INFORMATION PROCESSING DEVICE

Title:

INFORMATION PROCESSING DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/071117

Kind Code:

A1

Abstract:

Provided is an information processing device capable of efficiently correcting an absolute position of point group information. In a server device (10), a point group integration unit (11) acquires point group data generated on the basis of sensor data obtained by a sensor (1) mounted in a vehicle V and absolute position data of the vehicle V when the sensor data is acquired, and a deviation amount calculation unit (14) acquires aerial photograph data overlooked the ground surface from the sky. Then, the deviation amount calculation unit (14) calculates a deviation amount between the absolute position on the aerial photograph data corresponding to the set reference points P, Q and the absolute position of the point group contained in the point group data corresponding to the reference points P, Q, and a trajectory correction unit (15) corrects a travelling trajectory extracted from the point group data by a trajectory extraction unit (12) on the basis of the deviation amount calculated by the deviation amount calculation unit (14) and corrects the absolute position of the point group of the point group data on the basis of the correction result of the trajectory correction unit (15).
