Abstract

An information processing apparatus includes a three-dimensional map data storage unit for storing three-dimensional map data for use in projecting a three-dimensional space on a map onto a plane, a location information storage unit for storing location information including a type of geographical objects at points spaced at predetermined intervals on the map, a present position storage unit for storing a present position on the map, an operation input receiving unit for receiving an operation input, a collision determination unit for determining the possibility of occurrence of collision in a course from the present position to an end point, a correction unit for correcting the end point based on the determined possibility of occurrence of collision and shifting the present position to the corrected end point, and a drawing unit for drawing a three-dimensional image, the three-dimensional image produced by projecting onto the plane the three-dimensional space on the map.

Claims

1. An information processing apparatus, comprising:

circuitry configured to;

determine occurrence of collision in a course from a present position to an end position on a map displayed on a display screen, based on the present position and a type of a geographical object, if an operation input to proceed from the present position on the map to an end point on the map is received;

correct the end point, when the circuitry determines that a collision will occur, by selecting, from among a plurality of points, a corrected end point based on a distance from the present position and a type of a geographical object, wherein selecting includes determining if the corrected end point is on the course and, if the corrected end point is not on the course, selecting another corrected end point; and

draw a three-dimensional image, the three-dimensional image corresponding to the present position on the map displayed on the display screen.

2. The information processing apparatus according to claim 1, wherein the circuitry shifts the end point toward the present position if the circuitry determines that a collision will occur.

3. The information processing apparatus according to claim 1, wherein the plurality of points are arranged in a grid-like configuration on the map.

4. The information processing apparatus according to claim 1,

wherein the course is a road on the map;

wherein the circuitry stores location information related to a direction of movement on the road of the map; and

wherein the circuitry corrects a directional vector for the present position to the direction of movement contained in the location information at the corrected end point.

5. The information processing apparatus according to claim 1,

wherein the location information comprises altitude data at points at the predetermined intervals on the map;

and

wherein the circuitry corrects a position of a viewpoint in the direction of course based on the altitude data contained in the location information present at a position closest to the present position in the direction of course from the present position to the end point.

6. The information processing apparatus according to claim 1,

wherein the location information comprises altitude data at points at the predetermined intervals on the map;

and

wherein if a plurality of pieces of altitude data are contained in the location information present at a position closest to the present position in the direction of course from the present position to the end point, the circuitry corrects a position of a viewpoint in the direction of course based on altitude data indicating an altitude closest to an altitude of the present position of the plurality of pieces of the altitude data.

7. A control method of an information processing apparatus including circuitry, the control method comprising:

determining occurrence of collision in a course from a present position to an end position on a map displayed on a display screen, based on the present position and a type of a geographical object, if an operation input to proceed from the present position on the map to an end point on the map is received;

correcting the end point, when the circuitry determines that a collision will occur, by selecting, from among a plurality of points, a corrected end point based on a distance from the present position and a type of a geographical object, wherein selecting includes determining if the corrected end point is on the course and, if the corrected end point is not on the course, selecting another corrected end point; and

drawing a three-dimensional image, the three-dimensional image corresponding to the present position on the map displayed on the display screen.

8. A non-transitory computer-readable storage medium storing instructions executable by a processor for causing a computer to perform a control method of an information processing apparatus including circuitry, the control method comprising:

determining occurrence of collision in a course from a present position to an end position on a map displayed on a display screen, based on the present position and a type of a geographical object, if an operation input to proceed from the present position on the map to an end point on the map is received;

correcting the end point, when the circuitry determines that a collision will occur, by selecting, from among a plurality of points, a corrected end point based on a distance from the present position and a type of a geographical object, wherein selecting includes determining if the corrected end point is on the course and, if the corrected end point is not on the course, selecting another corrected end point; and

drawing a three-dimensional image, the three-dimensional image corresponding to the present position on the map displayed on the display screen.
