Abstract
A fast and accurate coded marker identification method is presented in this paper. The method combines image processing techniques with prior information of markerpsilas appearance and shape. The deformation of the circle caused by projection is considered so that the marker can be recognized correctly. The experiments demonstrate the robustness and accuracy of our method.
