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化数据是重要线索，图像处理系统是必不可少的手段。在我们的项目中，通过增加数据读取器/记录器，并使用适当的软件，我们可以利用现有的个人计算机和工作站来进行数字数据的图像处理。作为数据控制中心和我们的网络，我们在名古屋大学引进了一台数据库机器。(现在在东湖初级学院学习)。这台机器现在不仅被我们的小组使用，而且还被日本更大的行星科学界使用。在我们的小组中，合作研究的成员完成了火星的火山活动史、金星上的山体滑坡、金星上的熔岩流、金星上的构造、使用遗传算法的图像处理方法的发展、小行星的图像处理、小行星的形状和撞击、海洋数据库的应用、结冰卫星上陨石坑的大小分布、金星-地球光盘。我们大约有25名服务员。2005年1月17日，本合作研究总结讲习班在东京大学举行。

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.
