摘　　要：高精度的室内定位系统可以极大地拓展定位应用的范围,文章对基于图标成像的室内定位方法进行了系统研究,利用分布在室内空间的图标与其所成像的位置关系,对待定位点进行高精度的室内定位。该系统由图标、成像处理模块、定位计算3部分组成,成像处理模块完成图标成像和光电信号转换的功能,定位计算完成图标成像点位置确定、图标识别、定位图标优选和待定位点位置坐标计算等功能。仿真实验结果表明,系统的定位精度可以达到厘米量级。A high-precision indoor positioning system can greatly expand the scope of positioning applications.This article systematically studies the indoor positioning method based on icon imaging,using the relationship between icons distributed in indoor space and their imaged positions to achieve high-precision indoor positioning of the target location.The system consists of three parts:icon,imaging processing module,and positioning calculation.The imaging processing module completes the functions of icon imaging and photoelectric signal conversion.The positioning calculation completes the functions of icon imaging point position determination,icon recognition,positioning icon selection,and coordinate calculation of the position of the point to be positioned.The simulation experiment results show that the positioning accuracy of the system can reach the centimeter level.
