Abstract The present invention relates to the field of three-dimensional sensing and measurement technology. The space encoding method includes that each encoded area is corresponding to different code word; that Hamming distance between adjacent areas is always 1; that on each physical point, there are at least the chances for one bright fringe and one dark fringe to project; and that the minimum width for the projected fringe to separate is twice width of viewing field of a pixel. The present invention has the features of high efficiency and small error.
