[3D Models] How important are obliques?

[Hammer Missions]

Anyone capturing building 3D models?

Do you capture oblique photos to get better results? If so what high and low oblique angles do you use?

We have been running some of our experiments on an old building and the difference between using obliques vs not using obliques is night and day!

The Importance of Oblique Images in 3D Drone Mapping

Overview It's important when it comes to photogrammetry and 3D Modelling that you understand what the terms and abbreviations are and what they are used for. In this post, we will be looking at two very common terms and why using them together is very important to create the best 3D Model...

I agree with you! When I create 3D models of buildings and structures as a hobby, I find that using oblique angles is very important. Without them, my models end up missing important details and the photos don't look as good.

15° above (forward of) nadir is what we always use. This translates to 75° below horizon. Different software uses different orientation for 0°. For some, 0° is camera facing strait down (nadir) and for others 0° is camera facing straight ahead.

Would it be fair to say that there is a correlation between the height of the buildings being captured and the level of oblique angle used?
