Abstract
A method for analyzing a three-dimensional (3D) information of an image based on a single camera according to an embodiment of the present disclosure is provided to. The method includes storing an image obtained by the single camera on a frame-by-frame basis, determining a plurality of feature points configuring a hand shape included in the stored image and extracting a region of interest (ROI) based on the feature points, tracking a change in a two-dimensional (2D) length component configured with feature points of the ROI during a predetermined time interval, analyzing a change in 3D coordinates of the feature points based on the change in the 2D length component and deriving a motion vector of the feature points during the predetermined time interval based on the analysis, and determining an operation indicated by a hand shape based on the derived motion vector.
