【摘要】 作为视频测量系统的图像处理部分,线段提取具有重要意义。当目标线段附近存在较多无序干扰线段时,霍夫变换提取直线段的方法出现了严重失效,在文献[2]提出的标记生长算法的基础上,引入了对方向因子的判断,并与文献[1]提出的螺旋线法相结合应用于靶场视频测量系统中的图像处理部分,有效的提取了目标物体的上下边缘线及标志线,为测量目标提供了一条较好途径。更多还原

【Abstract】 As the image processing part of video measure system, line segments extraction is very important. When there are many other lines among the object lines, Hough transformation becomes invalid to distill the object lines. Based on the labeling and growing algorithm mentioned in document 2, this paper introduces the estimation of direction factor, and uses the algorithm with the spiral algorithm in the digital image processing part of TV monitor system. The outline and mark-line of object can be efficiently distilled by using this method, and thus it provides a fine method in monitoring object.更多还原
