Abstract
A three-dimensional distance measuring method includes: projecting at least one beam set forming a projection plane onto a surface of an object, the beam set including multiple beams transmitted according to a predetermined first path function and linearly arranged to form detection points on the surface of the object; rendering the beams reflected by the surface of the object to pass through a focus of a focusing element to form a sense image on a photosensitive memory element; obtaining a corresponding second path function according to an image formation position of each beam on the photosensitive memory element and a position of the focus of the focusing element; and calculating an intersection position of each first path function and the corresponding second path function to obtain a spatial position of each detection point on the object.
