Comparative Analysis of 3D Models Made with Various Technologies on the Example of Altar in the Wang Temple in Karpacz

This article gives a scientific description and comparative analysis of 3D models of Wang Temple's altar in Karpacz. Two software's were used to create 3D models from photographs: Agisoft Photoscan and Context Capture. It was important to follow a few rules during obtaining photo data: keeping 60% coverage between two photographs, taking photographs parallel to each other and avoiding camera rotation. In order to create 3D models both software performs fallowing actions align photos/aerotriangulation, build dense point cloud, build mesh. The difference being the detailed algorithms and succession of operations. Point clouds from terrestrial Z+F laser scanner were used as a base, due to its decisively smaller coordinates error. Bentley Pointools software was used for comparing point clouds. Three aspects were taken into consideration: stretches, that occur at the edges of objects, the accuracy of point placement in the model and scale of the model.
