    • An independent tube position verification system includes a TV camera (16) mounted on an end effector (EE) of a robotic arm (20) mounted in a steam generator (10) beneath the tube sheet (12) to visually track changes in position as the end effector (EE) is moved across the tube sheet (12) by a robotic arm (20). The tube sheet (12) and the tube ends (14) thereof are illuminated by one or more light sources (18) at an oblique angle to cause the desirable presence of shadows in the field of view. The TV camera (16) outputs successive image frames so that displacement of a artifact in the image field in successive frames yields physical displacement information which is converted into velocity and direction information. Changes in position determined by the verification system are compared against position information maintained by the robotic arm (20); any mis-match indicates a loss of tracking integrity requiring a system re-calibration.
    • 独立管位置验证系统包括安装在安装在管板(12)下方的蒸汽发生器(10)中的机器人臂(20)的末端执行器(EE)上的电视摄像机(16),以可视地跟踪位置变化 端部执行器(EE)通过机械手臂(20)移动穿过管板(12)。 管板(12)及其管端(14)由一个或多个光源(18)以倾斜角度照射,从而在视野中产生希望的阴影存在。 电视摄像机(16)输出连续的图像帧,使得连续帧中的图像场中的伪影的位移产生被转换成速度和方向信息的物理位移信息。 将由验证系统确定的位置的变化与由机器人臂(20)维护的位置信息进行比较; 任何错误表示丢失跟踪完整性,需要进行系统重新校准。
