摘要:: 传统医院分工过于专业化，就医流程割裂，在没有良好导诊服务的条件下病人就医十分不便。随着信息化的发展，越来越多的医院开始建设信息化导诊平台，但目前已有的导诊平台功能仍不够全面。本文的导诊系统对厦门中医院总院门诊片区进行三维模拟，具有行走、漫游、自动导航、医院介绍、科室介绍等功能。系统基于WINDOWS平台开发，使用3DMAX、MAYA等进行三维建模，在Unity3d中实现互动。其中互动的核心在于自动导航，主要使用A*算法，根据医院内物体相对固定、道路纵横交错的特点采用曼哈顿启发函数，简化了算法。该系统有效帮助患者了解就医环境，而且系统操作简单直观，便于各种阶层的患者使用。

Abstract:: The traditional hospital division is too professional and medical treatment process separates. In the absence of good consultation service, patients are very inconvenient. With the development of information technology, more and more hospitals begin the construction of consultation system, but the function of these systems is still not comprehensive. The consultation system in this paper is used for 3D modeling of the Chinese Traditional Medicine Hospital of Xiamen, with walking, roaming, automatic navigation, hospital department introduction and other functions. The system is based on Windows platform, using 3DMAX, MAYA to build 3D models, and interaction is implemented in Unity3d. The core of interaction is automatic navigation. It use A* algorithm. According to the relative fixation of the objects in the hospital and the crisscrossing of the road, the heuristic function of Manhattan is adopted to simplify the algorithm. The system can effectively help patients understand the medical environment, and the operation of the system is simple and intuitive, which is convenient for patients among different ranks.
