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
