摄像机标定法在煤矿皮带速度检测中的应用

urrently,the monitoring of belt system in coal mine are mainly by PLC and sensors. Its test accuracy is not very high. And the information provided by under mine video equipments is only judged in the monitoring room manually. There are also security risks. According to these drawbacks ,this paper proposes an intelligent real-time monitoring system of belt speed based on the camera calibration, and bring forward the overall construction of the system and the flow chart to implement it. And then focus on real-time belt speed detection algorithm and its implemention. We use the information provided by real-time video to compute belt speed. This improved means of real-time belt speed collection and maximized the function of the installed video cameras. The experiment result shows that this method has very high accuracy and improves automation and modernization of production and management in coal mine.
