3D reconstructions are widely used, the main challenge of them is the accuracy for small and detailed objects. Various software exist for 3D reconstruction, free and paid ones with various performances. In this paper the performance of 3D object reconstruction will be evaluated in terms of size accuracy regarding number of source photos. The aim of the paper is analysing the size accuracy of the reconstructed 3D models based on photogrammetry for small objects by configuring pipeline in Meshroom. Meshroom is used for 3D photogrammetry reconstruction and MeshLab is used for measurement, both are free software. Experimental results show a high accuracy for objects sizes. Although the tests are done for small objects, the results are promising for cloning body parts used for prosthetics.
