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 687 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轴可视化的触觉图像，以及一份按序整理所有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进行插值处理，以与视觉图像实现对齐。视觉图像与触觉图像的分辨率均为620×410。本数据集共计687条记录，每条记录包含1张视觉图像、2张分别沿X轴与Z轴的触觉图像，以及1张缺陷分割图像（defect segmentation image）。文件名以x、z结尾的触觉图像分别对应X分量与Z分量。本数据集的样本涵盖丰富的色彩与纹理类型，同时体现了跨模态数据融合的应用优势。作为一种柔性材料，皮革的表面与底面可能存在缺陷，二者可分别通过视觉图像与触觉图像观测得到。结合视觉图像与触觉图像，能够更全面地获取缺陷分布相关信息。
