Optimal/suggested overlap
Posted: Wed Mar 13, 2024 5:08 pm
Hi, I am currently sending information to our processing team, on what overlap does C3D recommend. Do you have any recommendations?
Hi Howard,
I would happy to assist. While the optimal values for overlap (between successive images) and sidelap (between adjacent flightlines) are governed by photogrammetry principles, not Correlator3D.
For medium/large format cameras mounted on aircrafts, the overlap should be at least 60% of the image size. The recommended sidelap is 30%.
For small cameras mounted on drones, the recommended values for overlap/sidelap are 70%/50%.
let me know if you have any additional questions.
