Navigation device for displaying an approaching intersection
摘要:
The present invention is adapted for use with a navigation device which performs 3 dimensional display on approaching an intersection. The navigation device of the present invention comprises a direction-of -travel detection means which detects a direction in which a vehicle is travelling, a direction-to-intersection detection means which calculates the difference between the direction in which a vehicle is travelling and a direction to an intersection position, a viewpoint direction calculation means which calculates a direction to a viewpoint in order to perform 3 dimensional display based on a difference between a detected direction in which a vehicle is travelling and a calculated direction, and a display means which performs display based on a calculated viewpoint direction. In this way, even when there is a large difference between direction in which the vehicle is travelling and the direction to the position of the intersection, it is possible to display the intersection.
