Diffusion Based Optimal Grasp Detection
Abstract
This project implements a diffusion-based optimal grasp detection system. It takes an RGB-D image as input and segments the point cloud of the object. This segmented point cloud is then fed into a diffusion-based grasp algorithm, which scores potential grasps. The system performs collision-free grasp detection and identifies the optimal grasp, which is then executed in a real-world or simulation environment.
Technical Implementation
Algorithm Pipeline
- Input: RGB-D Image
- Preprocessing: Point cloud segmentation of the object
- Core Algorithm: Diffusion-based grasp generation
- Evaluation: Scoring for collision-free and optimal grasps
- Execution: Real-world or simulation environment
