AB  - Trends of the optical three dimensional measurements are, nowadays, regarding to the high accuracy, small price, real-time processing and equipment portability. In connection with the improvement of old methods and appearance of new one, there is a strong need to compare them for finding the best solving a specific task. The master thesis includes implementation, recommendations and optimal settings, current optical three dimensional measuring methods such as laser tracker measurements and laser, photo-based and handheld scanning for the geometric inspection of production parts in shipbuilding. The main objective is to find out if the accuracy of 3D mesurments with laser scanning with Z+F Imager 5016 and Laser Control software, industrial photogrammetry with Nikon D2Xs camera with the Agisoft PhotoScan software and handheld scanner DPI-7 is enough for the final measurements of the adhesive angle of the ship. The estimate of the metrological and evaluation efforts of each method is also important. The measurements were made in one of the halls of Ostseestaal company in Stralsund, Germany with a help of co-fellows geodesists and instruments from Engineer Team Nord company (ITN) and Neubrandenburg and Bochum Universities of Applied Sciences. The comparison of the mesh models in 3dReshaper, based on the point clouds calculated in Laser Control, Agisoft PhotoScan and Phi.3D softwares and the data from laser tracker Leica AT960LR as ideal geometric description of the detail should be analyzed. Time and cost estimates for the four optical surveying methods will be presented.
