摘要

The method involves recording images of a LPN at a geographical region (3) in a road network (1), and reading the respective LPN character strings. A current OCR data set is selected with a LPN image having a similarity exceeding a minimum similarity value and/or having the greatest similarity to the LPN image of the OCR data set from a database (11), if a confidence measure of the current OCR data set falls below a minimum confidence value. The LPN character strings of the OCR data set are improved using the selected OCR data set.
