The bridge was reconstructed from 500 Pics in RealityCapture. Original mesh was decimated from 350 mio. faces to 1,5 mio. to fulfill Sketchfab requirements - the simplification tool in RC works quiet well as it preserves many details in the Model.16k texture from RC was added. The inner ceiling of the bridge was the only part where Agisoft Photoscan did a better job - RC seems to have some problems here (needs more pics and higher overlap).
Cameras: Sony Alpha 6500 & DJI Phantom 4 Pro (20MP).
