Study and application of the computer vision-based intelligent medium adding system

The problems faced by Fucun Coal Preparation Plant in the use of the traditional medium adding system are high labor intensity, high risks and inability to measure the adding quantity. To deal with the situation , an intelligent medium adding system is developed through integration of the 3-dimensional reconstruction, laser positioning, PID control and anti-sway technologies with the computer vision technology as the core. The use of the system makes it possible to have the medium added automatically. Practice shows that with the use of the system, the whole process starting from preparation of thick medium down to addition of make-up qualified medium can be automatically executed in an unattended manner, and the medium loss incurred during the medium adding and preparation processes can be cut by 50%.
