摘要： The invention relates to a method for identifying a difference between a first 3D model of an environment and a second 3D model of the environment. The first and second 3D model each comprise a plurality of points or parts, wherein each point or part of the first and second model comprises geometrical information and texture information. Corresponding points or parts of the first and second 3D model are matched based on the geometrical information and/or the texture information. The matched points or parts of the first and second model are compared to determine at least one difference value based on the geometrical information and the texture information of the first and second model. A difference between the first and second model is identified if the at least one difference value exceeds a predetermined value. The invention also relates to an arrangement, a computer program, and a computer program product. The invention further relates to a method for identifying a difference between a 3D model of an environment and the environment as reproduced at another timing, to a further arrangement, a further computer program, and a further computer program product.

摘要： The present invention relates to a method for displaying a virtual image of three dimensional objects in an area using stereo recordings (23) of the area for storing (24) a pixel and a height for each point of the area. The object of the invention is to obtain a method enabling displaying of vertical surfaces or even slightly downwards and inwards inclined surfaces. The object is obtained by a method using stereo recordings from at least three different stereo recordings of different solid angels. For each different solid angel at least one data base comprising data about texture and height pixel point wise is established. Data for displaying the virtual image are combined (26) from the different data bases in dependence of the direction in which the virtual image is to be displayed (27).
