Abstract: A method for measuring angular displacement of markless objects with spherical surface is presented in this paper. Some theoretical conclusions are obtained and approved by experiments. The method is approved to have features of simplicity,practicality and high ac-curacy. The conclusions are experimentally extended to general cases.
