Biometrics technology is one of the most important and effective solutions for personal authentication. In recent years, as one of the emerging biometrics technologies, dorsal hand vein (DHV) biometrics has received a lot of attention. In fact, DHV biometrics has been studied for more than 30 years, during which different problems related to DHV recognition have been addressed. In this paper, we conduct a comprehensive survey on the state-of-the-art in DHV biometrics. Nearly all important aspects of DHV biometrics have been summarized, including the developmental history, data acquisition, databases, preprocessing algorithms, feature extraction and matching algorithms, information fusion schemes and commercial products. We also discuss the challenges and future directions in DHV biometrics research.

生物识别技术是个人身份验证最重要和最有效的解决方案之一。近年来，作为新兴的生物识别技术之一，手背静脉（DHV）生物识别技术受到了广泛的关注。事实上，DHV 生物识别技术已经研究了 30 多年，在此期间已经解决了与 DHV 识别相关的不同问题。在本文中，我们对 DHV 生物识别技术的最新技术进行了全面调查。DHV生物识别几乎所有的重要方面都已被总结，包括发展历史、数据采集、数据库、预处理算法、特征提取和匹配算法、信息融合方案和商业产品。我们还讨论了 DHV 生物识别研究的挑战和未来方向。
