虚拟三维人体解剖学展示系统的设计

背景：应用计算机虚拟技术配合双向交互式人机界面,设立虚拟实验室,使抛弃面对面教学成为了可能。目的：使用虚拟三维技术实现人体解剖学标本演示,在清晰度、质感、素材输入难易度上全面超越常规三维建模方法制作的电子标本,最终实现远程教育网上虚拟解剖实验室的应用。方法：自行开发半自动控制的三维标本数据录入硬件系统,全方位的录入解剖标本、模型的素材资料,形成资料库。用软件系统虚拟三维展示解剖标本、模型,并提供相关文献资料、语音解说等素材。结果与结论：完成了三维标本数据录入机的制作,可以在5min内将一个实体标本转化为数字化图像数据,数据无需处理,直接输入数据库即可通过虚拟三维演示系统实现远程标本立体显示。三维动画相对于传统二维图片,具有立体,直观,使用方便,不会损耗,易于扩展等优点,在人体解剖的教学及医学科普教育上有良好的应用前景。

Design and investigation of virtual three-dimensional display system of human anatomy

BACKGROUND：With developing computer technology,virtual technology enable students to observe the spatial three-dimensional structure,vibrant colors,clear hierarchy,the real texture,and with interactive interface,the establishment of virtual laboratories,and the abandonment of face to face teaching become possible.OBJECTIVE：We demonstrated human anatomy specimens by virtual three-dimensional technology,and made the clarity,texture,importation of the datas easier comparing to traditional two-dimensional modeling,ultimately to bring online-remote-education virtual anatomy laboratory into reality.METHODS：With self-developed semi-automatic three-dimensional specimen data importing hardware system（3DSDIMS）,we make a full range importation of anatomical specimens to form a database.And we setup a display system with software（DSS） providing relevant documents,audio commentary and other material.RESULTS AND CONCLUSION：The 3DSDIMS is functional and capable to convers a specimen into digital image data within five minutes.The data can directly input to the database and can provide demonstration through DSS for remote display.Compared with traditional two-dimensional animation picture,three-dimensional specimens display is easier to use,not consumption,easier to expand,three-dimensional virtual system has a good prospect of teaching in anatomy and medical science education.
