Abstract
A system, installed in the extension of a line across which an object or a person passes, includes: an optical device for projecting an image of this line onto a photosensitive sensor capable of providing an image signal; at least a processor for processing the image signal; and a screen, connected to the processor, for displaying an image representative of the image signal, called the video image, connected to said processor, wherein the sensor is formed of a pixel matrix. A reticule signal is generated and superposed onto the video image displayed on the screen, the system also being capable of generating electric signals originating from a pixel column which corresponds to the position of the reticule on the screen.
