PREDICTED-ROUTE PRESENTATION DEVICE AND PREDICTED-ROUTE PRESENTATION METHOD

An estimated route presentation apparatus (100) including a control device (10) is provided. The control device (10) executes an image acquisition function to acquire a captured image captured by a camera provided on the vehicle, an estimated route calculation function to: detect an end part of a diagram displayed on a road surface from an image of the road surface included in the captured image; obtain a center of gyration of the vehicle traveling, on the basis of changes in the direction and distance of the movement of the end part as the vehicle travels; and calculate an estimated route of the vehicle with reference to the center of gyration, and a presentation control function to present the calculated estimated route.
