This method adopts a collimator tube that can be measured as a target fixed to the test table  and the target corresponds to the angular position of the test table. In the process of the table rotating  the camera will to keep track of the objective at a high speed. Due to the high sampling frequency of the high-speed camera  instantaneous angular rate of test table can be measured. With pixel subdivision technology  its measuring accuracy can be up to 0.02 pixels. We use this methods measured a low-speed test table's angular rate and analyzed the data. The error analysis shows when the rate of the test table is 0.20/s  the accuracy of the method can achieve 0.0220%. 2009 IEEE.   The quantitative evaluation on X3D-based ORGDM 会议论文  OAI收割 2009 WRI World Congress on Computer Science and Information Engineering, CSIE, Los Angeles, CA, United states, 2009 Chen; Yan-Rui1; 2; 3; Wang; Tao1; Xi1; Bai; Xu4 收藏  |  浏览/下载：20/0  |  提交时间：2011/08/23 Calculation efficiency - Case studies - Data models - Database research - File systems - Geo-spatial data - Laws of nature - Management style - Patial data model - Performance computing - Performance spaces - Professional models - Qualitative assessments - Quantitative analysis - Quantitative evaluation - Quantitative evaluation methods - X3D-based ORGDM   Quantative inversion based on hyperspectral data for soil salinization in the ecological corridor of tarim river, xinjiang,china 会议论文  OAI收割 2008 IEEE International Geoscience and Remote Sensing Symposium, Boston, MA, United states, 2008 Cun; Chang1; 2; Xi; Chen1; Anming; Bao1; Geping; Luo1 收藏  |  浏览/下载：13/0  |  提交时间：2011/08/23 Differential equations - Inverse problems - Problem solving - Regression analysis - Remote sensing - Rivers - Salinity measurement - Soils - Field sampling - Field test - Hyperion - HyperSpectral - Hyperspectral Data - Hyperspectral remote sensing - Key factors - Regression model - Sampling methods - Soil salinity - Soil salinization - Spectral estimation - Surface soil - Tarim river - Xinjiang   Karst rocky desertification information extraction with EO-1 Hyperion data 会议论文  OAI收割 International Conference on Earth Observation Data Processing and Analysis, ICEODPA,, Wuhan, China, December 28, 2008 - December 30,2008 Yue, Yuemin; Wang, Kelin; Zhang, Bing; Jiao, Quanjun; Yu, Yizun 收藏  |  浏览/下载：9/0  |  提交时间：2014/12/07 Landforms  Climatology  Data processing  Degradation  Ecosystems  Monte Carlo methods  Observatories  Remote sensing  Spectrum analysis  Substrates  Vegetation   Methods for integrated simulation of high-precision space optomechanical systems (EI CONFERENCE) 会议论文  OAI收割 3rd International Symposium on Advanced Optical Manufacturing and Testing Technologies, AOMATT 2007: Advanced Optical Manufacturing Technologies, July 8, 2007 - July 12, 2007, Chengdu, China Dong W.; Guang J.; Hong-bo Y. 收藏  |  浏览/下载：16/0  |  提交时间：2013/03/25 Each disciplinary has its own modeling and analysis tools to solve its own specific field problems. In order to achieve integrated simulation of high precision space optical systems and predict optical performance respective to the mechanical and thermal loads  data must pass through different analysis tools. Simulation tools used in the thermal  structural and optical design process and the relationship among them were first depicted and the integrated simulation methods were described in detail. Zernike polynomial fitting methods and interpolating approaches were also demonstrated. Because of the orthogonality of Zernike polynomials  it was not probably used in some situations such as noncircular apertures and discrete data  and the coupling of Zernike polynomial coefficients and other methods were also introduced in the paper. The toolkit OMTIA (Optical  Mechanical and Thermal Integrated Analyzer) based on the methods was developed  which appears as an indispensable tool for engineering practice.   Design of GPS/INS integrated navigation system based on multisensor information fusion (EI CONFERENCE) 会议论文  OAI收割 6th World Congress on Intelligent Control and Automation, WCICA 2006, June 21, 2006 - June 23, 2006, Dalian, China Chunmei H.; Yantao T.; Wanxin S.; Mao L. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 Two kinds of design methods of GPS/INS integrated navigation system are presented  that is GPS/INS integrative system and integrated navigation system based on information fusion. By analyzing mathematics model of the first system error  we found that inertia velocity error would cause code loop track error. Consequently  the pseudo range meterage error is interrelated with inertia velocity error  which is complex to calculate. If this relativity is ignored in the state equation and observation equation of this system  it must affect the estimated precision of the kalman filter and maybe the system is unstable. Therefore  the second integrated navigation method is introduced. It adopts information fusion  federal kalman filter and covariance. And consider the above pertinence to analyze the navigation performance of the integration system. Then it gives the flow of federal kalman filter algorithm. By analyzing  the conclusion is that velocity error of integrated navigation system drops from 0.5m/s to below 0.05m/s  and improves the precision and reliability of the navigation system effectively  well continuity and real-time capability. It provides an effective way for data analysis and process of fusion navigation system. 2006 IEEE.   Sensitivity of topography on insar data coregistration 会议论文  OAI收割 2004 Envisat and ERS Symposium, Salzburg, Austria, September 6, 2004 - September 10,2004 Huanyin, Yue; Hanssen, Ramon; Kianicka, Jan; Marinkovic, Peter; Van Leijen, Freek; Ketelaar, Gini Source 收藏  |  浏览/下载：12/0  |  提交时间：2014/12/07 Synthetic aperture radar  Correlation methods  Data acquisition  Error analysis  Geodetic satellites  Polynomials  Radar imaging  Sensitivity analysis   Deducing and analyzing the spectral characteristic of objects using EO-1 hyperion data 会议论文  OAI收割 2005 IEEE International Geoscience and Remote Sensing Symposium, IGARSS 2005,, Seoul, Korea, Republic of, July 25, 2005 - July 29,2005 Jiang, Xiaoguang; Tang, Lingli; Li, Caixing; Xi, Xiaohuan; Liu, Liang Source 收藏  |  浏览/下载：11/0  |  提交时间：2014/12/07 Remote sensing  Computational methods  Data reduction  Geostationary satellites  Image analysis  Spectroscopic analysis  Spectrum analyzers  Vegetation
