Apparatus for evaluating images from a multi camera system, multi camera system and process for evaluating

An apparatus for evaluating images from a multi camera system is proposed, the multi camera system comprising a main camera for generating a main image and at least two satellite cameras for generating at least a first and a second satellite image. The cameras can be orientated to a common observation area. The apparatus is operable to estimate a combined positional data of a point in the 3D-space. of the observation area corresponding to a pixel or group of pixels of interest of the main image. The apparatus comprises first disparity means for estimating at least a first disparity data concerning the pixel or group of pixels of interest derived from the main image and the first satellite image, second disparity means for estimating at least a second disparity data concerning the pixel or group of pixels of interest derived from the main image and the second satellite image, and positional data means for estimating the combined positional data of the point in the 3D-space of the observation area corresponding to the pixel or group of pixels of interest. The positional data means is operable to estimate first positional data on basis of the first disparity data and second positional data on basis of the second disparity data, and to combine the first positional data and the second positional data to the combined positional data.
