20090132165 | METHOD AND ARRANGEMENT FOR DETERMINING POSITION OF VEHICLES RELATIVE EACH OTHER - A relative positioning system, an arrangement, and a method. A method for determining a position of a second vehicle relative to a first vehicle. At least an image of a field of view wherein the second vehicle is positioned within the field of view is recorded using an optical device mounted on the first. Image data is processed in a processor to determine a position of the second vehicle relative the first vehicle measuring at least one marker arranged on the second vehicle in the image. | 05-21-2009 |
20100250125 | ARRANGEMENT AND METHOD FOR PROVIDING A THREE DIMENSIONAL MAP REPRESENTATION OF AN AREA - An arrangement and a method for providing a three dimensional map representation of an area. The arrangement includes an image generating unit and a processing unit. The image generating unit is arranged to generate time recorded images. The image generating unit is arranged to provide a plurality of at least partly overlapping images each covering at least a part of the area. The processing unit is arranged to stereo process an arbitrary number of at least partly overlapping image sets generated by the image generating unit so as to provide the three dimensional map representation. A navigation unit is arranged to output time recorded navigation states related to the image generating unit. The processing unit is arranged to, for each time recorded image to be stereo processed, associate the navigation states relating to a corresponding time record. | 09-30-2010 |
20110019904 | METHOD FOR DISPLAYING A VIRTUAL IMAGE - A method for displaying a virtual image of three dimensional objects in an area using stereo recordings of the area for storing a pixel and a height for each point of the area. A method is obtained of enabling displaying of vertical surfaces or even slightly downwards and inwards inclined surfaces. Stereo recordings from at least three different stereo recordings of different solid angles are used. For each different solid angle at least one data base including data about texture and height pixel point wise is established. Data for displaying the virtual image are combined from the different data bases in dependence of the direction in which the virtual image is to be displayed. | 01-27-2011 |
20120115598 | SYSTEM AND METHOD FOR MIXING A SCENE WITH A VIRTUAL SCENARIO - A system and method for mixing a scene with a virtual scenario. An image capturing unit is arranged to capture at least one image so as to cover the scene from a first viewpoint. An image representation generation unit is arranged to generate at least one image representation based on the captured image. A game engine unit is arranged to generate a virtual scenario. An image processing unit is arranged to adapt the at least one image representation based on the generated virtual scenario so as to provide a virtual video sequence. | 05-10-2012 |
20120182399 | METHOD AND AN ARRANGEMENT FOR ESTIMATING 3D MODELS IN A STREET ENVIRONMENT - A method and arrangement for estimating 3D-models in a street environment using a stereo sensor technique. At least one pair of sensors are arranged in pairs and are mounted on a bracket. Each pair of sensors is positioned in a common plane. The sensors of each pair are positioned based upon contrast information such that low levels of contrasts in an image plane are avoided. The pairs of sensors are mutually positioned relative to an essentially horizontal plane of the bracket such that the sensors of a sensor pair are positioned horizontally at a distance from each other and one of the sensors above the horizontal plane of the bracket and the other under the horizontal plane. | 07-19-2012 |
20130027519 | AUTOMATED THREE DIMENSIONAL MAPPING METHOD - An automated three dimensional mapping method estimating three dimensional models taking advantage of a plurality of images. Positions and attitudes for at least one camera are recorded when images are taken. The at least one camera is geometrically calibrated to indicate the direction of each pixel of an image. A stereo disparity is calculated for a plurality of image pairs covering a same scene position setting a disparity and a certainty measure estimate for each stereo disparity. The different stereo disparity estimates are weighted together to form a 3D model. The stereo disparity estimates are reweighted automatically and adaptively based on the estimated 3D model. | 01-31-2013 |
20130041637 | THREE DIMENSIONAL MODEL METHOD BASED ON COMBINATION OF GROUND BASED IMAGES AND IMAGES TAKEN FROM ABOVE - A three dimensional model method based on combination of ground based images and images taken from above. An existing 3D model based on images taken from above is matched with images taken from ground level. All images including information about position and attitudes of the camera when the images from ground level and the images taken from above were taken and direction of each pixel. The method offers an automatically carried out imaging solving or at least mitigating occlusion problems. | 02-14-2013 |
20130141540 | TARGET LOCATING METHOD AND A TARGET LOCATING SYSTEM - A target locating method and a target locating system. Images of a target area are recorded utilizing recording devices carried by a vehicle. The recorded images of the target area are matched with a corresponding three dimensional area of a three dimensional map including transferring a target indicator from the recorded images of the target area to the three dimensional map of the corresponding target area. The coordinates of the target indicator position are read in the three dimensional map. The read coordinates of the target indicator position are made available for position requiring equipment. | 06-06-2013 |
