Abstract:
In this position paper, we discuss different motion estimation methods in general and especially for automotive scenarios. The advantage of 3D scene flow over 2D optical flow is explained by a typical use case. An indirect method for scene flow reconstruction from stereo disparity and optical flow is presented along with its main issue. Further, we describe how a direct estimation can benefit the overall scene flow result. These observations support our statement that research should focus more on direct 3D motion estimation in the future.
