CHL_Visual_Tactile_Dataset

The dataset contains raw visual images, visualized tactile images along the X- and Z-axes and an Excel file that organize every sample and their correspondence in order. The tactile images are interpolated on the raw haptic signal to align with the visual images. Both the visual and tactile images have identical resolution of 620 X 410. The dataset consists of 743 records. Each record includes one visual image, two tactile images along the X and Z axes, and one defect segmentation image. Tactile image filenames ending with x and z denote X and Z components respectively.The samples in the dataset exhibit a wide range of colors and textures. Moreover, the dataset demonstrates the advantage of cross-modal data fusion. As a flexible material, leather may have defects on its surface and underside, which can be observed in the visual and tactile images, respectively. Combining visual and tactile images provides better information on the distribution of defects

本数据集包含原始视觉图像、沿X轴与Z轴生成的可视化触觉图像，以及一份用于有序整合各样本及其对应关系的Excel文件。触觉图像已基于原始触觉信号完成插值处理，以实现与视觉图像的空间对齐。视觉图像与触觉图像的分辨率均为620×410像素。本数据集共计743条记录，每条记录包含1张视觉图像、2张分别对应X轴与Z轴的触觉图像，以及1张缺陷分割图像。文件名以x、z结尾的触觉图像分别代表X轴分量与Z轴分量。数据集涵盖的样本具备多样的色彩与纹理特征。此外，该数据集可有效体现跨模态数据融合的应用优势。作为柔性材料的皮革，其表面与底面可能存在缺陷，分别可通过视觉图像与触觉图像观测获取。融合视觉与触觉图像，能够更全面地获取缺陷分布的相关信息。
