Application of Speed-measured Technology by Video in Locomotive Location of Coal Mine Underground
Abstract
In order to solve unstability problem of signaling centralized and locking system in mine which uses sensors to distinguish and locate locomotives, the paper introduced a method of locomotive location of coal mine underground by use of speed-measured technology by video. The method uses distance-measured technology of binocular stereo vision to get running distance of locomotive, obtains real-time running speed of locomotive according to interval of two sequential images, and converts the running speed of locomotive to moving speed of a corresponding simulated ball, thus dispatchers can monitor running status of locomotive through observing moving status of the simulated ball, namely the method can realize function of locomotive location.
