Abstract: A computerised method of creating map data from a plurality of trips where each trip comprises position data derived from the positions of at least one navigation device 200 over a period of time, the method comprising using a processing circuitry to perform the following steps: i. processing the position data; ii. determining from the processing the believed accuracy of the position data constituting a trip; iii. reducing the weight applied to and/or removing position data in which the belief is below a predetermined threshold to generate filtered position data; iv. deriving information about the road 700 based upon the filtered position data; and v. generating further map data.

Abstract: A method of producing a multi-viewpoint panorama of a roadside is disclosed. In at least one embodiment, the method includes acquiring a set of laser scan samples obtained by at least one terrestrial based laser scanner mounted on a moving vehicle, wherein each sample is associated with location data and orientation data; acquiring at least one image sequence, wherein each image sequence is obtained by use of a terrestrial based camera mounted on the moving vehicle, wherein each image of the at least one image sequences is associated with location and orientation data; extracting a surface from the set of laser scan samples and determining the location of the surface in dependence of the location data associated with the laser scan samples; and producing a multi-viewpoint panorama for the surface from the at least one image sequence in dependence of the location of the surface and the location and orientation data associated with each of the images.

Abstract: A computer arrangement is disclosed, including a processor that can communicate with a memory. The memory stores a computer program that can be run by the processor, and stores a set of laser scan samples including a sub-set of laser scan samples relating to a façade of a building and stores location data as to each laser scan sample. The memory also stores a picture of the same façade including location data as to pixels of the picture. The picture includes data as to a wall of the façade and data as to texture elements in the wall. In at least one embodiment, the processor automatically identifies the wall and the texture elements in the picture while using the laser scan samples.

Abstract: A method of detecting objects from terrestrial based mobile mapping data is disclosed, wherein the terrestrial based mobile mapping data has been captured by way of a terrestrial based mobile mapping vehicle driving on a road having a driving direction, the mobile mapping data including laser scanner data, source images obtained by at least one camera and position and orientation data of the vehicle, wherein the laser scanner data includes laser points, each laser point having associated position and orientation data, and each source image comprises associated position and orientation data.
