用边缘检测提升透明物体位姿估计精度
Enhancing Transparent Object Pose Estimation: A Fusion of GDR-Net and Edge Detection
- 在预处理阶段引入边缘检测，增强透明物体检出特征
- 使用Trans6D-32K数据集测试，部分物体位姿误差降低15%
- 适合做机器人视觉中透明物体感知的研究者参考
透明物体的位姿估计在机器人视觉中仍具挑战性，主要受光照、背景和反射影响。然而，透明物体的边缘具有最高对比度，可提供稳定显著的特征。本文提出一种新方法，在物体检测与位姿估计前加入边缘检测预处理。通过实验考察不同边缘检测器对透明物体的影响，评估了当前先进的6D位姿估计框架GDR-Net与目标检测器YOLOX在应用Canny（含/不含颜色信息）及全嵌套边缘（HED）作为预处理时的表现。基于物理渲染数据集Trans6D-32K，采用BOP挑战赛提出的参数进行评估。结果表明，引入边缘检测预处理能有效提升特定物体的检测与位姿估计性能。
原文摘要 · Abstract (English)
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.
