Paving Tarmac - Photogrammetry based Environment Texture
Another urban capture, this time tarmac paving. This is kind of tarmac commonly used for pavements in the UK.
I captured this one as a part of my 'monopod' experiment. It wasnt the best capture.
As you can see on the source preview, I angled the monopod the way to get all shot perpendicular to the surface, but as I was in hurry and moved fast as sun was coming from behind the cloud, my lens untwisted itself and changed the focal length during the capture. Fortunately it didn't affect reconstruction quality :)

My photogrammetry workflow I follow. (More details: https://www.artstation.com/artwork/K0PYG)
Source - using monopod I captured 37 images with focal length set to 35mm, f/10 and average exposure time 1/60 sec. Unfortunately my lens untwisted itself so the last few shots were taken with 35 -> 50mm :)

Photoscan preview. With 37 images I managed to get 65mln poly model. Cameras position are not as regular as they should be as I was in hurry due to sun coming. I also used just one marker.
