ABSTRACT:
Apparatus (10) for identifying the position of a body (21) in a scene (20) comprises a first station (11) incorporating a raster-scan imaging device (15) having a field of view (19) with azimuthal and elevational rotational freedom and variable magnification the settings of which are respectively sensed by sensors (24,25,26). A signal processor (16) collects the video signal from device (15) and the sensor signals and adds the latter to part of the raster scan which, in playback, does not obscure the video picture generated by the video signal. The processor (16) is connected by lead (28) to a second station (12) which incorporates a raster-scan playback device (32) associated with an operator-actuated electronic cursor generator (33). The cursor position as selected by the operator to designate the body (21) on the image of the scene (20) is identified by a signalling circuit (36) and fed to a computer (38) which also receives the sensor signals extracted from the processor (16) output by an extraction circuit (31). The computer (38) functions according to a predetermined algorithm to provide a read-out on device (39) of the position of the body (21).
