Overlap

To create an accurate 3D model, each point in the area of interest should be visible in multiple photos. A >66% overlap between consecutive photos is recommended. Each point in the area of interest should be visible by, at least, 3 cameras (min 10° offset). PhotoMesh can combine photos with different ground resolutions.

For structured aerial photography

§  Overlap in direction of flight (forward overlap) – 75 - 90% (recommended - 80%)

§  Overlap between neighboring rows (side overlap) – 70 - 90% (recommended - 80%)

Structured Aerial Photography Recommendations

The following guidelines are recommended for optimal model accuracy and texture quality:

§  Capture time – Avoid long shadows and sun reflections

§  Capture date – Capture all photos in the same season

§  Collection system – Use stable platforms with minimal smearing
