Developmental study of morphometry system for marine organisms using ROV

为了研究海洋动物的形态测量学，我们研制了一种水下视频系统中的数码相机系统。使用该系统，可以粗略估计海洋动物的大小，而无需手工或捕鱼工具捕获动物。该系统的独特之处在于在远程操作车辆（ROV, Mitsui Zosen, RTV-100MKII）上安装了数码相机。ROV中的摄像机和数码摄像机连接到安装在船上的操作系统和监视器。拍摄完成后，数码相机中的MO图像数据可以方便地从船上的ROV传输到个人计算机。近年来，数码相机在识别小型海洋动物方面的分辨率得到了迅速的提高，我们的数码相机系统是代替水下摄像机进行形态测量的有力技术手段。该系统还可用于对海洋生物进行分类学、形态学、环境学和环境保护等综合调查，了解海洋生态。对于尺寸的计算，我们使用了一个用于制作CG动画和beta cam视频录制系统的营销软件“Composer”，但最后我们使用了一个流行的营销软件“Photoshop”，用于从录像带数据中分析行为或从数码相机数据中分析尺寸。本研究的最新成果总结如下：1.

We developed a system of digital camera attached in underwater video system for the study of morphometry in marine animals. Using this system, the sizes of marine animals are roughly estimated without catching animals by hand or fishing instruments. The unique point in this system is the attachment of digital camera in remote operating vehicle (ROV, Mitsui Zosen, RTV-100MKII). The video camera and digital camera in ROV connect to an operating systems and monitors settled on the ship. After taking pictures, the image data in MO in digital camera were easily transmitted to a personal computer from ROV on the boat. A resolution of recent digital camera rapidly improves in recognizing small marine animals, and our system of using digital camera is powerful technique for morphometry instead of using only under water video camera. The system is also used in understanding marine ecology by investigation integrated among taxonomy, morphometry, environmentology and environmental preservation for marine organisms. To the calculation of the size, a marketing software, "Composer" which is used for creating CG animation and beta cam video record system was prepared with beta cam video system, but finally we changed to a popular marketing software "Photoshop" for the analysis of behavior from video tape data or the size from digital camera data. Advanced results of this study are summarized as follows. 1. Digitalization of ROV 2. Development of transmission system of digital camera in ROV 3. Development of morphometry study in marine organisms 4. The promotion of digitization in under water video 5. The promotion of observation of environment in marine biology1. Digitalization of ROV 2.
