【摘要】 通过利用三维点的仿射坐标对于刚体变换而言是不变的,并且对计算机坐标系到图像坐标系的坐标变换而言也是不变的这一特性,开发了从一个目标单视图线性复原其三维位姿的新算法,该算法只需4个特征点即可精确实现目标的三维位姿的线性重建。实验表明,该算法快速高效,误差性能良好,抗噪能力较强。更多还原

【Abstract】 Based on the principle that the affine coordinate of a three-dimensional point is unchanged under rotation and translation trans-formation,and is also unchanged under the coordinate transformation from the computer coordinate system to the image coordinate system,a new algorithm to linearly and exactly reconstruct the 3D pose of the imaged target from its single-view.The algorithm needs at least four points to get the solution.The theoretical analysis and the experiments have demonstrated that the suggested algorithm is fast,exact,effi-cient and rather robust against noise.更多还原
