Abstract
In a method for ascertaining predistortion data () for a projection from a projector () onto a target surface () with known geometry data, a camera () is placed in a known relative pose (RKP) with respect to the projector and aligned toward the target surface (), the relative pose of the camera with respect to the target surface (RKZ) is ascertained from a camera image by means of machine vision, and the relative pose (RPZ) of the projector () with respect to the target surface () is ascertained herefrom and from the relative pose (RKP), and the predistortion data () are ascertained on the basis of the geometry data and of the relative pose (RPZ) of the projector () with respect to the target surface (). A projector module () contains a calculation unit () for performing the method, and the projector () and the camera (). The camera () of the projector module () or in the method is used for optically monitoring the interior (). An interior camera is used as the camera () of the projector module () or in the method.
