MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202617028288 A) filed by Isra Vision Gmbh on March 10, 2026, for Method And Device For Inspecting A Reflective Surface.
Inventors include Arold, Oliver; and Kayal, Yaman.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: The invention relates to methods for inspecting a reflective surface (200) of an object arranged in a measurement chamber, with a device which has at least one 2- dimensional illumination pattern (201) for reflection on the reflective surface (200) and a plurality of cameras (203) for pixel-by-pixel recording of image information of the illumination pattern (201) reflected on the surface (200), wherein the position and orientation of the plurality of cameras (203) and of the at least one 2- dimensional illumination pattern (201) are known in a common coordinate system and the illumination pattern represents a temporally varying illumination pattern, wherein object image information is generated by applying a measuring sequence in which the cameras capture sections of the measurement chamber. The object image information is processed by means of the evaluation device, in such a way that output data is generated therefrom with regard to an object-related inspection task taking into account determined segmentation information, wherein the inspection task comprises, for example, the generation of defect information on the object and/or the calculation of surface normals for a plurality of points in at least one section of the reflective surface of the object and/or the calculation of the curvature for a plurality of points in at least one section of the reflective surface of the object, as output data. The invention further relates to a corresponding device, a calibration method and a computer program product.
