Completeness checking of constructional steel structures with several hundred mounted parts (such as car body shells/chassis for rail vehicles, for example) represents a great challenge. Based on the results of this study, that task can now be presented as instrument-based testing with a largely automated test report. For this purpose, the actual state is captured by a 3D scanner, with the subsequent evaluation being performed by an algorithm developed during this study. The use of 3D scanners allows to obtain sufficiently comprehensive information about the actual configuration (as-is state) of the constructional steel structure to be checked. By using an adapted and newly developed algorithm, the respective 3D model as the target state is superimposed over the actual state, which results in difference figures. These difference figures show possible deviations and missing parts, at least, however, suspect points to be then checked again manually. Thus, the disadvantages of the exclusively manual completeness checking practiced so far, i.e. tiredness and slowness of the inspectors, can largely be avoided.
