| 摘 要： | 设计了一套适用于铁路平交道口运动目标视频检测的软件系统.采用轮廓提取和改进的Hough变换成功提取出复杂背景下不容易检测正确的铁轨直线;通过定间隔邻帧差检测有无运动目标出现,减少了运算量、减少了误判;通过计算目标中心与铁轨直线的距离进而判定此距离的变化趋势,很好地检测到目标的运动趋势.对多因素进行综合评判,从而实现智能视频检测报警.还对阈值的选取进行了探讨,对影响阈值的因素进行了分析.

| Abstract: | The paper introduces a software system designed for video detection of moving object at railway crossing.The railway line even under complex background was successfully extracted with contour extraction and improved Hough transform method.By using adjacent frames-difference method at reasonable intervals,both computational load and misjudgment were reduced when detecting the appearance of moving objects.After calculating the distances between object centers and the railway lines the change tendency of the d... |
