Abstract
The three-dimensional real structure of a component can be captured by means of best fit by simply recording two-dimensional images and comparing a known three-dimensional model. A component is placed on a measurement stage having reference marks and is photographed several times in two-dimensions. The photo recordings are compared with a three-dimensional model of the component. A three-dimensional model is produced using best fit of the two-dimensional recordings and the stored model.
Claims21
A three-dimensional surface inspection system, comprising:
- a measurement stage on which a component is placed for three-dimensional capturing;
- and the system has at least one reference mark for reference to the component and a position of the component at the measurement stage;
- a camera system at various selected locations, the camera system comprising a respective camera at least at 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;
- and
- a computer with a memory programmed with a three-dimensional model of the component, the computer memory is further programmed and operable to receive the two-dimensional recordings and to compare the two-dimensional recordings of the component by the camera system to the stored three-dimensional model, and to produce a three-dimensional model of the component to be measured using best fit of the two-dimensional recordings and the stored three-dimensional model.
