Contactless Palm vein dataset

The data used in this study was gathered from various practical applications, specifically sourced from an access control device that incorporates a hardware module. Meanwhile, the data acquired through sampling conducted under 850nm light. The hardware device itself was utilized in diverse scenarios, encompassing indoor and outdoor environments, with and without background influences. Users participated in the data collection process by placing their palms naturally onto the device for multiple captures. During these captures, users were instructed to move within a range of 5-20cm, rotate their palm 360°, and tilt it at angles of up to ±45°. This methodology ensured a comprehensive dataset for analysis evaluation.

本研究所用数据采集自多个实际应用场景，具体来源于一款集成硬件模块的门禁控制装置。同时，该数据的采样环节是在850nm光照条件下完成的。该硬件设备被部署于多种场景中，涵盖室内、室外以及存在背景干扰和无背景干扰的环境。参与数据采集的用户需将手掌自然放置于设备上进行多次采集操作；采集过程中，用户需按照要求在5-20cm的范围内移动手掌、完成360°旋转，并将手掌倾斜至最大±45°的角度。该数据采集方案确保了可用于分析与评估的全面数据集。
