【摘要】 图像处理已在现如今的生产生活当中越来越多的被我们认识,其中对于图像的无缝拼接技术更是被广泛应用。图像拼接技术在太空探索,海底调查,医疗,气象,地质勘探,军事,视频压缩和存储,视频索引和检索,三维物体重建,等领域得到了广泛的应用。在高炉冶炼过程中,控制炉内冶金材料料面的燃烧状态和分布情况对掌握和了解的气体流量控制材料表面的分布状况、指导正确的高炉操作是非常重要的,但通常电子监控设备一次成像的区域有限,很难帮助我们对整体料面情况做出判断。本文提出了一种设计方案,以高炉料面监控的数字成像图片为基础,通过在炉喉部位开设风孔观测炉内实时情况。首先,先建立了监控系统的总体方案,尤其是由于风孔位置的选择可不同于以往在顶部的开设,使画面不再是顶部俯视料面,而是由侧上方直接观测,克服了由于俯视料面而无法获得具体料面堆叠状况的弊端;其次,再利用图片拼接技术完成整个料面实际的广视角全景图像,CCD驱动平台帮助摄像头获取图片资料,再利用计算机完成图像的无缝拼接。利用淡入淡出的融合算法,消除了重叠像素的亮度差异而造成的误判,以达到无缝拼接的根本目标。最终获得一副反映料面立体形状的广角全景图像,帮助人们对炉内的炉内生产状态及料面情况做出准确的判断。

【Abstract】 Image processing in the production is now more and more known where the image of the seamless splicing technology is widely used. Image stitching technology have been widely used in space exploration, seabed surveys, medical, meteorological, geological exploration, military, video compression and storage, video indexing and retrieval, three-dimensional object reconstruction, and other fields.In the blast furnace process, it is very important to get the surface of the furnace combustion of metallurgical materials, material status and the gas flow by control the distribution of surface materials to guide the correct operation of blast furnace. But usually an electronic monitoring area is limited, it is difficult to help us make the overall situation to determine situation of the surface material.This paper presents a design, the surface charge monitor with high picture-based digital imaging, site set up by the furnace throat hole the wind real-time observation of the furnace. First of all, establish a monitoring system of the overall program, particularly because the wind hole may be different from the previous selection of the opening at the top, the screen is no longer at the top overlooking the material surface, but by the side of the top of the direct observation, to overcome the drawbacks of stacked material surface which caused by overlooking the specific situation view. Second, by re-use photo stitching technology, the wide viewing angle panoramic images of the material surface are finished actually. The driven platform of CCD camera is used to help get pictures, then we use the computer to complete the image without seam stitching. By fusion algorithm, we eliminate overlapping pixel intensity differences caused by miscarriage of justice, in order to achieve the fundamental goal of seamless. Ultimately, a three-dimensional shape of the surface material to reflect the wide-angle panoramic images to help people to make accurate judgments on the state of the furnace and furnace material side of production.
