Arrangement and method for processing image data
First Claim
Patent Images
1. An arrangement for processing image data in imaging systems for occupant protection systems, comprising:
- a first control unit which, in real time, reads out from at least one image sensor, grayscale values of the image data as source image pixels;
an optical system which distorts the image data, where the first control unit corrects the image data distorted by the optical system using a tabular mapping rule so that a target image is produced and provides range information of the target image; and
a second control unit for controlling the first control unit and taking over the target image data and the range information of the target image processed by the first control unit, the second control unit performing seat occupancy classification, whereinby mapping the source image into the target image according to the mapping rule, the target image having fewer pixels than the source image can be obtained.

Abstract
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.

7. A method for processing image data in imaging systems for occupant protection systems, comprising:
-
reading the image data available in an image sensor of a source image distorted by an optical system from the image sensor by a first control unit in which the image data is corrected in real time using a tabular mapping rule so that a target image is produced and is provided with range information, whereby a seat occupancy classification is carried out using in a second control unit which controls the first control unit, the corrected target image data and range information taken from the first control unit is provided with range information and classified, wherein the target image has fewer pixels than the source image. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
