Marek Franaszek, Prem Rachakonda, Kamel S. Saidi
TL;DR
This paper introduces a new method to filter 3D point clouds for robotic bin-picking tasks, improving performance in cluttered scenes.
Contribution
A novel filtering technique tailored for organized 3D point clouds in bin-picking applications is proposed.
Findings
The new filtering method outperforms generic outlier removal on heavily contaminated datasets.
It was tested on six different bin datasets and showed improved filtering efficacy.
Abstract
In robotic bin-picking applications, autonomous robot action is guided by a perception system integrated with the robot. Unfortunately, many perception systems output data contaminated by spurious points that have no correspondence to the real physical objects. Such spurious points in 3D data are the outliers that may spoil obstacle avoidance planning executed by the robot controller and impede the segmentation of individual parts in the bin. Thus, they need to be removed. Many outlier removal procedures have been proposed that work very well on unorganized 3D point clouds acquired for different, mostly outdoor, scenarios, but these usually do not transfer well to the manufacturing domain. This paper presents a new filtering technique specifically designed to deal with the organized 3D point cloud acquired from a cluttered scene, which is typical for a bin-picking task. The new…
