A method for coordinating a target point between remote image sensors of sensor modules operated by different operators, wherein each image sensor is imaging a mutual area of interest at a different imaging perspective, wherein the image sensors comprise a first image sensor of a first sensor module operated by a first operator, and a second image sensor of a second sensor module operated by a second operator, the second sensor module situated at a separate location from the first sensor module and communicatively coupled therewith by a data communication channel, the method comprising the procedures of: designating at least one target point on a first image of an area of interest acquired via said first image sensor at a first imaging perspective; defining and characterizing a plurality of feature points on said first image within a region in the vicinity of the designated target point; transmitting signatures of the defined feature points from said first sensor module to said second sensor module, over said data communication link; and identifying said target point in at least a second image of said area of interest acquired by said second image sensor at a second imaging perspective, by implementing an iterative convergence operation towards the target point location in said second image, wherein said iterative convergence operation comprises: in a first iteration, locating in said second image feature points corresponding to the feature points defined in said first image and thereby identifying a cluster of feature points delimiting a subregion of said second image; in each subsequent iteration, selecting a subset of feature points of said first image relative to the previous iteration by reducing, in the first image, the size of the region in the vicinity of the designated target point and locating, in the subregion of the previous iteration of said second image, feature points corresponding to the subset of feature points defined in said first image, wherein said subregion is defined by the cluster of feature points located in the previous iteration; and when a termination condition is reached, establishing the subregion defined by the remaining cluster of located feature points in said second image to represent said target point, wherein said procedure of defining and characterizing a plurality of feature points comprises establishing a respective signature for each feature point, and wherein locating corresponding feature points comprises comparing the signatures of the respective points and selecting the point with the closest signature. designating at least one target point on a first image of an area of interest acquired via said first image sensor at a first imaging perspective;
