单目视频运动目标轨迹三维重建的平滑约束法
摘要
In this paper, generic smoothness constrained 3D trajectory reconstruction of moving object from monocular video is proposed. By introducing the generic smoothness constraint on the 3D trajectory, uncon- strained optimization model for 3D trajectory reconstruction is achieved and a closed-form solution is derived. Compared with the prede ned basis methods such as Discrete Cosine Transform based method and polynomial basis based method, the proposed method is more generic and can be applied to incomplete measurement case, thus having broad applicability. Geometric explanation and uniqueness of 3D trajectory reconstruction are given. Experimental results on both synthetic data and real monocular video sequences have shown the validity and advancement of the proposed method.
