Methods for assisting in the localization of targets and observation devices enabling implementation of such methods

摘要

The present invention relates to a method for assisting in the localization of a target (24) for a first user equipped with a viewing device (26) comprising augmented reality observation means (11) associated with a frame of reference of the first user. According to the method, a reference platform 1 connected with a main reference frame RM is located in a region, the reference platform is observed from at least one camera 13 worn by a first user, and the observed platform ( The geometry of 1) is compared to its numerical model, and the orientation and position of the first user frame of reference RU1 is derived with respect to the main frame of reference RM. It is thus possible to display, on the augmented reality observation means 11 , at least one virtual reticle for detecting the position of the target 24 .
