摘　　要：介绍了一种基于多彩色CCD设备的同步拍摄,并通过图像处理与PTV技术建立对浮冰运动进行测量的系统。为跟踪更大范围的浮冰运动情况,采用多彩色CCD设备对运动的模拟浮冰进行连帧拍摄,通过边缘提取、轮廓跟踪等图像处理方法获得浮冰形状参数;根据逐帧的PTV计算,获得浮冰的速度。试验测试结果表明,此方法可以精确地计算浮冰运动相关物理参数及运动轨迹,可应用于模型试验中的浮冰运动测量。A floating ice movement measuring system based on synchronous photograph with multi-color CCD device was introduced. The measures the movement of floating ice system was set with the technology of image processing and PTV. The simulation motion of the floating ice is photographed continuously using the multi-color CCD device to trace the ice in the large range. The shape parameters of the floating ice is obtained by the image processing method of edge detection and contour tracking. With the image frame, the velocity of ice can be calculated using PTV algorithm. The experiment results show that the developed system which can calculate the physical parameters and trajectory precisely can be applicable for the floating ice motion measurement in the physical experiments.
