An object positioning system includes an object positioning device and a detecting device. The object positioning device includes at least a magnetic bar forming a marked magnetic field. The detecting device includes a magnetic field generating unit for outputting a detecting magnetic field according to a detecting signal in an electromagnetic conversion process, and an analyzing unit for detecting whether the detecting signal varies when the detecting magnetic field passes the marked magnetic field along a moving direction. The analyzing unit analyzes whether a character of the variation corresponds to the marked magnetic field and accordingly outputs a detecting result. When people are trapped under snow or collapsed buildings because of an avalanche or an earthquake, the system can be utilized to find out trapped people. The system can also be utilized to find out objects buried underground. Money and time consumed by mass excavation can be saved. |
