Co-operative study of comparative planetary geology using digital image information

在行星地质研究中，行星和卫星表面图像的数字数据是重要的线索，图像处理系统是必不可少的工具。在我们的项目中，我们可以增加数据读取/记录仪器并使用适当的软件，利用已有的个人电脑和工作站对数字数据进行图像处理。作为数据控制中心和我们的网络，我们在名古屋大学（现在在东宝专科大学）引进了一台数据库机器。这台机器现在不仅被我们的团队使用，也被日本更大的行星科学团体使用。在我们组，火星的火山活动历史、金星上的滑坡、金星上的熔岩流、金星上的构造、利用遗传算法开发图像处理方法、小行星的图像处理、小天体的形状和撞击、海洋数据库的应用、冰冻卫星上陨石坑的大小分布、金星-地球CD-ROM由我们组的成员完成。2005年10月94日，“行星地质学”研讨会在名古屋大学举行。我们大约有25名服务员。17年1月95日，本合作研究的总结研讨会在东京大学举行。

In the study of planetary geology, digital data of surface images of planets and satellites are the important clue and image processing systems are necessary instruments. In our project, adding data reader/recorder instruments and using appropriate softwares, we can utilize pre-existing personal computers and workstations for the image processing of digital data. As a center of data control and our network, we introduced a database machine at Nagoya Univ. (now at Toho Junior College). This machine is now used not only by our group but also by larger planetary science community in Japan.In our group, volcanic activity history of Mars, landslides on Venus, lava flows on Venus, tectonics on Venus, development of image processing method using genetic algorithm, image processing of asteroids, shape of small bodies and impacts, application of ocean data base, size distribution of craters on icy satellites, Venus-Earth CD-ROM were done by the member of this co-operative study.On 94-10-05, "Planetary Geology" workshop was held at Nagoya University. We had about 25 attendants. On 95-01-17, the summary workshop of the present co-operative study was held at the University of Tokyo.
