Abstract
A method for detecting an object inside a monitored zone includes monitoring at least a part of a monitored zone. Sensors generate respective single digital images of the total monitored zone, with the single images of all sensors being generated in a uniform coordinate system. Coordinate points of the single images are flagged as 'safe' by each sensor if they are free of the object, with all other coordinate points being flagged as 'unsafe'. The single images are each transmitted to an evaluation unit and are superimposed to form a resulting total image. The coordinate points of the total image, which are flagged as “safe”, correspond to those flagged as safe in at least one of the single images. All other coordinate points of the total image are flagged as unsafe. The coordinate points flagged as unsafe in the total image are used for the determination of the object coordinates.
