A processing unit in the system is configured to receive at least two sets of image data from the imaging sensor, with each set of image data acquired at a different rotational position of the wheel assembly around an axis of rotation and representative of at least one visible target element on each of the two surfaces, from which the processing unit is configured to identify said axis of rotation of the wheel assembly. | 2011-12-29 |
20110316980 | Method of estimating a motion of a multiple camera system, a multiple camera system and a computer program product - The invention relates to a method of correcting a bias in a motion estimation of a multiple camera system in a three-dimensional (3D) space, wherein the fields of view of multiple cameras at least partially coincide. The method comprises the step of computing a first and second set of distribution parameters associated with corresponding determined 3D positions of image features in subsequent image sets. Further, the method comprises the step of estimating a set of motion parameters representing a motion of the multiple camera system. The method also comprises the steps of improving the computed first or second set of distribution parameters and improving the estimated set of motion parameters. Further, the method comprises calculating a bias direction based on the initially estimated set of motion parameters and on the improved estimated set of motion parameters. | 2011-12-29 |
20110316981 | PROCESSOR - A processor includes: an imaging control unit which causes an imaging unit for capturing an image with changing a focused object distance, to change the focused object distance with a first change width in the case of a first focused object distance, and to change the focused object distance with a second change width that is smaller than the first change width in the case of a second focused object distance that is shorter than the first focused object distance; and an image processing unit which extracts focused object image data from captured image data for each of the focused object distances, and generates image data by shifting the extracted object image data by parallax amounts corresponding to the respective focused object distances, and by synthesizing the extracted object image data. | 2011-12-29 |
