由序列图像获取点目标的三维运动参数和空间位置

利用图像获取目标的运动参数和空间位置在目标定位、跟踪和计算机视觉中具有重要的意义。本文在目标和成像系统都运动的情况下，给出了由单目序列图像获取点目标绝对运动参数和三维空间坐标的条件，提出了利用多帧单目序列图像和应用非线性递推滤波算法来估计点目标的运动参数和空间位置。实验仿真结果证明，本文提出的算法是有效的。

3D Motion Estimation of Point Target From a Monocular Image Sequence

Estimating motion parameters and spatial position of object is very important in target tracking and computer vision.The constraint for obtaining 3D motion and coordinates from a monocular image sequence is first presented and proved in this paper.With this contraint,a nonlinear recusive filtering algorithm for estimation 3D motion parameters and 3D spatial position of a point target from monocular images has been proposed.The performance of the proposed technique on simulated image sequence is also involved.
