Method Of Determining A Direction Of An Object On The Basis Of An Image Of The Object
Abstract: The invention relates to a method of determining the absolute direction of an object of a scene (1) with a predetermined desired performance. It comprises a learning phase and an on line operation phase the learning phase comprising the following steps: acquisition by circular scanning by means of a first optronic imaging device of determined fixed position of a series of partially overlapping optronic images (2) including an image or several images of the scene (step A1) automatic extraction from the images of descriptors defined by their image coordinates and their radiometric characteristics with at least one descriptor of unknown direction in each overlap (21) of images (step B1) on the basis of the descriptors extracted from the overlaps between images automatic estimation of the relative rotation of the images and mapping of the descriptors extracted from the overlaps (step C1) identification in the images of at least one known geographical reference direction (22) of precision compatible with the desired performance and determination of the image coordinates of each reference (step D1) on the basis of the descriptors extracted from the overlaps and mapped of the direction and image coordinates of each reference automatic estimation of the attitude of each image termed the fine registration step (step E1) on the basis of the attitude of each image of the position and of internal parameters of the first imaging device and of the image coordinates of each descriptor calculation of the absolute directions of the descriptors according to a predetermined model of picture capture of the imaging device (step F1) the on line operation phase comprising the following steps: acquisition of at least one image of the object termed current image (20) on the basis of a second imaging device of determined fixed position (step A2) extraction of the descriptors from each current image (step B2) mapping of the descriptors of each current image with the descriptors whose absolute direction was calculated during the learning phase so as to determine the absolute direction of the descriptors of each current image (step C2) on the basis of the absolute directions of the descriptors of each current image estimation of the attitude of each current image (step D2) on the basis of the image coordinates of the object in each current image of the attitude of each current image of the position and of predetermined internal parameters of the second imaging device calculation of the absolute direction of the object according to a predetermined model of picture capture of each current image (step E2).
