概要
Toshiba Corporation is constructing a database system of as-built data of equipments and components in various n uclear plants in order to reduce the amount of redesign works when the plants are modified. We are obtaining the as-built data by using 3D laser scanner, and storing the data as 3DCAD models for ease-of-use. However, it takes long hours to obtain 3DCAD models because the volume of 3D laser scan data is very large and workers manually c onvert those data to 3DCAD models.In this development, we have constructed a prototype system to automatically g enerate 3DCAD model of plant components from 3D laser scan data. This report shows the outline of our method to automatically recognize the size and the installation position of plant components from point-cloud data and con vert to 3DCAD models. This report also shows the applicability of this system based on some experimental results.
