Abstract
The disclosure relates to a method for calibrating and/or evaluating a light propagation time camera by means of a reference surface, wherein the light propagation time camera has a light propagation time sensor consisting of an array of light propagation time pixels, in which method various spacings between the light propagation time camera and the reference surface are set in order to calibrate and/or evaluate the light propagation time camera by means of translational spacing changes. The method has the following steps: determining first distance data for a first spacing, determining second distance data for a second spacing, calculating distance differences from the first and second distance data, determining an orientation of the light propagation time camera with respect to the reference surface on the basis of the calculated distance differences.
