Abstract

In this paper, we propose a novel model-based coverage path planner for the 3D reconstruction of a target structure with an unmanned aerial vehicle (UAV). The proposed method rapidly calculates initial viewpoints considering the ground sampling distance (GSD) by partitioning a structure by height. Then, optimal viewpoints are selected by checking the collision and calculating overlaps and coverage. Next, the newly developed collision-aware Traveling Salesman Problem (CTSP) is used to connect the optimal viewpoints while guaranteeing the shortest distance and obstacle avoidance. Finally, the resulting path is refined as a control-efficient trajectory that considers the dynamics of UAVs. The performance of the proposed algorithm is verified by experiments on diverse structures.
