A self-position calculating apparatus includes: a light projector 11 configured to project a patterned light beam onto a road surface around a vehicle; an image capturing unit 12 installed in the vehicle, and configured to capture and obtain an image of the road surface around the vehicle covering an area of the projected patterned light beam; an orientation angle calculator 22 configured to calculate an orientation angle of the vehicle relative to the road surface from a shape of the patterned light beam on the image obtained with the image capturing unit 12; a feature point detector 23 configured to detect multiple feature points on the road surface from the image obtained with the image capturing unit 12; an orientation change amount calculator 24 configured to calculate an amount of change in the orientation of the vehicle based on temporal changes in the multiple feature points on the road surface detected by the feature point detector 23; and a self-position calculator 25 configured to calculate a current position and a current orientation angle of the vehicle by adding the amount of change in the orientation to an initial position and an initial orientation angle of the vehicle relative to the road surface. Depending on how the feature points on the road surface are detected by the feature point detector, the light projector 11 selectively projects the patterned light beam onto a specific patterned light beam-projected region out of the multiple patterned light beam-projected regions.
