首个可3D打印的触觉纹理数据集,支持跨设备公平比较传感器。
A 3D-Printable Dataset for Fair Testing and Comparisons of Tactile Sensors

- 用数学函数生成6种可控纹理,适配不同打印机和材料。
- 高精度打印机打印的纹理触觉信号更一致,误差更低。
- 适合触觉传感器评测、机器人感知研究者使用。
现有触觉感知纹理数据集多基于特定传感器对实际表面的读数,而非描述纹理本身,导致传感器间难以公平比较,且研究难复现。本文提出首个可3D打印的数学定义纹理数据集,包含六种由正弦波与傅里叶函数组合生成的表面图案,可控调节空间频率、振幅和方向结构。通过在三款主流3D打印机上使用多种耗材打印,并在受控接触条件下用光学TacTip传感器采集图像,评估其可复现性。结果表明,打印质量(尤其峰值锐度和线状残留)显著影响触觉信号方差,高端打印机产生的信号更一致。神经网络与PCA模型分类实验显示,高质量打印支持良好机内泛化,但跨打印机泛化仍因几何不一致而困难。本工作建立了首个公开可用、物理可复现的3D打印触觉纹理基准,为触觉传感器公平比较提供基础。
原文摘要 · Abstract (English)
Existing texture datasets for tactile sensing primarily consist of sensor readings from a specific sensor interacting with available surfaces/objects rather than describing the textures themselves, limiting fair comparison between tactile sensors and hindering reproducible research. In this work, we introduce a 3D-printable dataset of mathematically defined textures designed to be fabricated reliably across different printers and filament types. The dataset consists of six parametrically generated surface patterns derived from combinations of sine-wave and Fourier-based functions, giving controlled variation in spatial frequency, amplitude, and directional structure. We evaluate the reproducibility of these textures across three popular 3D printers and multiple filament types by measuring variance in images captured using an optical TacTip sensor under controlled contact conditions. Our results show that print quality, particularly peak sharpness and stringing, affects tactile variance, with higher-end printers producing significantly more consistent signatures. Classification experiments using neural networks and PCA-based models further demonstrate that high-quality prints support strong within-printer generalisation, while cross-printer generalisation remains challenging due to geometric inconsistencies. This work establishes the first openly available, physically reproducible 3D-printed texture benchmark, providing a foundation for fair comparison of tactile sensors.
