The factors influencing the measuring precision are also analyzed. Then  the algorithm is adopted to fit curves. Experimental results indicate that the singular value decomposition is very precise  for its error sum is 1.1102V  and the squared error is 2.8mV. Moreover  for phase angle measurement  measured six times in same direction  the squared error is 24 (1). The method based on SVD can satisfy the system precision requirements of curve-fitting north seeking systems. 2011 IEEE.   A new accurate and fast algorithm of sub-pixel image registration (EI CONFERENCE) 会议论文  OAI收割 2010 IEEE 10th International Conference on Signal Processing, ICSP2010, October 24, 2010 - October 28, 2010, Beijing, China 作者:  He B. 收藏  |  浏览/下载：32/0  |  提交时间：2013/03/25 In terms of large field view and multi-channel TDICCD remote sensing images  previous interpolation methods and curve fitting methods are not able to achieve the high accuracy and fast registration  and their noise immunity and robustness is not high. For that  this paper presents a more accurate and faster method  iterative pixel interpolation and surface fitting method. Firstly  the method uses the some overlapping pixels between multi-channel images. Secondly  the proposed technique  which is based on the maximization of the correlation coefficient function  combines an efficient pixel-moving interpolation scheme with surface fitting  which makes use of accurate interpolation calculation and fast surface fitting in the iterative process. Finally  the accuracy and speed of the algorithm is evaluated by sub-pixel registration of multi-channel images and comparison with other sorts of efficient methods. The experiment results show that the accuracy of the method reaches 0.01 pixels and it is 3 times faster than the interpolation method. In the registration of large field view and multi-channel TDICCD images  the method is accurate and fast  with greatly high stability  noise immunity and robustness. 2010 IEEE.   Graph fitting test method for the interpolation error of Moire fringe (EI CONFERENCE) 会议论文  OAI收割 9th International Conference on Electronic Measurement and Instruments, ICEMI 2009, August 16, 2009 - August 19, 2009, Beijing, China 作者:  Sun Y.;  Sun Y. 收藏  |  浏览/下载：42/0  |  提交时间：2013/03/25 In order to realize the fast test for the interpolation error  the graph fitting test method for the interpolation error of Moire fringe is put forward in this paper. Firstly  the triangular wave Moire fringe photoelectric signal of the encoder whose phase difference is 90 are sampled to get the Lissajous graph of the two signals. Secondly  the single wave represented by the founded subsection function is used to fit the practical Moire fringe Lissajous graph. Then  the fitting result is tested to verify whether it satisfies the accuracy requirement. Lastly  the founded subsection function instead of the practical wave function is used to calculate the interpolation error. Using the graph fitting method to sample the Moire fringe single of 15-bits photoelectric encoder to get the interpolation error curve  the tested maximum interpolation error is 70" and the minimum error is - 69". Comparing with the interpolation error which is received from traditional test method  the change trend of the interpolation error curve is similar  and peak-peak value is almost equality. The results of experiment indicate that: the equipment is convenient and the examination method is efficient and feasible. The measure speed is fast and the manifestation result is intuitionistic. The system can be used in the working field. The method can avoid the speed influence and realize the dynamic interpolation error measure  which is significant for the research of encoder's dynamic accuracy characteristics. 2009 IEEE.   Robust LM algorithm and its application in satellite image geometric correction 会议论文  OAI收割 29th Asian Conference on Remote Sensing 2008, ACRS 2008,, Colombo, Sri lanka, November 10, 2008 - November 14,2008 Chen, Pengshan; Jiao, Weili; Jia, Xiupeng; Wang, Wei 收藏  |  浏览/下载：22/0  |  提交时间：2014/12/07 Geometry  Algorithms  Curve fitting  Newton-Raphson method  Remote sensing  Statistics
