The Method to Acquire the Mine Shaft Coal Bin

When using the pattern recognition technology to monitor the mine shaft coal bin coal level, we must use the effective image acquiring method. In view of complex, the bad working conditions, this article firstly proposed the assistance photo source illumination method to acquire the mine shaft coal bin coal level image. First introduced examination principle to acquire the coal level image, then we have given the establishment and the choice definition condition of the assistance photo source and the CCD(Charge Coupled Device is charge-coupled device) camera. Through the theoretical analysis and the computation, finally we indicated acts according to these definition condition choice and establishment of the photo source and the CCD camera. It shows that may acquire coal level image effectively.
