摘要
针对现有室内导航技术中,室内3维模型构建方法存在对室内某些特殊位置难以识别、小空间导航格网建立困难等问题,提出采用建筑信息3维模型结合Unity 3D平台进行室内3维模型及导航格网构建的方法:基于无线局域网室内定位技术实现室内距离与空间坐标的计算;通过创建网格和楼层线、导入建筑结构图和平面图、创建3维组件,输出文件并转换成可用格式;最后开发室内3维场景导航程序,完成室内定位、路径规划及自动寻路等主要功能。结果证明该方法可以实现室内自动导航。
Aiming at the problem that it is difficult to identify some special interior locations and establish small space navigation grids for indoor 3D model construction in indoor navigation technology,the paper proposed a method that uses building information modeling(BIM)combined with Unity 3D to construct indoor 3D model and navigation grids:the indoor distance and spatial coordinates were calculated based on wireless local area networks(WLAN)indoor positioning technology;and the final files were output to convert usable formats by creating grids and floor lines,importing building structural drawings and floor plans and making 3D components;finally the indoor 3D scene navigation program was developed with the main functions of indoor positioning,path planning and automatic path finding.Result showed that the proposed method could implement the automatic indoor navigation.
