Abstract: A method includes identifying an object in a disparity map to be tracked by a movable platform, determining positions of a plurality of elements representing the object in a first image frame captured by an imaging device carried by the movable platform, selecting one or more characteristic points of the plurality of elements representing the object as tracking points of the object in the first image frame, and updating, according to an updated disparity map and a current location of the movable platform, locations of the tracking points of the object in a second image frame captured by the imaging device.

Abstract: A method includes obtaining a disparity map based on stereoscopic image frames captured by stereoscopic cameras borne on a movable platform, determining a plurality of continuous regions in the disparity map that each includes a plurality of elements having disparity values within a predefined range, identifying a continuous sub-region including one or more elements having a highest disparity value among the elements within each continuous region as an object, and determining a distance between the object and the movable platform using at least the highest disparity value.
