Document Type and Number:
WIPO Patent Application WO/2018/049643
Kind Code:
A1
Abstract:
Systems and methods are used to operate a movable object to avoid obstacles. A plurality of image frames are acquired. The plurality of images are captured within a predefined time window by an imaging device borne by the movable object moving along a navigation path. One or more objects adjacent the movable object are identified by measuring pixel movements within the plurality of image frames. Movements of the one or more objects relative to the movable object are estimated using dimensional variations of the one or more objects within the plurality of image frames. The navigation path of the movable object is adjusted in accordance with the estimated movements of the one or more objects.
