APPARATUS AND METHOD FOR GENERATING DISTRIBUTION INFORMATION ABOUT POSITIONING DIFFERENCE BETWEEN GNSS POSITIONING AND PRECISE POSITIONING BASED ON IMAGE AND HIGH-DEFINITION MAP

According to an embodiment, an apparatus and method for generating distribution information may include periodically generating GNSS information including GNSS positioning information and a positioning time, generating image information including an image of at least one or more facility object, at the positioning time, while a vehicle drives, obtaining precise positioning information for a capturing position at the positioning time based on the image information, a high-definition map, and the GNSS information, calculating a positioning difference which is a difference between the GNSS positioning information and the precise positioning information, and generating distribution information including the GNSS information, the positioning difference, and the precise positioning information. The high-definition map includes information for feature point spatial coordinates and a property for each facility object.
