METHOD, APPARATUS, AND COMPUTER PROGRAM PRODUCT FOR MAP GEOMETRY GENERATION BASED ON DATA AGGREGATION AND CONFLATION

A method is provided for automatically creating road and lane geometry from images representing probe data within a geographical area using data aggregation and conflation. Methods may include: receiving first observation data associated with a geographic area; processing the first observation data through a first encoder to produce first embeddings; receiving second observation data associated with the geographic area; processing the second observation data through a second encoder to produce second embeddings; establishing contrastive loss between the first embeddings and the second embeddings; producing consistent embeddings from the first embeddings and the second embeddings using the contrastive loss; generating, from the consistent embeddings, map data reflecting the first observation data and the second observation data; and updating a map database with the map data.
