METHOD FOR THE SPATIAL CHARACTERISATION OF THE OPTICAL EMISSION BEHAVIOUR OF LIGHT AND RADIATION SOURCES

摘要

The present disclosure relates to a method for photometrical charting of a light source (Q, 3) clamped within a positioning device (1) and stationary relative to an object coordinate system (T) by means of a luminance density measurement camera (4) arranged stationary relative to a world coordinate system (W), wherein the light source (Q, 3) is moved between a first actual measurement position (P1′) and at least one further actual measurement position (P2′ to P5′) along a kinematic chain of the positioning device (1) within the world coordinate system (W), wherein a luminance density measurement image (81 to 85) describing the spatial distribution of a photometric characteristic within a measurement surface is recorded by means of the luminance density measurement camera (4) in each actual measurement position (P1′ to P5′) with the light source (Q, 3) turned on, and wherein the position and/or orientation of the object coordinate system (T) relative to the world coordinate system (W) is recorded in each actual measurement position (P1′ to P5′) in direct reference to the world coordinate system (W) without reference to the kinematic chain of the positioning device (1). Moreover, the present disclosure relates to the use of such a method for photometric charting of a headlight (3).
