Patent ID: 11754439

Abstract:
The invention relates to a method for photometrical charting of a reflectance standard (Z) illuminated by a license plate light (1). A camera (4) releasable by a control unit (5) is arranged and aligned relative to a holding device (3) configured for holding a reflectance standard (Z) in such a way, that a luminance density image (B1, B2) recorded by the camera (4) at least covers the reflective surface (Z.1) of a reflectance standard (Z) held by the holding device (3). A license plate light (1) is arranged in a positioning device (2) which is movable by the control unit (5). The positioning device (2) is controlled by the control unit (5) in such a way that the license plate light (1) arranged therein is traversed to at least one position (P1, P2), optionally to multiple positions (P1, P2) sequentially, relative to the reflectance standard (Z) arranged in the holding device (3) and held there. In each position (P1, P2), recording of at least one luminance density image (B1, B2) is triggered. An overall image (B) is formed from the recorded luminance density images (B1, B2) recorded by the camera (4). Furthermore, the invention relates to an arrangement for performing this method.
