Method and Apparatus For Monitoring a Production Line
First Claim
1. Method for monitoring a production line (1), in which objects (5) are conveyed over conveyance paths (4) between machines (2, 3), comprising the following method steps:
- (a) generating a reference image sequence, such that it images at least one area of a conveyance path (4) to be monitored between machines (2, 3);
(b) determining a statistical characteristic variable derived from the movement of an object (5) conveyed between machines (2, 3);
(c) generating a test image sequence, which images the same area of a conveyance path (4) between the machines (2, 3);
(d) determining the statistical characteristic variable derived from the movement of an object (5) for at least one of the objects (5) imaged in the test image sequence;
(e) comparing the statistical characteristic variable determined for the test image sequence with the statistical characteristic variable determined for the reference image sequence.

Abstract
A method for monitoring a production line, in which objects are conveyed over conveyance paths between machines, whereby digital images of the production line are created, is characterized by the steps of (a) generating a reference image sequence, such that it images at least one area of a conveyance path to be monitored between machines, (b) determining the speed or acceleration of an object or a quantity derived therefrom for the reference image sequence, (c) generating a test image sequence, which images the same area of a conveyance path between the machines, (d) determining the speed or acceleration of an object or a quantity derived therefrom for the test image sequence, and (e) comparing the speed or acceleration determined for the test image sequence or a quantity derived therefrom with the corresponding quantity determined for the reference image sequence.
