Intersection guidance display system, method and program

Abstract

The present invention provides a technology capable of recognizing the positional relationship between two intersections existing on a planned travel route and easily recognizing a part that should be paid attention to at present. The intersection guidance display system of the present invention includes: a display unit for superimposing and displaying an image representing a route figure along the planned driving route on a bird's-eye view of a road including two intersections on the planned driving route; and setting a viewpoint A unit that fixes the viewpoint of the bird's-eye view to the route based on the vehicle's planned travel route until it travels at the first intersection during the first period until the vehicle travels at the first intersection on the planned travel route. That is, the first position set by the first route, and during the second period when the vehicle travels between the first intersection and the second intersection on the planned travel route, the viewpoint of the bird's-eye view is fixed to the In the predetermined route, the second position is set as the route between the first intersection and the second intersection, that is, the second route. During the second period, the vehicle has just passed the travel plan During the movement period after the first intersection on the route, the viewpoint of the bird's-eye view is placed on the moving line linking the first position and the second position from the first position toward the second position Move aggressively.

Description

technical field [0001] The present invention relates to an intersection guidance display system, method and program for displaying guidance for intersections. Background technique [0002] A technique is known in which a thumbnail image is prepared for each of a plurality of intersections existing on a route, and the thumbnail images are shifted and displayed superimposedly in the order of passing through the intersection (see Patent Document 1). In Patent Document 1, by operating buttons such as "Forward" and "Back", it is possible to switch the intersection whose thumbnail image was displayed most recently. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2004-117264 [0004] However, in Patent Document 1, since the thumbnail images are independently prepared for each intersection, there is a problem that it is difficult to recognize the positional relationship between each intersection. On the other hand, if one thumbnail image including each intersection is di...

Problems solved by technology

However, since the thumbnail image is not switched, there is a problem that it is not possible to recognize whether the vehicle has passed the intersection or not, the part that should be focused on in the thumbnail image.
