Automatic operation vehicle
First Claim
1. An automatic operation vehicle that automatically performs an operation in an operation area, the vehicle comprising:
- a behavior acquisition unit configured to acquire behavior information including a distance of a movement of the automatic operation vehicle and a direction of the movement;
an image analysis unit configured to extract a marker included in an image captured by a camera provided on the automatic operation vehicle; and
a survey unit configured to acquire, by triangulation, position information of the marker extracted by the image analysis unit,wherein the survey unit acquires the position information of the marker using a first angle that is an angle difference between the moving direction and a direction to the marker from a first point through which the automatic operation vehicle passes during the movement in a constant moving direction, a second angle that is an angle difference between the moving direction and a direction to the marker from a second point through which the automatic operation vehicle passes during the movement in the moving direction, and a distance between the first point and the second point, the second point being different from the first point, andthe survey unit determines the first point and the second point during the movement of the automatic operation vehicle in the moving direction such that the angle difference between the first angle and the second angle approaches 90°

Abstract
An automatic operation vehicle that automatically performs an operation in an operation area is provided. A survey unit acquires the position information of the marker using a first angle between the moving direction and a direction to the marker from a first point through which the vehicle passes during the movement in a constant moving direction, a second angle between the moving direction and a direction to the marker from a second different point through which the vehicle passes during the movement in the moving direction, and a distance between the first point and the second point. The survey unit determines the first point and/or the second point during the movement of the vehicle in the moving direction such that the angle difference between the first angle and the second angle becomes close to 90°.
