting practical application.
Purpose of the Study:
- To develop an image-to-3D pipeline for high-fidelity 3D horse model reconstruction using consumer depth cameras.
- To integrate reconstruction, non-rigid optimization, and automatic body measurement for equine phenotyping.
Main Methods:
- A generative 3D reconstruction pipeline utilizing three consumer depth cameras.
- An image-to-3D module for extracting morphological traits and initial reconstruction.
- Coarse-to-fine non-rigid fitting optimization with dynamic surface feature matching weights to correct geometric distortions and recover scale.
Main Results:
- The pipeline successfully reconstructs high-fidelity 3D horse models with accurate morphological traits.
- Non-rigid registration significantly reduced core body measurement errors and Chamfer Distance (CD) by over 50%.
- The F-Score for reconstruction integrity increased by more than 20% compared to baseline methods.
Conclusions:
- The developed method enables automatic horse body phenotyping with enhanced precision and reconstruction integrity.
- This approach offers a technical reference for 3D dimensional measurement of other livestock species in large-scale precise breeding programs.
