摘要:

在工业质量控制与维护阶段的表面重建应用及缺陷检测场景中,大规模表面扫描有着广泛需求。传统视觉式触觉传感器虽在高分辨率形状重建中表现出良好性能,但存在传感面积小、在表面滑动时易损坏等局限,不适用于大表面的连续传感。为解决这些不足,我们提出了一款专为连续表面传感应用设计的新型视觉式触觉传感器。该设计采用弹性带与两个滚轮对目标表面进行连续扫描。所提传感器在形状重建与表面融合两方面均取得了良好结果,证明了其适用性。我们报告了传感区域内以及不同扫描速度下,估计表面法向图与参考表面法向图的点积结果。结果表明,该传感器能以最高45 mm/s的速度高精度快速扫描大规模表面。

英文摘要:

Scanning large-scale surfaces is widely demanded in surface reconstruction applications and detecting defects in industries' quality control and maintenance stages. Traditional vision-based tactile sensors have shown promising performance in high-resolution shape reconstruction while suffering limitations such as small sensing areas or susceptibility to damage when slid across surfaces, making them unsuitable for continuous sensing on large surfaces. To address these shortcomings, we introduce a novel vision-based tactile sensor designed for continuous surface sensing applications. Our design uses an elastomeric belt and two wheels to continuously scan the target surface. The proposed sensor showed promising results in both shape reconstruction and surface fusion, indicating its applicability. The dot product of the estimated and reference surface normal map is reported over the sensing area and for different scanning speeds. Results indicate that the proposed sensor can rapidly scan large-scale surfaces with high accuracy at speeds up to 45 mm/s.
