Abstract (en)
[origin: WO2023006213A1] For continuous and smooth localization in an area, a supporting apparatus is provided. The supporting apparatus splits the area into multiple sub-areas and generates one or more reference positions in the area. For each reference position, the supporting apparatus computes one or more transformations that transform neighbouring 2D/3D maps of the sub-area around the reference position to ensure that the neighbouring 2D/3D maps are aligned. The one or more transformations are associated with the reference position and may be stored in a database. During navigation, a navigation apparatus determines a closest reference position based on a current position, and obtains associated one or more transformations. Then, the navigation apparatus dynamically stitches maps of neighbouring sub-areas based on the one or more transformations and provides navigation based on the stitched maps.
