Patent number: 7327856Abstract: A source image (S1) distorted by a camera lens can be transformed into a rectified target image (T), by means of a tabular imaging specification. The above occurs during read-out from the image sensor and in real-time. Each source pixel in the source image is assigned none, one or several target pixels in the target image (T1). A first controller (C1) controls the image sensors (B1, B2) accurately with tine and the image equalization and image correlation. A second controller (C2) controls the first controller (C1) and works in a manner temporally decoupled from the above.Type: GrantFiled: May 25, 2001Date of Patent: February 5, 2008Assignee: Siemens AktiengesellschaftInventors: Horst Belau, Reinhard Rosl, Stefan Spalke, Ulrich Wagner
