How is the 3D model created?

3D models are created using a technology called Photogrammetry. Roots of this science were layed out in the middle of 19. century. Long story short, this technology allows us to reconstruct a shape of an object based on multiple images.

To get the images we are using UAVs (drones) combined together with terrestrial photography using classic DSLRs.

After we get the images (i.e. a LOT of images) they are processed by a special photogrammetry software - we use Reality Capture now, but we used to use Agisoft Metashape before. Its not an easy task even for the most powerful machines and sometime takes a whole day of proccesing on 32 cores CPU

When we have the rough model, then a fine work begin. The model needs to be manually cleaned and decimated, as the generated one could easily exceed GBs of data. So in order to be displayd on a web, there is a lot of work to do to make it smaller.

Once we have our 3D model ready for the web, we need a cloud application that allows us to actualy share it on the web. 3D models on 3DCesko are hosted on www.kroscloud.com

Kroscloud also allows you to embedd panoramic photos into your 3D model, add captions and points of interest and most importantly, it also allows you to switch between different time periods of the scenery.
