Abstract:
Consumer-level remotely controlled smart drones are usually equipped with high resolution cameras, which make them possible to become unmanned "flying camera". For this purpose, in this paper, we propose an automatic view finding scheme which can autonomously navigate a drone to an proper space position where a photo with an optimal composition can be taken. In this scheme, an automatic aesthetic evaluation for image composition is introduced to navigate the flying drone. It is accomplished by applying commonly used composition guidelines on the image transmitted from the drone at current view. The evaluation result is then conversely used to control the flight and provide feedback for the drone to determine its next movement. In flight control, we adopt a downhill simplex strategy to search for the optimal position and viewing direction of the drone in its flying space. When the searching converges, the drone stops and take an optimal image at current position.
