摘　　要：近年来室内定位技术的逐渐被关注也带动了对室内地图的需求,但是室内地图由于多种原因并无法及时获得精确的室内地图,所以室内地图的挖掘构建也是一个重要的研究方面。提出了一种利用移动终端传感器进行的多模获取室内地理信息特征点,并绘制室内地图的系统。系统通过加速度传感器,陀螺仪的读数特征识别电梯、楼梯、转弯、室内静止点等点,利用无线路由器信号读数变化特征,获取读数峰值,利用用来获取室内走廊以及房间形状,进而绘制出较为精准的室内地图。Recent years indoor localization got more focus, which promoted the requirement of indoor map. However accurate indoor map can not be accessed all the time because of some reason. Indoor map construction is a valuable research. This paper designed a system leveraging common sensors embedded in mobile devices to get indoor geographic information points and draw the indoor map. The system recognize elevators, stairs, corners and room static points by analyzing fearures of the readings of accelerator, gyroscope, and get the WiFi peak by the readings of WiFi scanner. With these kinds of points the system can construct the shape of corridors and rooms, and generate accurate indoor maps.
