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 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...
Heterogeneous CAD data exchange is very important in collaborative product development and also extremely difficult. Feature-based data exchange has many advantages than traditional geometry-based data exchange. According to the framework of procedure recovery in feature-based data exchange, this paper discusses the key issues of feature extraction and reconstruction, including the extraction of first-order...
Data exchange is one of key issues in collaborative design. The purpose of feature-based data exchange is that the target model is editable after being exchanged. This is the reason why nowadays feature-based data exchanges become the research focus beyond the traditional geometry-based data exchange. This paper presents a two-stage mechanism to recover a complete modeling process of a parametric...
Nowadays a lot of enterprises develop the products collaboratively using heterogeneous CAD systems. Feature based data exchange and interoperation among heterogeneous CAD systems are very important in pervasive computing environments. The key techniques in feature based data exchange are feature retrieval (extraction) and feature reuse (reconstruction). This paper presents a direct approach for feature...
