MAP INFORMATION CORRECTION DEVICE, MOVING BODY, MAP INFORMATION CREATION DEVICE, MAP INFORMATION CORRECTION SYSTEM, MAP INFORMATION CORRECTION METHOD AND MAP INFORMATION CORRECTION PROGRAM

摘要

Conventionally, map information correction devices could not be applied to autonomous driving or collision avoidance warnings because too much time was required to correct maps that have a fast update period such as dynamic maps.　This map information correction device (4) comprises a feature point priority determination unit (41) which determines a priority for a feature point of local moving body periphery information on the basis of the priority table (61); a feature pair priority determination unit (42) which, if there are one or more feature pairs in which a local moving body periphery information feature point and a received map information feature point correspond, assigns a priority to the feature pair on the basis of the local moving body periphery information priority of the feature pair and the map information priority of the feature pair; an error calculation unit (43) which calculates the error in map information on the basis of a high-priority local moving body periphery information feature point, which is a local moving body periphery information feature point, and a high-priority map information feature point, which is a map information feature point, that make up a high-priority feature pair; and a correction unit (44) which corrects the map information on the basis of the error.
