Determining the transmission quality of an optical unit in a camera system
A method for determining the transmission quality of an optical unit in a camera system to draw conclusions about dirt and/or wear in the optical unit and particularly to determine whether the optical unit requires servicing, includes transforming spatially resolved information relating to at least one image from the camera system sectionally using a frequency transformation so that a sequence of transformation coefficients is determined for each section of the at least one image. Each transformation coefficient is a measure of the energy in a specific frequency range. At least one sequence of transformation coefficients having the highest energy values for the highest frequencies is selected. Using the at least one selected sequence a distribution of the frequencies is determined, the distribution of the frequencies is compared with a reference, and the transmission quality of the optical unit is determined using the comparison. |
