Abstract
A self-location calculating device projects a patterned light onto a road surface around a vehicle, as well as thereby captures and obtains an image of the road surface around the vehicle. Furthermore, the self-location calculating device detects a running condition of the vehicle. When it is determined that the vehicle is a running stable state, the self-location calculating device calculates a current position and a current attitude angle of the vehicle by adding an amount of change in an attitude to a predetermined initial attitude angle of the vehicle.
