Abstract
A device and a method are provided for detecting depth and color information of an object to be surveyed. A projection unit projects a predetermined wave pattern having first waves with at least one first wavelength in a spectral range outside visible light. A collector unit receives waves which have been at least partially reflected from the object and which include the first waves, that are processed by a first subunit of the collector unit, and second waves that are processed by a second subunit of the collector unit. The second waves have at least one second wavelength in the visible-light spectral range. The depth and color information of the object is detected on the basis of the waves.
