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.

为了进行海洋动物形态计量学的研究，我们研制了一套水下摄像系统。使用该系统，可以粗略估计海洋动物的大小，而无需用手或捕鱼工具捕捉动物。该系统的独特之处在于远程操作车（三菱商事，RTV-100 MKII）中的数码相机附件。船上的摄像机和数码相机连接到船上的操作系统和监视器上。拍摄后，数码相机中的MO中的图像数据可以很容易地从船上的摄像机传输到个人计算机中。近年来，数码相机的分辨率在识别小型海洋动物方面迅速提高，我们的系统使用数码相机代替仅使用水下摄像机是形态测量的强大技术。该系统还可用于通过对海洋生物的分类学、形态学、环境学和环境保护学的综合研究来了解海洋生态学。对于尺寸的计算，准备了用于创建CG动画和beta cam视频记录系统的营销软件“Composer”，但最后我们改为流行的营销软件“Photoshop”，用于从录像带数据或从数码相机数据分析行为的尺寸。本研究的最新结果总结如下。1. 2.数字化。2003年数码相机传输系统的发展。海洋生物形态计量学研究进展4.水下视频数字化的推广5.促进海洋生物学中的环境观测1。2.数字化。2003年数码相机传输系统的发展。海洋生物形态计量学研究进展4.水下视频数字化的推广5.促进海洋生物学环境观测
