  • Publication number: 20240420318
    Abstract: A measuring system for measuring an object, the measuring system comprising a capture device comprising a set of illumination elements for illuminating the object and a set of cameras for capturing an image of the object, and a controlling and processing unit. The controlling and processing unit comprises at least a data acquisition functionality which is configured to provide surface data by activating at least a part of the set of illumination elements for illuminating the object with measuring light and capturing at least one image by detecting measuring light reflected at the object by means of at least a part of the set of cameras.

  • Publication number: 20240415444
    Abstract: A method for identifying a surface property of the skin of a person, the method comprises acquiring surface data of the skin of the person by activating illumination elements for illuminating the skin of the person with measuring light and capturing at least one image by detecting measuring light reflected by the skin of the person by means of a camera, and providing a 3D model of the skin of the person by processing the surface data. The 3D model is provided in a virtual space and a virtual light source is provided in the virtual space to virtually illuminate the 3D model with illumination light, wherein illumination parameters of the virtual light source are variable.

  • Patent number: 12048555
    Abstract: A capture device for imaging a person, in particular the face or a part of the face of the person, the capture device comprises at least one camera for capturing an image of the person. The capture device comprises an infinity mirror comprising at least two mirror surfaces arranged oppositely from each other, a light source for emitting light, and a front side to look inside the infinity mirror. The infinity mirror is arranged at the capture device and placed and oriented relative to the capture device so that a capture range with an insight axis and an insight distance for the person is defined and defined capturing of the person by means of the at least one camera is provided when the person is positioned according to the capture range.

  • Patent number: 11612468
    Abstract: The invention relates to a polymerization and post-tempering device (10) for tempering, in particular post-tempering, dental restoration parts (54) made of polymerizable plastics. At least one light source (38) which emits light in the visible and/or ultraviolet wavelength range and a light chamber with a door (14) to the light chamber are provided. The door (14) comprises a window (20) with a window pane (22) which consists of at least two layers (56, 58) whose layer facing the light chamber reflects at least 90%, in particular approximately 95%, of light, and whose layer facing away from the light chamber filters out UV light and/or blue light.
