Abstract

A method for aligning two map datasets. The method includes: providing two map datasets, each containing environmental information, wherein the environmental information in the two map datasets has been detected by a sensor of a mobile device, and at least one of the two map datasets is a sparse map dataset; providing the two map datasets as input feature data or determining input feature data based on the two map datasets; carrying out an alignment of the two map datasets using a machine learning algorithm based on sparse convolution, wherein output data including information about a transformative relation between the two map datasets are generated from the input feature data, via intermediate feature data in one or more intermediate layers.
