TitleStructure from Motion in Dynamic Scenes with Multiple Motions
AbstractIn this study, an algorithm is proposed to solve the multibody
structure from motion (SfM) problem for the single
camera case. The algorithm uses the epipolar criterion to
segment the features belonging to independently moving
objects. Once the features are segmented, corresponding
objects are reconstructed individually by applying a sequential algorithm, which uses the previous structure to
estimate the pose of the current frame. A tracker is
utilized to increase the baseline and improve the F-matrix
estimation, which is beneficial for both segmentation and
3D structure estimation. The experimental results on
synthetic and real data demonstrate that our approach
efficiently deals with the multi-body SfM problem.
