中文摘要：

为了实现热轧带钢端部形状检测，利用Matlab中视觉图像处理工具箱，建立了南CCD线阵相机构成的双目立体视觉系统模型和实际带钢生产线上的运动过程模型。热轧带钢在生产过程中会受到粗轧辊的不平均压力的影响，从而造成带钢头尾变形。针对这种情况，提出了一种新的带钢末端形状视觉检测和宽度计算方法。该方法不但可以在带钢发生平移、倾斜等位置和姿态变化情况下仍能够准确测量出带钢宽度，并且可以精确还原出带钢头尾形状。仿真试验结果证实了所提出的视觉模型和算法的有效性，取得的结果令人满意。

英文摘要：

To realize the detection of shape of the ends of hot rolled strip steel, by adopting the toolbox of visual image processing in Matlab, the binocular stereo vision system model composed of CCD linear array camera, and the motion process modelof practical production line of strip steel are established. In production process, the due to the uneven pressure of rough rollers, the head and tail of the hot rolled strip steel are deformed often. Aiming at this situation, the new visual detection and width calculation method for shape o the ends is proposed. The method can precisely measure the width of strip steel, even under position or posture is changing with shift or tilt, and the shapes of head and tail of the strip steel can be restored. The results of simulation show the effectiveness of the visual model and the proposed algorithm, and the results obtained are satisfactory.
