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.

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 for precise position correction using a positioning difference comprises a first distribution information obtaining unit gathering first distribution information from an external terminal, a global navigation satellite system (GNSS) receiver obtaining a GNSS positioning value of the apparatus based on a GNSS, and a positioning correcting unit obtain a corrected location of the apparatus by correcting the GNSS positioning value using the gathered first distribution information. The first distribution information includes a GNSS positioning value of the external terminal, a GNSS positioning time, a precise positioning value, and a positioning difference between the GNSS positioning value and the precise positioning value.
