Abstract

With Airborne Optical Sectioning (AOS), we have introduced a synthetic aperture imaging technique that captures an unstructured light field with camera drones. Optical images recorded within the shape of a wide (possibly hundreds to thousands of square meters) synthetic aperture area above forest are combined computationally to remove occluders, such as trees and other vegetation. The outcome is a widely occlusion free view of the forest ground and intermediate layers. AOS supports full 3D visualization but, in contrast to LiDAR, does not require depth reconstruction. It therefore makes real-time rates at low processing costs possible. Due to its wavelength-independence, a wide range of applications are enabled – including search and rescue, archaeology, early wildfire detection, surveillance, and wildlife observation. In this talk, I will report on the achievements and the challenges of the AOS project. Details: https://github.com/JKU-ICG/AOS/
