Keyword单目视觉 P3p 位姿测量精度 标定参数误差
Abstract本文以提高基于模型的单目视觉位姿测量系统的测量精度为目标,分析了摄像机标定参数误差与位姿测量精度的关系,得到如下结论:测量距离方向位置精度主要受焦比误差和光轴方向平移量误差的影响;姿态角精度主要受主点误差和外参旋转角误差的影响。该结论对视觉位姿测量系统的工程应用具有一定的指导意义。
Other AbstractTo enhance the measuring accuracy of monocular vision pose estimation system which is based on a model in the real project, the relation between the error of camera parameters and the error of pose measurement has been analyzed. It has been established that the position accuracy in the direction of measuring distance is strongly influenced by the error of focal ratio and translation error in the direction of the optical axes. On the other hand, the attitude accuracy is mainly influenced by the error of principle point and the error of rotation angle calibrated. The conclusion provides some reference for engineering application of the vision pose measurement system.
