摘要
为了提高移动终端定位精度,实现室内自动导览功能,本研究结合WiFi指纹定位和传感器惯性导航的优点,提出一种WiFi指纹辅助的惯性导航室内定位技术。采用图像识别或WiFi进行初始定位,通过惯性导航推算行人行进位置,并定期使用WiFi对惯性导航进行起始位置更新。结果表明,该定位技术能够有效提高室内定位精度。
In order to improve the positioning accuracy of mobile terminal and realize the function of indoor automatic navigation,the research combines the advantages of WiFi fingerprint positioning and sensor inertial navigation,and proposes a WiFi fingerprint assisted indoor location technology of inertial navigation.First,image recognition or WiFi is used for initial positioning.Estimation of pedestrian position is done by inertial navigation,and WiFi is regularly used to update the starting position of inertial navigation.The result shows that the positioning technology can improve the indoor positioning accuracy.
