Abstract: A method and system for estimating a position of a mobile device is disclosed. In particular, a method and system in which the position of a mobile device is determined using measurements of received Global Navigation Satellite System, GNSS, satellite signals is disclosed. The present invention therefore proposes to qualify a received satellite signal based on whether a signal propagation characteristic of this signal falls within an expected range of this characteristic. The expected range is determined using information about the satellite that sent the signal. The position of the mobile device is computed based on the validated satellite signals.

Abstract: The present invention is related to an image stitching method. It is further related to an image stitching device and to a computer readable medium carrying instructions for performing such method. The method according to the invention includes determining a pixel value of a pixel at an interpolation position in the region to be stitched using pixel values of corresponding pixels in a plurality of sub-images. According to the invention, the interpolation position corresponds to a weighted sum of positions of the corresponding pixels. The weighting factor for the position of a corresponding pixel in a given sub-image depends on a relative distance of at said interpolation position to a border of the region to be stitched associated with that sub-image.

Abstract: A method and system for improving position information associated with a collection of images is disclosed, more in particular, a method and system for improving position information of images obtained using a camera system including at least one camera mounted on or to a vehicle. A 3D model is constructed from an overlapping region in which at least two images obtained at different positions of the vehicle among the collection of images at least partially overlap. By comparing the 3D model to an aerial image, the position of the 3D model can be updated.

Abstract: A method for generating a panoramic image includes providing a 3D point model of an area surrounding a virtual viewpoint, acquiring multiple images of the area surrounding the virtual viewpoint, projecting the acquired images onto the 3D point model and generating the panoramic image using the thus obtained 3D point model of the surrounding area.

Abstract: Method for producing a digital photo comprising pixels, wherein at least some of the pixels comprise position information, the method comprising of: taking a photo with a known geometry of the optical system with which the photo is taken; recording the position from which the photo has been taken; recording the direction in which the photo has been taken; providing a three-dimensional model comprising points which are comprised by at least an outer surface of an object in the field of view of the position where the photo has been taken, wherein the points comprise position information; relating a pixel on the one hand and a corresponding point in the three-dimensional model on the other; and recording, in a manner associated with the pixel, the position information of the corresponding pixel.

Abstract: The present invention relates to a system, a device, and vehicle for recording panoramic images. According to the present invention, panoramic images can be obtained using a plurality of optical cameras and light directing elements which are arranged based on a parabola. This allows a compact device to be obtained while ensuring that each camera records a partial image as if it were at substantially the same focus point as the other cameras. By arranging the plurality of cameras and light directing elements such that the respective focus points are slightly offset relative to each other, a slight overlap between adjacent field of views can be obtained to improve stitching of the partial images to from the panoramic image.

Abstract: The present invention relates to an apparatus and method for detecting and recognizing an object in an image, the method comprising a plurality of stages, wherein at least one of the stages comprises an integrated approach of feature detection and object recognition of at least a part of the object. In a further embodiment at least one of the stages comprises identifying an image part that contains a feature point, and matching the image part to a set of hierarchies of templates, wherein a hierarchy comprises templates for an object to be recognized, a template describes at least a part of an object to be recognized, and a child template describes a sub-part of the part of the object described by its parent template.
