Block Paving Herringbone - Photogrammetry based Environment Texture
Another capture I did, researching monopod's pros and cons for photogrammetry. This time I managed to capture 105 images.
With focal length set to 24mm, f/8 and average exposure time 1/60 sec I was able to stabilise camera good enough to get all images sharp and useful for further reconstruction.
This is my photogrammetry workflow I follow. (More details: https://www.artstation.com/artwork/K0PYG)
Source - Using monopod I managed to capture 105 images. With focal length set to 24mm, f/8 and average exposure time 1/60 sec I was able to stabilise camera good enough to get all images sharp and useful for further reconstruction.
Source - captured area - I covered roughly 2 square meters
Source - surface details
Color Calibration - Auto White Balance (camera's guess) vs Custom White Balance (reality). In this case I set Custom White Balance in the Camera before surface capture.
Reconstruction in Photoscan - based on 105 images I built 76mln poly model. As FBX struggles to keep vertex color information when mesh has over 67mln poly I trimmed needless sides to finally get 61mln.
Zbrush - building lowpoly for baking - to make seam removal easier and faster, lowpoly model was built and positioned to follow/match the pattern
