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.   Research on the torque characteristic of disc micromotor on axial magnetic field (EI CONFERENCE) 会议论文  OAI收割 2012 2nd International Conference on Consumer Electronics, Communications and Networks, CECNet 2012, April 21, 2012 - April 23, 2012, Three Gorges, China Liu B. 收藏  |  浏览/下载：53/0  |  提交时间：2013/03/25 In order to increase the electromagnetic torque density of micromotor with axial magnetic field  numerical analysis of permanent magnetic field and electromagnetic torque were deduced and the key factors of increasing torque density of micromotor was obtained. The numerical analysis of three-dimensional magnetic field in air gap produced by spliced sector permanent magnetic poles is done  and the way of improving flux density and permanent magnet use efficiency are given through investigating the influence of magnet thickness  height of air gap and pole interval rate and other parameters to air gap flux density and leakage flux. Based on the test of axial magnetic field and torque characteristic of micromotor  the analysis of micromotor magnetic field and calculation of torque are verified  meanwhile using the plane stator with 0.7mm thickness assemble micromotor having minimum air gap height of 1mm and its torque constant up to 3.8mNm/A. 2012 IEEE.   Global structure of Riemann solutions to a system of two-dimensional hyperbolic conservation laws 期刊论文  OAI收割 NONLINEAR ANALYSIS-THEORY METHODS & APPLICATIONS, 2011, 卷号: 74, 期号: 14, 页码: 4754-4770 作者:  Shen, Chun;  Sun, Meina;  Wang, Zhen 收藏  |  浏览/下载：29/0  |  提交时间：2015/06/25 Two-dimensional conservation laws  Riemann problems  Global structure of solutions  Generalized characteristic analysis  Delta shock wave   A real-time two-dimensional correlation speed measurement based on image (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China 作者:  Yu L. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 In order to implement two-dimensional moving object's non-contact and real-time speed measurement  in this paper  wc proposed a new method which was based on the characteristic of FPGA and a real-time two-dimensional correlation speed measurement was proposed on image processing using high speed CMOS shown in figure 1. Experimental installation was shown in figure 2  a cardboard with images which was fixed in electric control movement device was moving to simulate moving object  the CMOS image sensor gathered image signals of the cardboard and the image signals was output to FPGA after a serials pretreatment such as binaryzation etc. Logical operation insteaded mathematical operation on FPGA to implement two frames image's cross-correlation operations as the formula (10) in this paper  and finally calculate the two-dimensional velocity. Through experiment result of table 1 we drawn an conclusion the accurarcy of the method in this paper was less than 1 pixel and the method can be used at a certain speed ranges of two-dimensional  real-time speed measurement. 2010 IEEE.
