System and method for detecting information about road relating to digital geographical map data

A system for detecting information about a road relating to digital geographical map data for an area including a plurality of road segments, the system comprising:

• an input device configured to obtain remotely captured geographical image data for the area;
• and
• a processor configured to generate ground truth image data from the digital geographical map data, and generate binary image data of the road segments from the remotely captured geographical image data using a semantic segmentation task,
• wherein the processor is further configured to:
• skeletonize the binary image data to generate skeletonized binary image data including a center line of each road segment of the road segments,
• detect a first road segment missing from the digital geographical map data by converting the skeletonized binary image data to a graph structure of the road segments and comparing the graph structure of the road segments with the ground truth image data,
• detect a road width of each road segment of the road segments from the binary image data and the center line of each road segment of the road segments;
• and
• detect number of lanes of each road segment of the road segments from the detected road width.
