Abstract
A method for filtering distance information from a 3D-measurement camera system comprises comparing amplitude and/or distance information for pixels to adjacent pixels and averaging distance information for the pixels with the adjacent pixels when amplitude and/or distance information for the pixels is within a range of the amplitudes and/or distances for the adjacent pixels. In addition to that the range of distances may or may not be defined as a function depending on the amplitudes.
