Three dimensional (3D) shape lies an unresolved and active research topic on the cross-section of computer vision and
digital photogrammetry. In this paper, we focus on 3D object shape reconstruction from uncalibrated images and put
forward a hybrid method. The recovering 3D shape comprises two steps, firstly, calculate homography transformation to
obtain the outlines, secondly, calculate the reconstructed object height by vanishing point and vanishing line from
reference height. This hybrid method requires no camera calibration or the estimation of the fundamental matrix; hence,
it reduces the computational complexity by eliminating the requirement for abundant conjugate points. The experiment
shows that the method is much validated and something useful is obtained.
