A Complete-view Stereo Imaging Method for Three-dimensional Reconstruction of Objects

This paper designs a configuration of a coaxial complete-view stereo imaging system based on single camera and cylinder-conical mirror for three-dimensional reconstruction of objects.We also introduce a projective mapping algorithm between the object-points and the image-points of complete-view image.The circinal stereo image pairs that have complete-view information can be gained through two reflections of the cylinder-conical mirror.In the circinal stereo image pairs,there is a correlation between object-points and image-points that corresponds to the restriction of epipolar line.On the basis of projection,stereo image-points matching is done,so the three-dimensional coordinate values of relevant object-points can be gained according to the coordinate positions of image-points.Finally,after the simulated experiment based on the 3DS MAX virtual equipment,we implement objects' three-dimensional reconstruction and its complete-view browsing,which demonstrates the validity of the algorithm.
