A New non-contact control/measurement system for free-sailing model ships is developed, which will be applicable for various free-sailing tests. It was difficult to carry out by conventional radio-control system. The system is consists of a micro-computer system installed in a model ship, which is communicated with a personal computer on land via a set of wireless modems. The personal computer will order the micro-computer to control and measure through A/D, D/A and DIO boards, which are connected with a propeller, a rudder and sensors.Another system is position measurement system using two VIDEO cameras, utilizing image processing and ordinate transformation of a point light on a model ship. In cases where displacement of a model ship is insufficient for instruments, this system will be a merit. Six degree of freedom measurement is possible, if this system will be combined with the gyro signal measured by the nonーcontact control/measurement system.The system is applied to the following experiments with great success.1) Capsizing tests in regular following seas in a towing tank (where water-proofness, impact force torelance, six-degree-of-freedom measurement capability and the fundamental system check were done.)2) Capsizing tests in regular/irregular following seas in an outdoor model basin (where outdoor capability of digital communication was done ; position measurement using VIDEO cameras was not done here.)3) Manoeuvrability tests in still water in an outdoor model basin (where position measurement using VIDEO cameras was done.)

开发了新型非接触式自由航行模型船控制/测量系统，适用于各种自由航行试验。通过传统的无线电控制系统很难实现。该系统由安装在模型船上的微型计算机系统组成，该系统通过一组无线调制解调器与陆地上的个人计算机进行通信。个人计算机通过A/D、D/A和DIO板命令微机进行控制和测量，这些板与螺旋桨、舵和传感器相连。另一个系统是使用两个视频摄像机的位置测量系统，利用模型船上点光源的图像处理和坐标变换。如果模型船的排水量不足以容纳仪器，则该系统将是一个优点。如果该系统与非接触控制/测量系统测量的陀螺仪信号相结合，则可以进行六自由度测量。该系统应用于以下实验并取得了巨大成功。1）在拖曳池中定期进行以下海域的倾覆试验（进行了防水性、耐冲击力、六自由度测量能力和基本系统检查。）2）在拖曳池中进行了倾覆试验。 在室外模型盆地中进行定期/不规则的跟随海洋（其中进行了数字通信的户外能力；此处未进行使用视频摄像机的位置测量。）3) 室外模型盆地中的静水中的机动性测试（其中使用视频摄像机进行了位置测量。）
