Method for monitoring of stereo camera arrangement used for detecting environment of e.g. vehicle during manufacturing vehicle, involves determining confidence measure indicating efficiency and/or reliability of arrangement

摘要

The method involves stereoscopically processing image data by a processing unit (1.3). Disparities for pixels (BP1, BP2) of an image pair are estimated in the image processing. A disparity card (D) is produced from the estimated disparities. A relative density (X) of the estimated disparities on the card and/or a disparity error (Y) is determined from a deviation of the estimated disparities from expected disparities. A confidence measure (F) indicating an efficiency and/or a reliability of stereo camera arrangement (1) is determined from the relative density and the disparity error.
