A remote operated selective target treatment system including a firing robot having a weapon and an optoelectronic sighting device, a central processing unit and a control screen displaying the prepared image of the target, and a control device. The central processing unit prepares the image intended for display, and includes an input module receiving digital images, an image analyzer receiving the image from the input module and detaching the target image from its environment, a modelling device modelling the contour of the image, a comparator connected to a library of silhouettes receiving the modelled image and checking it against the silhouettes, and an exclusion module receiving an image from the comparator and using a library of masks to apply a mask to the image and transmit the prepared image for display on screen.
