Abstract
A vision-based automatic recovery method including steps of: generating a reference trajectory connecting an align point and a recovery point that is provided through wireless communication; taking an image containing a target through a front vision camera, determining a position and a size of the target in the taken image, and calculating a distance between the target and the unmanned aerial vehicle; generating an attitude command for changing a direction of the unmanned aerial vehicle so as to center the target in an image taken by the front vision camera; and generating a virtual trajectory by combining the generated reference trajectory and the generated attitude command, a weight of the attitude command being increased as the unmanned aerial vehicle moving from the align point to the recovery point.
