How to: Accurate iPhone 3D Scanning with Dot3D and Survey Control

Post by cahern3d »

It's great to see Rami Tamimi digging into Dot3D for some larger scale iPhone LiDAR scanning. This video covers the full processes of:

1. Scanning an entire large condo inside and out
2. Optimizing with the assistance of an extensive, accurate survey control target file (tied into geo-coordinates obtained outdoors)
3. Analyzing the resulting accuracy compared to control (1/100 ft!)
4. Working with Dot3D Edit for convenient desktop scan editing
5. Merging Dot3D data with drone data tied into the same control

He's really not using the best rendering settings for most of the video (somewhat choppy surface-based visualization). Pretty safe to assume the dense point clouds themselves are great from Dot3D.

The point cloud data shown in Pix4D at around the 12:40 mark may be more of what you're looking to see.
