APPARATUS AND METHOD FOR DETERMINING A MEASUREMENT VARIABLE ON A MEASUREMENT OBJECT

摘要

An apparatus (10) for determining a measurement variable has a measuring table (30) for arranging a measurement object (32), a base (12) on which the measuring table (30) is supported via a multiplicity of bearing points (34), and a first sensor device (20, 22) which is designed to identify a number of measurement points on the measurement object (32). A second sensor device (50) is designed to determine a multiplicity of individual bearing loads. Each individual bearing load represents the mechanical load on a bearing point (34) caused by the measuring table (30) and the measurement object (32). An evaluation unit (38) is used to determine the measurement variable on the basis of the identified measurement points. According to one aspect of the invention, the evaluation unit (38) is designed to use the individual bearing loads to determine a spatial position (36) which represents a position of the centre of gravity of the measuring table (30) with the measurement object (32) relative to the bearing points (34).
