Abstract The present invention relates to the field of three-dimensional sensing and measurement technology. The method includes the first coarse space coding of projected black and white fringe pattern to measured space to realize coarse separation to measured three-dimensional contour and the subsequent fine separation of coarsely separated space by using pattern with gradually changed gray scale. The present invention has the features of high measurement accuracy and no limitation of hardware performance.
