视频测速技术在煤矿井下机车定位中的应用

Application of Speed-measured Technology by Video in Locomotive Location of Coal Mine Underground

针对传统的矿井信集闭系统因采用传感器获取机车运行信息来实现机车识别与定位而导致的系统不稳定问题,介绍了一种采用视频测速技术来实现井下机车定位的方法。该方法采用双目立体视觉测距技术得出机车运行距离,根据相邻两帧图像时间间隔求出机车实时运行速度,然后将机车运行速度转换为相应模拟小球的移动速度,使调度员在调度室内通过观察模拟小球的移动状态来实时监测移动小球对应机车的运行状态,从而实现对机车的定位功能。

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.
