Abstract
A free space positioning method for estimating an attitude angle of an object in a free space includes: capturing an image of a light source module that includes four light sources to generate a to-be-judged image; analyzing coordinates of the light sources in the to-be-judged image to obtain to-be-judged information; comparing the to-be-judged information with pre-stored light source orientation data to obtain candidate light source orientation data; and estimating an attitude angle of the object according to a pre-stored attitude angle corresponding to each of the candidate light source orientation data.
