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5 min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.
