| Outline of Final Research Achievements |
This study intends to develop a ball-type unmanned aerial vehicle (UAV) deploying a CMOS camera over two years. The study covers examination of maneuvering performance of the UAV, image processing from the CMOS camera and optimal ways of data transmission. Prototypes of the ball-type UAV have been successfully built. However problems to be solved have been observed through the test flights. The typical problem was on flight stability, which would be a great concern for real-word applications. Another problem was lack of strength of the frame that protect hovering system inside the frame. GFRP frame, thus, has been molded to enhance the from strength by sacrificing the weight saving. For the image processing, the image from the CMOS camera would provide valuable information such as cracks with the help of the technique called Super-resolution. It is noteworthy that findings from the image processing would be applied for mobile robot inspection.
