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.
