摘要：

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. © 2017, Chinese Institute of Electronics. All right reserved.
