Extracts and the match based on two-dimensional picture characteristic point is the 3D reconstruction technology core. Taking binocular stereoscopic vision theory as a foundation  through extracts the characteristics of SURF based on the multi-scale analysis  this feature has specific scale reproducibility  put the epipolar constraints and disparity constraints as conditions judgement to specific screening  it is greatly reduced the search range. The experiment use the matching method for three different actual scenes  the results shows that the method can enhance the image matching speed and precision  and can get more precise dense parallax  used for reconstruction complete scene. 2012 IEEE.   An autostereoscopic projecting system based on parallax barrier and lenticular sheets (EI CONFERENCE) 会议论文  OAI收割 2nd International Conference on Multimedia Technology, ICMT 2011, July 26, 2011 - July 28, 2011, Hangzhou, China Kong L.; Jin G.; Zhong X. 收藏  |  浏览/下载：17/0  |  提交时间：2013/03/25 In order to realize autostereoscopic 3D projecting display with higher brightness and larger size  a technique of autostereoscopic 3D projecting using parallax barriers and lenticular sheets is proposed.The parameter design of lenticular sheets and parallax barriers is investigated.First  projection distance of projector array is confirmed according to eye's resolution  then the strips' character of lenticular sheets is analysed by zemax in four-view situation  thickness and parameters of strips of lenticular sheets are confirmed. Finally  the width of slit and pitch and viewing distance and etc of parallax barriers are confirmed according to parameters of strips of lenticular sheets.Data analysis indicate that the brightness of our four-view image is increased three times because of using lenticular sheets instead of parallax barriers comparing with the autostereoscopic 3D projector using two parallax barriers plates.Parameters design of parallax barriers and lenticular sheets are finished  the feasibility and advantages of the 3D display of projecting are confirmed theoretically. 2011 IEEE.   基于多特征融合的鲁棒场景重建 学位论文  OAI收割 工学硕士, 中国科学院自动化研究所: 中国科学院研究生院, 2010 白沁洵 收藏  |  浏览/下载：91/0  |  提交时间：2015/09/02 三维重建  图像分割  主成分分析  3D reconstruction  image segmentation  principal component analysis   Research on station mode for attitude determination of multiple targets (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Computational and Information Sciences, ICCIS2010, December 17, 2010 - December 19, 2010, Chengdu, Sichuan, China 作者:  Zhao L.;  Wang J.;  Li M. 收藏  |  浏览/下载：38/0  |  提交时间：2013/03/25 A key problem of attitude determination system is how to locate CMOS cameras and deal with relations among them. In this paper  several kinds of multi-CMOS station mode are introduced. Fundamental principles and classification of station mode directly affect on measurement parameters of system. No matter what mode is designed  the ultimate goal is to extend Effective Viewing Field (EVF)  increase capture ratio of objects and increase measurement precision. Station mode introduced in this paper is made of CMOS cameras  because of low cost  high speed frame frequency and low power consumption  CMOS cameras were putted near from object tested. So sequences of image are legible  which are convenient for analysis of three dimensional(3D) attitude. 2010 IEEE.   Three-dimensional angle measurement based on auto-collimation and moire fringe (EI CONFERENCE) 会议论文  OAI收割 2008 International Conference on Optical Instruments and Technology: Optoelectronic Measurement Technology and Applications, November 16, 2008 - November 19, 2008, Beijing, China Cai S.; Liang S.; Qiao Y.-F. 收藏  |  浏览/下载：28/0  |  提交时间：2013/03/25 A method for small three-dimensional (3D) angle measurement based on auto-collimation and moire fringe is proposed and analyzed. A right-angle prism is used as the indicator of angle change. The inclined plane indicates the pitch and yaw angles and roll angle in indicated by the rib which is the intersection of two right-angle sides. Pitch and yaw angles measurement are implemented by auto-collimation based on reticule and roll angle measurement is measured based on moire fringe. Roll angle measurement is separated from pitch and yaw by using two light sources with different frequencies. Any small change of pitch and roll angles will induce the shift of the reticule image after reflecting by inclined plane. And any small roll angle will induce a change in moire fringe width that is generated by scale grating image which is reflected by the prism and index grating. The math model of this method is built up and error analysis is presented. The theoretical calculation results show that the proposed method is feasible and can achieve high accuracy. 2009 SPIE.
