Task:
360° digitisation of the housing half of a low pressure steam engine (Siemens AG / Muehlheim) with the terrestric laser scanner Surphaser model 100HSX-SR.
For the proof of dimensional stability against the CAD model it is necessary to scan the inside as complete as possible and to scan the outside at relevant areas. A sufficient coverage is achieved with a total of 7 scans: One front scan (Figure 1, pos. 3), two scans from underneath and 4 horizontal scans at the corner positions (pos. 4-7). |

10 contrast targets are distributed in the scan volume for the referenzing of the scans against each other. Figure 3 (animation) shows the outside scan images with the automatically extracted target positions. The scans are automatically referenced in the post processing software. |
