An error when using the temporary rotation angle is calculated for other motion vectors, and the number of motion vectors for which the error is within a predetermined threshold value is counted. After repeating such a process for a predetermined number of times, the temporary rotation angle with the largest number of motion vectors for which the error is within the predetermined threshold value is selected as the rotation angle of the camera. The present invention can be applied to an in-vehicle obstacle detecting device. | 08-21-2008 |

The invention proceeds from a skeleton model, which is described by a small number of nodes in 3D space and permits a good data compression of the image information when the co-ordinates of the nodes describe at any time the position of predetermined parts of the moving object. The skeleton model simultaneously represents previous knowledge of the object, by defining e.g. node pairs and optionally also node triplets in the skeleton model that describe cohesive object parts or optionally object surfaces, which are contained in the measured 2½-D image information, i.e. are visible to the camera. The skeleton model is to be fitted quickly and accurately into the image information. The fitting is effected between two images of an image sequence by the continuous displacement of the nodes and the continuous updating of the skeleton model. | 11-06-2014 |
