Abstract:
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 images produced by virtue of a light source projecting the pattern from a plurality of different angles onto a projection surface in a clean room, wherein the projection surface has a plurality 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 domain representation of the multiplicity of images; and masking, in an application phase, frequencies other than the frequencies lying in the value range in a frequency domain representation of the image recorded by the camera, wherein a difference image produced in this manner is transformed back from the frequency domain representation.

Claim (Index 1):
A method for segmenting a projected pattern in an image recorded by a camera, the method comprising:\n recording, by a camera in a learning phase, a multiplicity of images produced by virtue of a light source projecting the pattern from a plurality of different angles onto a projection surface in a clean room, wherein the projection surface has a plurality 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 domain representation of the multiplicity of images, and masking, in an application phase, frequencies other than the frequencies lying in the value range in a frequency domain representation of the image recorded by the camera, wherein a difference image produced in this manner is transformed back from the frequency domain representation.
