摘要: 针对RSSI指纹膜定位方法受矿井环境影响较大，而基于航迹推算的定位方法易形成误差累积的问题，设计了基于指纹膜与航迹推算的井下人员定位系统。该系统周期性采集人员的位置信息与运动姿态信息，利用K近邻和峰值检测方法求解指纹定位结果和航迹推算结果，并对定位结果进行加权融合得到目标位置。测试结果表明，该系统明显提高了定位精度和稳定性，对煤矿巷道复杂环境具有较强的适应能力。

Abstract: In view of problem that RSSI-based fingerprint positioning method is greatly influenced by environment of coal mine tunnel, and localization method based on dead-reckoning is easy to form accumulation of errors, underground personnel positioning system based on fingerprint and dead-reckoning was designed. The system periodically collects location and attitude information, uses KNN and peak detection method to solve result of fingerprint and dead-reckoning, and the target position was obtained by weighted fusion of the two positioning results. The test results demonstrate that the system can obviously improve positioning accuracy and stability, and has strong adaptability to the complex environment of coal mine tunnel.
