Kurzbeschreibung (Abstract)

In this thesis, a spectral reflectance estimation using Wiener filter is presented. The spectral reflectance was reconstructed with RGB values of the SLR digital camera under 6 LED channels. On purpose of composing Wiener filter, the camera sensitivity was obtained from measuring of monochromatic light together with spectroradiometer and monochromator. A simulation regards to spectrum reconstruction was operated to test the performance of Wiener filter in ideal condition. An actual spectrum reconstruction was performed with a color checker as well as a set of natural objects. Both simulation and actual reconstruction results were discussed respectively. The error sources were analysed and discussed. A graphical user interface was compiled intending a simple spectra reflectance reconstruction for inexperienced users.
