Abstract

A method for manufacturing control of machining of workpieces in a manufacturing hall that includes providing a plurality of image acquisition devices configured to acquire image sequences of allocated observation areas, identifying an object to be tracked in a first image of a first image sequence using at least one object feature, determining positions of the object feature in images of subsequent image sequences, determining a current position of the object by localizing the object feature in a temporally current image of one of the image sequences, and assigning the position of the object feature in the temporally current image to a current position in the observation area of the image sequence that includes the temporally current image, and integrating the determined current position of the object into the manufacturing control of the hall.
