数字人--信息与生命科学结合的新领域

“数字人”（以下不加引号）是通过计算机技术,将人体结构数字化,经过重建和虚拟技术的处理,在电脑屏幕上出现的看得见的、能够调控的虚拟人体形象。研究过程可以分为数字化“可视人”、“物理人”、“生理人”、“智能人”4个阶段。我国在2001年和2003年两次香山科学会议后,启动了这个领域的研究工作,发展较快。现在已有8个中国人数据集报道,不少高校、科研机构、临床科室也进行了开发应用研究。数字人作为新的技术载体,将在航天、体育、影视、国防、医学等众多领域拥有应用发展的空间,当前向有许多急需解决的科学问题和关键技术,如图像分割、神经系统和淋巴系统信息获取,海量数据管理,科学数据共享等。

DIGTAL HUMAN--A NEW RESEARCH FIELD COMBINED INFORMATION AND LIFE SCIENCE

Digital human is a visible, adjustable and controllable virtual human image, which can show on screen. The image was obtained by digitize human structure by computer technology, then reconstructed and processed by virtual technology. The whole process could be divided into the following four periods: digital "Visible Human", "Physical Human", "Physiological Human" and "Intelligent Human". After two Xiangshan Science Conferences in 2001 and 2003, this study was initiated in our country and made great progress. Up to now, there 8 sets of digital Chinese database have been reported, many universities, academic institutes and clinical departments were involved in development study. As a new technology carrier, digital human could be applied in spaceflight, aviation, sports, entertainment, national defense and medicine fields. Currently there are still some unanswered scientific questions and key technology, such as image segment, information obtain from nerve system and lymph system, great capacity database management, scientific data sharing.
