Abstract: Method for collaborative observation between a local targeting device and a distant targeting device located at different geographical positions and able to acquire images. The method including: when it is implemented by the local targeting device, execution of a procedure for determining a position of an observed object, referred to as the local targeted object, including application of a method for matching points of interest, determined on a local image by the local targeting device, representing a distant image obtained from the distant targeting device. If matching is successful, the local targeting device determines the position of the local targeted object according to information representing a position of a distant targeted object supplied by the distant targeting device and a transformation law allowing to pair the distant and local points of interest obtained when said matching method is applied and controls display of an image comprising the local targeted object.

Abstract: Method for collaborative observation between a local targeting device and a distant targeting device located at different geographical positions and able to acquire images, respectively referred to as local images and distant images, the method comprising, when it is implemented by the local targeting device, an execution of a procedure for determining a position of an observed object, referred to as the local targeted object, comprising an application (403) of a method for matching points of interest representing a distant image obtained (400, 401) from the distant targeting device with points of interest (402) determined on a local image by the local targeting device.
