【摘要】 提出了一种新的基于激光、CCD成像技术的非接触式带钢平坦度检测方法———激光角度位移法。该方法兼有激光位移法和激光光切法优点:具有激光测量方法结构简单、无损带钢表面、易于维护和容易实现在线数据处理的特点,且使用线激光源照射到被测带钢表面上形成的高亮度的线光斑,使得CCD摄像机可一次得到该线光斑上所有点的位置数据,从而提高测量的速度和效率,并且可以根据需要提取相应的板形信息用于实现板形控制,可广泛适应于冷轧和热轧的生产。更多还原

【Abstract】 The paper proposes a new non-contact strip flatness detection method-laser-angle method which is based on the laser and CCD image technology.The method’s advantages are that its construction simple,non-destructive strip surface,easy to maintain and on-line data processing as the common laser methods.It’s features are that the CCD camera can get all the information on the shape of the measured strip along the width direction and It is easy to get the information which are needed.It can be widely used in the hot and cold rolling production.更多还原
