Drone Navigation Made Easier by Computer Graphics Researchers
Bedrich Benes, a professor of computer graphics technology, and doctoral student Hao Kang collaborated with corporate researchers to develop a touch-screen method to navigate and take pictures with drones.
The method, called FlyCam, works with the concept of combining the drone and the camera movements.
“So the user doesn’t have to think about multiple controls for the drone and the camera,” Benes said. “He or she can think about the drone as a simple three-dimensional flying camera that is being controlled by simple gestures on a touch-screen device.”
FlyCam uses one- and two-finger drags across a smartphone or tablet to control the drone as it accelerates or turns and takes images. The drone moves forward or backward along the camera’s axis with single or double taps to the screen.
Traditional, more complicated drone controls utilize dual joysticks for the drone navigation as well as an additional joystick and gimbal – a pivoted support that allows rotation on a single axis – to control the camera.
As part of the research, Benes said they looked at the ability of licensed drone pilots with a remote control and compared that to people who have picked up a drone for the first time using FlyCam.
FlyCam was testing using an Android system. Fliers worked better when using a tablet, which allowed for larger movements and better control. Benes said that he and Kang will continue working with on the research, which will include automated photos from the camera.
