Within this paper, the problem of 3D inspection path planning for distributed infrastructure using aerial robots that are subject to time constraints is addressed. The proposed algorithm handles varying spatial properties of the infrastructure facilities, accounts for their different importance and exploration function and computes an overall inspection path of high inspection reward while respecting...
Unmanned aerial vehicles (UAVs) have gained special attention in recent years, among others in monitoring and inspection applications. In this paper, a less explored application field is proposed, railway inspection, where UAVs can be used to perform visual inspection tasks such as semaphore, catenary, or track inspection. We focus on lightweight UAVs, which can detect many events in railways (for...
This paper proposes an autonomous flight control method of quadrotor helicopter using only single Web camera. Recently, great attentions have been paid to the autonomous flight control method of quadrotor helicopter. In the previously proposed methods, for example, GPS, motion capture system and laser range finder are often applied to measure the position and posture of quadrotor helicopter. But,...
Insulator identification in aerial videos is one of the key procedures to the condition analysis for aerial power line inspections. This paper proposes a novel insulator recognition method for images taken by Unmanned Aerial Vehicles (UAVs) with highly cluttered background, which is to adopt a machine learning algorithm Support Vector Machine (SVM) as a classifier to distinguish insulator from the...
Micro aerial vehicles, such as multirotors, are particularly well suited for autonomous monitoring, inspection, and surveillance, e.g., for doing inventory in large warehouses. Key prerequisites for efficient MAV inventory missions is time- and energy-efficient flight. Generated trajectories must assure the visiting of certain waypoints while preventing large deviations or overshoot, as these can...
