Enhancing Transparent Object Pose Estimation: A Fusion of GDR-Net and Edge Detection
This addresses a challenging task in robot vision for transparent objects, but it is incremental as it builds on existing methods with a pre-processing modification.
The paper tackled the problem of transparent object pose estimation by incorporating edge detection as a pre-processing step for GDR-Net and YOLOX, finding that it enhances performance for certain objects.
Object pose estimation of transparent objects remains a challenging task in the field of robot vision due to the immense influence of lighting, background, and reflections. However, the edges of clear objects have the highest contrast, which leads to stable and prominent features. We propose a novel approach by incorporating edge detection in a pre-processing step for the tasks of object detection and object pose estimation. We conducted experiments to investigate the effect of edge detectors on transparent objects. We examine the performance of the state-of-the-art 6D object pose estimation pipeline GDR-Net and the object detector YOLOX when applying different edge detectors as pre-processing steps (i.e., Canny edge detection with and without color information, and holistically-nested edges (HED)). We evaluate the physically-based rendered dataset Trans6D-32 K of transparent objects with parameters proposed by the BOP Challenge. Our results indicate that applying edge detection as a pre-processing enhances performance for certain objects.
