Adaptive View Planning for Aerial 3D Reconstruction

With the proliferation of small aerial vehicles, acquiring close up imagery for high-quality reconstruction is gaining importance.We present an adaptive view planning method to collect such images in an automated fashion. We first start by sampling a small set of views to
build a coarse proxy to the scene. We then present (i)~a method that builds a set of adaptive viewing planes for efficient view selection
and (ii)~an algorithm to plan a trajectory that guarantees high reconstruction quality which does not deviates too much from the optimal one.
The vehicle then follows the trajectory to cover the scene, and the procedure is repeated until reconstruction quality converges or a desired level of quality is achieved.
The set of viewing planes provides an effective compromise between using the entire 3D free space and using a single view hemisphere to select the views.
We compare our algorithm to existing methods in three challenging scenes. Our algorithm generates views which produce the least reconstruction error comparing to three different baseline approaches.
