METHOD FOR OBJECT MARKING USING A THREE-DIMENSIONAL SURFACE INSPECTION SYSTEM USING TWO-DIMENSIONAL RECORDINGS AND METHOD

摘要

Method for object marking using a three-dimensional surface inspection system using two-dimensional recordings and method by simple recording of two-dimensional images of a component and comparing the images with a known three-dimensional model for enabling the three-dimensional real structure of a component to be captured using best fit. Photographing measuring points in a measuring point pattern and orienting the component with reference to markers at the points enables orienting the two-dimensional images with the three-dimensional model.

1. A system for object marking comprising, a three-dimensional surface inspection system (1), comprising:
a measurement stage, on which a component is placed for three-dimensional capturing, and the system has at least a reference mark for reference to the component and its position at the measurement stage; a camera system at various selected locations, the camera system comprising a respective camera at least some of the locations and/or a camera positionable at least at some of the locations, and the cameras and/or camera of the camera system are configured and oriented to take two-dimensional recordings of the component; a computer programmed in a non-transitory medium and operable to receive the recordings and to compare the two-dimensional recordings of the component by the camera system to a stored three-dimensional model, and a three-dimensional model of the component to be measured is produced using best fit of the two-dimensional recordings and the stored three-dimensional model; and at least one projector configured and operable to receive information from the computer and to generate markings or a measurement point pattern on the component based on the three-dimensional model of the component.
