Method for detecting curved or straight sections with hollow space surfaces, wherein a raster is associated to the hollow space in its desired state and a normal vector is affected to each selected point of the raster. A ruled surface is then set by the center of a theodolite-type measuring apparatus, and for each normal vector. The aiming points are controlled by means of a measuring apparatus of the laser radar type and, in case of registration of those points with the normal vector, the space direction is registered in the raster system and the spatial coordinates of the aiming point are compared with the theoretical coordinates of the corresponding point of the raster. |
