Method used for working process of printing technique controlling machine

Abstract

A method for controlling an operating process of a printing machine uses parameters of 3-D scenes taken with only one camera. A learning phase is performed in which the object in a non-moving state and its surroundings are illuminated from different directions by different fixed-location light sources, one after another. For each illumination scene, image signals reproducing the object and its surroundings are obtained with the image recording device. The image signals are processed and an unambiguous association between object edges and object shadows in relation to a light source in each case are determined and stored. In an operating phase, the moving object and its surroundings are illuminated simultaneously by a plurality of light sources, and, from the data stored in the learning phase and the image signals obtained continuously in the operating phase, the position of the object in space is determined.

Description

technical field

[0001] The invention relates to a method for controlling the working process of a machine in printing technology, in which method position signals of a moving object are obtained with an image-capturing device, in which method these position signals are processed as desired affect the work process.

[0002] The invention enables the automation of paper processing machines, in which the determined state parameters, which are present as 3D scenes, are detected using cameras and image processing devices. The detection of status parameters can be carried out through the vision of the machine operator. Here, the human visual system aids this detection with its spatial perception capabilities, in particular through stereoscopic viewing. The machine operator can successively assume different positions with his head in order to obtain a comprehensive 3D impression. Background technique
