摘要

为了有效地实现相机自标定，本文提出了一种基于非刚体轨迹基的线性自标定方法，该方法利用了非刚体的运动轨迹构成一个低维子空间，并且该低维子空间的基可以由一组正交小波基线性表示的特性，线性地实现相机的自标定.由于该正交小波基可以事先定义，因此求解的未知数大大减少，而且使传统的相机自标定问题转化为线性求解问题，提高了算法的鲁棒性.模拟实验和真实实验数据结果表明，该方法能够有效地实现相机的自标定.

Abstract

To calibrate the camera

a linear camera self-calibration method based on non-rigid trajectory basis is presented in this paper.Based on the fact that the trajectories of non-rigid span a low subspace which can be spanned by an orthogonality wavelet basis

the camera self-calibration can be linearly realized.Because the wavelet basis can be predefined

the solved parameters are deduced and the camera self-calibration becomes a linear optimal problem

which can improve the robustness of the algorithm.The experiments of both simulation and real data show that the presented method can efficiently realize the camera self-calibration.
