Abstract (en)
[origin: WO03007244A1] The aim of the invention is to improve the reliability, especially in dynamic situations, of a method and a device for detecting the actual position of a person within a predetermined zone. The aim is attained by providing an image recording device (22) that monitors the predetermined zone (24). The recorded images are processed in an evaluation device (28) and when a person (14) is detected in the monitored zone, at least one feature (44, 46, 48) characteristic of the person (14) is determined. Further evaluation is then limited to said at least one characteristic feature (44, 46, 48) and an event signal (60) is generated if a relative modification of position of the at least one characteristic feature (44, 46, 48) beyond a predetermined minimum is detected.
