LED Panel Detection and Pattern Discrimination Using UAV’s On-Board Camera for Autoflight Control

[abstFig src='/00280003/04.jpg' width=""250"" text='UAV autoflight control system using LED panels' ] The UAV flight control method we propose uses LED panels and a video camera on the UAV. Specifically, the LED panel displays patterns related to the UAV commands and blinking patterns for panel detection. A panel detection process based in UAV video camera images uses the frequency of green blinking as a cue for panel detection, then command patterns are distinguished and the UAV performs tasks based on this pattern (command). In experiments we performed for panel detection and discrimination using the UAV, we confirm the effectiveness of the proposed method for autoflight control.
