Abstract
A method, apparatus, and computer program product for monocular obstacle detection on a drone flight path. A drone is instructed to move forward at a constant horizontal speed and concurrently perform a planned motion in at least one perpendicular direction. A monocular camera mounted on the drone is operated to capture one or more image pairs comprising at least a first frame captured along the flight path and a second frame captured at a deviation from the flight path effected by the planned motion. The first and second frames are analyzed to determine stereo matching and according thereto estimate a motion vector between the first and second frames for at least one region of interest. In response to determining according to the motion vector that an obstacle is present on the flight path, at least one obstacle detection response pattern is applied.
