基于CSI众包数据的室内路径生成算法
Indoor Path Plan Generation Algorithm Based on CSI Crowdsourcing Data
摘要
Abstract
Traditional floor plan construction suffers problems of high trajectory energy con sumption and large cumulative error.Therefore,this paper proposed a new construction method without using sensors but useing Wi-Fi signal to sense the movement of people to construct an ac cessible path structure so as to draw the final indoor plan.The experimental results show that the method of using CSI to detect the path structure in indoor environment is more accurate and low cost,and the precision of the constructed floorplan achieves an average of 87％,and the structure of floorplan is complete enough to be suitable for indoor location service.关键词
