Abstract
The self-position calculating apparatus includes: a patterned light beam extractor extracting a position of the patterned light beam an image of an area onto which the patterned light beam is projected. The apparatus calculates an orientation angle of the vehicle relative to the road surface from the position of calculates an amount of change in orientation of the vehicle based on temporal changes in multiple feature points on the road surface; and calculates 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. If a detected condition of the patterned light beam is equal to or greater than a threshold value, the patterned light beam extractor extracts the position from a superimposed image by superimposing images.
