Measurement Accuracy of 3D Reconstruction for Small Objects

3D reconstructions are widely used, the main challenge of them is the accuracy especially for small and detailed objects. Various software exists 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. The aim of the paper is analyzing the size accuracy of the reconstructed 3D models based on photogrammetry for small objects. Meshroom is used for 3D photogrammetry reconstruction and various software is used for measurement. Blender, meshmixer and blender and 3D slicer are used for measurement, all are free software. Experimental results show a high accuracy for objects sizes measured using meshmixer.
