Abstract

1533935 Tracking device LICENTIA PATENT VERWALTUNGS GmbH 19 Jan 1976 [21 Jan 1975] 2012/76 Heading H4D A tracking device is stated to comprise an observation device for producing signals B(x) containing information re. the x, y position of a target within a scanned field; at least two imageevaluating devices 2-7 each arranged to receive signals from the observation device, to evaluate the signals according to predetermined criteria and to transmit evaluating signals indicating the deviation of the target from the centre of the scanned field to an evaluation unit 8. Determining therefrom the most probable position of the target and producing adjusting signals based on the determination; and a drive for varying the directional position of the observation device in dependence on the adjusting signals coarse but fast signals may be combined with to complement fine but slow signals from various ones of the devices. The criteria used by devices 2-7 may be contrast, local filtering, correlation, contour, movement and background. An image store 10 may record a view of the target at the beginning of the tracking process.
