Underground personnel positioning system based on fingerprint and dead-reckoning

More Information
  • 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.
