Title: IMAGE PROCESSING METHOD, IMAGE PROCESSING MEANS AND IMAGE PROCESSING DEVICE FOR GENERATING IMAGES OF A PORTION OF A THREE-DIMENSIONAL SPACE
Abstract:
The invention relates to an image processing method for generating images of a portion of a three-dimensional space (100) with a camera cluster (10) having at least two camera devices (1, 2, 3, 4, 5) and/or with a camera cluster (10) having at least one camera device (1, 2, 3, 4, 5) which is displaceable along a spatially known path with a known movement variable. The invention is characterized in that a) the camera cluster (10) is positioned in the three-dimensional space (100), and that b) a calibration of the parameters defining the recording characteristics of the camera device (1, 2, 3, 4, 5) is carried out by the recording of calibration markings (21) arranged in the three-dimensional space (100) and by an assignment of the calibration markings (21) in the three-dimensional space (100) to at least one recording generated by the camera cluster (10), wherein the positions of the calibration markings (21) are known relative to each other in a coordinate system, and that c) values for a correction of image distortion, brightness and/or color for at least a focus area (16) with predetermined spatial distances (D) to the camera cluster (10) are calculated by means of the at least one recording generated by the camera cluster (10). The invention also relates to image processing means and to an image processing device.
