<P>PROBLEM TO BE SOLVED: To increase efficiency in processing for creating a correspondence table between a world coordinate system of a vehicle to be acquired by an on-vehicle device loaded on a vehicle and a camera coordinate system of the vehicle to be acquired by a roadside device. <P>SOLUTION: A position coordinate correspondence table creation system has: an on-vehicle device 20 which acquires position coordinate data of a world coordinate system of a vehicle, and intermittently outputs a light source/heat source in a pattern that an interval between them becomes unequal; a roadside device 10 which photographs the vehicle; and a position correspondence table creation part 30 which performs time synchronization of the position coordinate data of the world coordinate system of the vehicle and position coordinate data of a camera coordinate system of the vehicle based on output timing information on the light source/heat source in the on-vehicle device 20 and output timing of the light source/heat source included in an image photographed with the roadside device 10 to create a correspondence table between the position coordinate data of the world coordinate system for the vehicle and the position coordinate data of a camera system coordinate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
