摘要：A method for segmenting a projected pattern in an image recorded by a
camera includes recording, by a camera in a learning phase, a multiplicity of imagesproduced by virtue of a light source projecting the pattern from a plurality of differentangles onto a projection surface in a clean room, wherein the projection surface has aplurality of respectively different distances from the light source for each angle;transforming the multiplicity of images into a frequency domain representation;obtaining a value range of occurring frequencies from the frequency domainrepresentation of the multiplicity of images; and masking, in an application phase,frequencies other than the frequencies lying in the value range in a frequency domainrepresentation of the image recorded by the camera, wherein a difference image
produced in this manner is transformed back from the frequency domain representation.
