Abstract
A process for determining the position of closed holes in a component is provided. By carrying out laser triangulation measurements on an uncoated component and a coated component with holes, the exact position of the holes to be reopened may be detected following the coating. A device used to carry out this process is also provided.

A process for the surface analysis of at least partially closed holes in a component which are to be opened following coating, the process comprising:
- measuring the component comprising unclosed holes in the uncoated state and a mask model is generated which contains the position of the holes and also the orientation of the longitudinal axes thereof or the mask model is known in advance from a data record;
- carrying out a measurement by means of laser triangulation with the coated component and the at least partially closed holes wherein the data record thus generated represents the coating model;
- and
- comparing the mask model with the coating model in order to make it possible to detect the closed holes wherein the best possible concurrence of the mask model and the coating model is determined by iteration where the mask model is known in advance from the design of the component.
A device, comprising:
- a component
- a mount for the component;
- a measuring sensor;
- and
- a computation unit with a storage unit for mask models and coating models which iteratively determines the position and orientation of holes in the component.
