Small scale quad-rotor unmanned aerial vehicle (UAV) has attracted much attention in recent years and has been widely adopted in many civil applications, e.g. inspection of critical infrastructure spanning over a large geographical area. In a typical UAV based inspection system for large-scale photovoltaic farm, it is required to control the mounted gimbal camera taking pictures of all the PV modules...
With the rapid development of solar photovoltaic power generation, inspection for PV plants based on UAV platforms has become prevalent. Despite the obvious advantages in efficiency, cost, accuracy and so forth, a new challenge should be noticed that how to match PV strings between images correctly in UAV images' processing when detecting the failures in solar panels or inspecting installed capacity...
The asset assessment and condition monitoring of large-scale photovoltaic (PV) systems spanning over a large geographical area has imposed urgent challenges and demands for novel and efficient inspection paradigm. In this study, an automatic UAV-based inspection system is presented and implemented for asset assessment and defect detection for large-scale PV systems. Two typical visible defects of...
The unmanned aerial vehicles (UAVs) have been considered an efficient platform for monitoring critical infrastructures spanning over a large geographical area. In this paper, a novel UAV optimal path planning approach based on the combination of A∗ search algorithm (AS) and ant colony optimization (ACO) algorithm for UAV patrolling is presented. The proposed path planning solution aims to identify...
The growing interest in the application of unmanned aerial vehicles (UAV) in civil applications has been observed in recent decades. The UAV can be considered as a hardware platform for patrolling the critical infrastructures by carrying camera devices. Such UAV based patrolling system can significantly improve the efficiency of system monitoring and fault detections, e.g. prognosis and diagnosis...
