中文摘要：

为了研究风浪中船舶以及海洋结构物的运动响应，需要在模拟试验时跟踪模型的位置，测试模型在不同类型波浪中的响应，并对模型的六自由度运动进行捕捉和动态测量。比利时KRYPTON公司的K600-DMM是一种新型光学非接触式运动测量系统，利用高精度的照相机和快速图像处理器对被测模型实时的拍照分析，从而计算出模型的位置、姿态、位移、速度的变化。该法具有实时性好、效率高、精度高、测点多的特点，克服了目前采用传感器的缺点，在动态捕捉测量方面，具有广阔应用前景。

英文摘要：

In order to research the motion responses of ship and ocean structure in sea, position tracking of the model is necessary during the model testing in a towing tank. Therefore dynamic measuring can be carried out for six-degree motion. K600-DMM made in KRYPTON Company in Belgium was a non-contacting motion measuring. system which was based on optical theory. The system could take live photos by high-accuracy camera and picture-treating devices. Thus the position, displacement and velocity difference of the moving model could be obtained with a high efficiency and good results. The above system has a far-reaching application in dynamic measurement comparing with the existing sensors.
