Abstract

The invention discloses a method for three-dimensional positioning. The method is used for performing three-dimensional positioning on a to-be-positioned object in an interested space, and three-dimensional space coordinates and the direction of the to-be-positioned object are reflected through three-dimensional space coordinates of a photosensitive sensor of a positioning device assembled on the to-be-positioned object. The method comprises a step a) of performing timing on a plurality of light sources having the same emission wavelength, and determining the time and sequence of scanning an interested space by the light sources; a step b) of using plane laser to scan the interested space according to the scanning sequence, so as to irradiate the photosensitive sensor located in the interested space; a step c) of recording time data of the photosensitive sensor subject to plane laser irradiation; a step d) of judging validity of the recorded time data; a step e) of calculating the three-dimensional space coordinates of the photosensitive sensor according to the valid time data; and repeatedly executing the steps b) to e) until the execution of the method is stopped. Moreover, the invention further discloses a system for three-dimensional positioning.
