室内微型组合导航计算机设计

Indoor micro integrated navigation computer design

通过对室内导航技术的分析,结合嵌入式控制技术和和微机电系统(micro electro mechanical systems,MEMS)技术,提出了基于MEMS惯性/视觉的室内微型组合导航计算机设计方案。该方案以室内导航的性能需求为基础,设计了以MEMS惯性传感器和摄像头为主要传感器电路,并融合各模块数据完成了计算机系统设计。测试结果表明该系统能够正确采集前方障碍物的距离信息和运动信息,体积小,可靠性高,满足室内导航的要求。

By analyzing the indoor navigation technology,this paper proposed a indoor navigation computer which integrated the MEMS inertial/visual information by using the embedded control theory and MEMS technology.Based on the requirements of indoor navigation,the paper designed a multi sensors computer system which combined the MEMS inertial sensors and camera sensor.Experimental tests validate this system can collect the motion information of obstacles and distance information correctly.
