摘要： PROBLEM TO BE SOLVED: To provide a road image compositing technology for compositing an accurate road image even when there is a change in inclination, direction, or speed of a traveling vehicle, and in road gradient.
SOLUTION: In a road image creation system, the road image of the road ahead imaged from the traveling vehicle is stored in an image storage means 6. Location coordinate data of the vehicle measured in synchronization with the imaging of each road image is stored in a location history storage means 10. An image conversion means 12 creates an orthographic image (orthographic road image) of the road surface by applying orthographic projection conversion to each road image. An image compositing means 13 determines, according to the location coordinate data of each orthographic road image measured by the vehicle location measuring means, the world coordinate and direction of the orthographic road image, and arranges each orthographic road image on a horizontal plane of projection in the determined world coordinate system respectively to composite a linked road image. At this time, corrections according to the location, attitude, and height of the vehicle are applied to the orthographic projection.
