Abstract (en)
[origin: WO2022084182A1] The invention relates to a method for providing mapping data (160) for a map (170) of a deployment environment (100) for at least one mobile unit (120), said method comprising the steps of reading reference image data from an interface of image capture device (122) of the mobile unit (120). The reference image data represent a plurality of reference images which are recorded by means of the image capture device (122) from portions (104) of a ground surface (102) of the deployment environment (100) that are specific to each reference image, with adjacent portions (104) overlapping in part. A plurality of reference image features is extracted for each reference image with use of the reference image data. Positions of the reference image features in each reference image are determined by means of a random process or in accordance with a predefined distribution schema. To generate mapping data (160), a reference feature descriptor is determined at the position of each reference image feature with use of the reference image data. The mapping data (160) comprises the reference image data, the positions of the reference image features and the reference feature descriptors.
