Feature data generation system, feature database update system, and feature data generation method

摘要

PROBLEM TO BE SOLVED: To provide a feature data generation system capable of ensuring the accuracy of a feature database. SOLUTION: In a feature data generation system 100, based on image data around a vehicle 200 obtained by imaging from position data of a large number of measurement points around the vehicle 200 measured by using the LIDAR technique. The edge pattern indicating the boundary of the target feature existing around the vehicle 200 is extracted to reduce the amount of information, the extracted edge pattern is given the position of the absolute coordinate system, and the position of the absolute coordinate system is given. From the edge pattern, a shape feature vector and a feature feature vector used to generate or update a feature in the feature database are generated. [Selection diagram] FIG. 14
