Title: METHOD AND SCANNING SYSTEM FOR COMPUTING A USE CASE SPECIFIC SCAN ROUTE
Abstract: In summary, the invention relates to a method and mobile scanning system for computing a use case specific scan route. The method comprises the steps:determining a position of the mobile scanning device in the scanning environment;capturing scanning environment information by a capturing system of the mobile scanning device in a surrounding area of the mobile scanning device within the scanning environment starting from the determined position of the mobile scanning device in the scanning environment;generating a digital environmental representation of the scanning environment comprising the determined position of the mobile scanning device and the captured scanning environment information, wherein the digital environmental representation is updated with further captured scanning environment information while the mobile scanning device is moving or is moved in the scanning environment;computing the use case specific scan route of the mobile scanning device on the basis of the created digital environmental representation of the scanning environment.In this way, a dynamic ad-hoc planning of a scan route for a mobile scanning device may be achieved.
