Image Processing Technology of Panoramic Scanning for Orepass
Liu Yanzhan · Mining Research and Development · 2014
The orepass panoramic scanner is an image taking device to detect sidewall of orepass.By analyzing the arrangement of orepass panoramic scanner camera and internal photo environment in orepass,an image clipping and splicing method was proposed to check the orepass diameter variation.The advantages and disadvantages of both the equalization enhancement method and the linear enhancement method for image histogram processing were compared,and then an orepass panoramic image contrast enhancement method was proposed based on the linear enhancement technology.The engineering application results for repairing projected of stage orepass in Wuhan Iron and Steel Group Mineral Company showed that clear panoramic images of orepass sidewall can be obtained through the image stitching and enhancement disposing,which provided a help for the orpass wall's repair and maintenance.
