In order to reconstruct accurately for multi self-calibration images with marked point occlusions

this paper proposes a method for reconstruction and camera poses recovery from multi self-calibration images with marked point occlusions.Compared to previous methods

this method uses a way of marked point: coded point and non-coded point.The coded points are utilized for a single CCD camera self-calibration and camera poses recovery and the non-coded points are utilized for 3D points reconstruction.The novelties of the proposed method are three-fold.Firstly

the problem of manually selected image point correspondences is avoided by using auto match of marked points.Secondly

the proposed method is based on marked points

the precision of 3D reconstruction is improved since match of marked point is accurate.Thirdly

the robustness is markedly increased since the effect of noise on the marked points of images is small.The practice shows that the results are accurate and reliable so as to meet the requirements of reverse engineering applications.
