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.
