摘　　要：目前,传统室内定位技术主要基于单个移动终端以及WiFi或蓝牙信标进行指纹匹配定位,精度不高。本文提出一种利用多终端进行协同定位的方法,通过建立信号传播模型量化协同观测量,进而对移动终端匹配定位坐标和协同观测量进行联合平差。试验结果表明,多终端协同定位相较于单终端匹配定位,定位精度提高了25%—30%。At present, traditional indoor positioning technology is mainly based on a single mobile terminal and WiFi or Bluetooth beacon for fingerprint matching and positioning, but the accuracy is not high. This paper proposes a method based on multi-terminal cooperative positioning, which establishes a signal propagation model to quantify the cooperative observations, and then performs a joint adjustment of the mobile terminal’s matching positioning coordinates and the cooperative observations. The test results show that the accuracy of multi-terminal cooperative positioning is increased by 25%-30% as compared with the single-terminal positioning.
