3D optical measurement of mirrored surfaces involves irradiating surface with different statistical radiation patterns, detecting reflected radiation at different angles, evaluating radiation patterns according to similarity criterion
3D optical measurement of mirrored surfaces involves irradiating surface with different statistical radiation patterns, detecting reflected radiation at different angles, evaluating radiation patterns according to similarity criterion
The method involves irradiating the surface (1) with at least one elongated radiation source (2) using different statistical radiation patterns, detecting the reflected radiation with at least two flat detectors (4,5) at different angles and evaluating the time-varying statistical radiation patterns in accordance with a similarity criterion to determine corresponding points (7'-7''') between each detector and the source.. An independent claim is also included for a device for implementing the inventive method.
