What is Poseless-3B?
Poseless-3B represents a groundbreaking approach to hand pose estimation that eliminates the traditional requirement for explicit pose estimation. Built on the Qwen 2.5 3B Instruct architecture, this model directly maps 2D images to joint angles using an innovative projected representation approach, making it particularly valuable for robotics and computer vision applications.
Implementation Details
The model leverages a sophisticated synthetic data pipeline that generates training examples through randomized joint configurations and domain-randomized visual features. It processes monocular images and outputs precise joint angles in radians, represented in XML format for 24 different joint positions.
- Direct image-to-joint angle mapping without intermediate pose estimation
- Zero-shot generalization capabilities for real-world scenarios
- Cross-morphology transfer between robotic and human hands
- Synthetic data training pipeline for robust performance
