| Outline of Research at the Start |
Various sensors from unmanned aerial vehicles will be unified to reconstruct large-scale outdoor dynamic 3D scenes in real-time.
(1)Compact RGB and depth cameras will be fused to incrementally reconstruct outdoor scenes in a coarse-to-fine strategy.
(2)NURBS surfaces will maintain the large-scale evolving 3D model while displacement mapping will generate detailed 3D geometry.
(3)Physical and semantic constraints in the scene will be used to enforce at all time a globally consistent 3D reconstruction with loops closed and minimal registration errors.

| Outline of Final Research Achievements |
The goal of this project was to develop a real-time system for 3D reconstruction of dynamic scenes with unmanned micro aerial vehicles.
We proposed a new method for robust and accurate fusion of depth images without increasing computational speed. We also proposed a method that can handle dynamic scenes like a moving person. This was achieved by jointly optimizing non rigid motion and geometry. To handle situations when depth information is not available, we proposed a solution for 3D shape estimation from a single RGB image. We focused on the case of the human body and proposed a new deep neural network to reconstruct detailed shapes of humans wearing loose clothes from single RGB images.
We proposed a new 3D scanning system equipped on a consumer-grade aerial drone that can capture live sequences of RGB-D data. our proposed system consists of a minicomputer powered by a portable battery and an RGB-D camera. We shared material and code and captured real world data with our system.
