1. A method for checking workpieces including vehicle bodies, the method comprising:
determining one or more workpiece parameters of the workpieces to be checked and/or one or more facility parameters of a treatment facility for treating the workpieces to be checked, wherein one or more of the following parameters are provided as workpiece parameters:
workpiece temperature measured locally;
areally measured and/or averaged workpiece temperature or workpiece temperature distribution;
local speed, measured in particular by a sensor in the form of an anemometer, in particular flow speed of the air at and/or around the workpiece;
measured reflection properties of a workpiece surface;
measured absorption properties of a workpiece surface;
measured emission properties of a workpiece surface;
determined local workpiece temperature on the basis of a simulation;
temperature distribution on the workpiece, determined on the basis of a simulation;
information about the nature and/or type of the particular workpiece;
information about physical and/or production-related workpiece characteristics;
an individual workpiece identification number;
information about a manufacture and/or processing of the particular workpiece preceding the treatment; or
information about a post-treatment and/or further processing of the particular workpiece following the treatment; and
at least one of processing or compiling the one or more workpiece parameters and/or the one or more facility parameters, wherein a workpiece-specific data set is created for each workpiece.
