Abstract
A processor of a distance measuring apparatus calculates a three-dimensional position of an object in the surroundings based on the first image, the second image and the amount of movement. The processor determines that calculated three-dimensional position is an error, when the displacement between a fourth position at which a third position set based on the calculated three-dimensional position of the object is projected on either one image of the first image and the second image and a position of the object in the one image is equal to or larger than a prescribed value. The processor makes the calculated three-dimensional position a distance measurement target when the calculated three-dimensional position is not determined as an error, and when determined as an error, excludes the calculated three-dimensional position from the distance measurement target.
