Pedestrian navigation device and method using heading information of terminal |
摘要 |
A pedestrian navigation device and method uses heading information of a terminal to measure a location. Moving direction information and x, y, and z-axis acceleration values of the terminal are detected. Heading information is calculated using the moving direction information of the terminal. Validity of the heading information is determined using the detected x, y, and z-axis acceleration values, making it possible to more accurately estimate the location of the pedestrian. |
