CALIBRATION TEMPLATE AND CALIBRATION METHOD FOR GEOMETRIC CALIBRATION OF A PLURALITY OF CAMERAS OF A CAMERA ARRAY

摘要

The invention relates to a calibration template (1) and a calibration method for geometrically calibrating a large number of cameras (8.1) with entocentric lenses (8.2) in a camera array (8), in particular in optical inspection devices for automatically checking objects It is proposed to propose a device and a method for calibrating a plurality of cameras (8.1) arranged in a camera array (8) with entocentric lenses (8.2), in which the calibration can be carried out independently of features of a real test object and on more than one level is. According to the invention, the object is achieved by a calibration template (1) for geometrically calibrating a large number of cameras (8.1) with entocentric lenses (8.2). The calibration template (1) contains a carrier plate (2) with a flat surface (3) on which a two-dimensional structure (4) and point-defining objects (5) are distributed. Each of the point-defining objects (5) has a local environment (5.1). In the local environment (5.1), the two-dimensional structure (4) has a characteristic pattern that is designed differently for each point-defining object (5).
