Document Type and Number:
Japanese Patent JP5046310
Kind Code:
B1
Abstract:
PROBLEM TO BE SOLVED: To provide an unmanned vehicle capable of running to all directions while correcting an attitude angle even with only two imaging means, and an unmanned carrier system including the unmanned vehicle.SOLUTION: An unmanned vehicle 10 includes two imaging means 11a and 11b for respectively outputting image data of regions Aand A, an attitude angle calculation part for calculating an attitude angle on the basis of the image data, and a steering control part for controlling a steering angle of a wheel 15 so that the attitude angle becomes zero. When the vehicle runs to a first direction, the attitude angle calculation part calculates the attitude angle on the basis of a position of a guide line in two image data output from the two imaging means 11a and 11b. When the vehicle runs to a second direction, the attitude angle calculation part calculates the attitude angle on the basis of a position of the guide line in one image data output from the imaging means 11a or calculates the attitude angle on the basis of a position of a marker in two image data output from the two imaging means 11a and 11b.
