MAP GENERATION APPARATUS

A map generation apparatus includes a microprocessor configured to perform: extracting feature points from detection information detected by an in-vehicle detection unit; selecting feature points for which three-dimensional positions are to be calculated from extracted feature points; based on a plurality of the detection information, calculating the three-dimensional positions of same feature points in the plurality of the detection information for the selected feature points by using a position and posture of the in-vehicle detection unit; and generating a map including information of each of the three-dimensional positions by using the three-dimensional positions of the calculated feature points, wherein the microprocessor is configured to perform the selecting including selecting the feature points on an object with a high priority among a plurality of objects included in the detection information based on a priority information set for each of the plurality of objects in advance.
