Computer automatic measuring visual system for stock ground measuring

Abstract

The invention relates to a computer automatically measuring visual system for stock yard. The CCD camera is set at the location that has a certain height to the two end faces of the stock yard as high location collection point to collect the panorama image of the stock yard. The CCD set on the moving bogie of stocking and reclaiming equipment sets moving visual collection point of the stocking and reclaiming equipment. All of the CCD camera image signals transmit to image collection card through the video cable. The image collection card connects to image processing front end by PCI bus, and takes image digital information expression before image processing. The image digital expression from the image process front end realizes alternating of the image information by IEEE1394 protocol interface connecting to up computer. The 3D geometry size of the measured stock yard would be realized and output. The invention realizes the digital distilling for stock yard image information, and achieves the whole process management and operation automatic level for material stocking and reclaiming.

Description

technical field [0001] The invention relates to a system in the technical field of image processing, in particular to a computer automatic measurement vision system for stockyard measurement. Background technique [0002] "Stock yard automation" refers to the automation technology for the whole process of raw material storage, withdrawal, real-time inventory calculation, site planning, and feeding plan. Regardless of ironmaking enterprises or thermal power plants, raw materials or solid fuels are always the "grain" of enterprises. With the accelerated pace of economic globalization, energy saving and benefits have become the basic performance indicators for evaluating the optimal management of enterprises. It is not enough to understand the automation of mechanical equipment. At present, many processes in stockyard management, such as: stackers for material accumulation, reclaimers for reclaiming materials, stockyard management, stockyard real-time inventory, etc., still la...

Problems solved by technology

Since the invention uses CCD to take images of the material pile from more than 4 different directions such as 0°, 45°, 90°, and 135°, the distance between the material pile and the camera is required to be fixed, and a scale is set beside the material pile , its application conditions are very cumbersome and harsh, and the measurement error is relatively large, which has great limitations
