Abstract

The device (12) comprises generating means (120) configured to generate a binary descriptor associated with a given point in a current frame of a succession of video frames obtained by an apparatus such as an image sensor (10), said generating means comprising first means configured to determine a pattern of points pairs around said given point in the current frame, and comparison means configured to perform intensity comparison processing between the two points of each pair. Said apparatus (10) is likely to move in a rotation between the previous frame and the current frame, and said generating means further comprises processing means configured to process said pattern of points of said current frame with a tridimensional rotation information representative of said apparatus rotation between the previous frame and the current frame and obtained from inertial measurements provided by at least one inertial sensor (11).
