基于证据理论的虚拟力机器人网络控制

将网络与机器人相连,延伸网络的应用领域,可以实现价格低廉的远程监视与操作,而远程控制成功实现的关键在于信息的正确获得。利用Dempster-Shafer对六个超声波传感器所获取的距离信息进行融合,而后连同速度信息提供给弹簧-阻尼器系统以构建虚拟力;力的信息通过编程映射到游戏杆上,变成操纵方向的约束力。通过采用微软公司的带有力反馈的操纵杆作为力觉提示装置控制移动机器人在结构化环境下顺利运行,验证了虚拟力信息获取方法的有效性。

关于P3P问题解的唯一性条件的几点讨论

P3P问题的多解现象使其应用受到了限制 ,前人的研究结果对布置控制点和摄像机没有太大的指导意义 .该文作者采用了与前人不同的研究方法 ,发现 3个控制点构成等腰三角形时 ,在空间可以找到一些区域 ,当摄像机在这些区域中时 ,可以唯一地求出所构成的P3P问题的真实解 .同时 ,该文的研究结果又对P3P问题在实际应用中布置控制点和摄像机的位置具有指导意义 .

非自喷层测试及评价解释技术研究与应用

Now low porosity and low permeability reservoir is one of the main targets of exploration for the onshore oilfields of China. Most of the reservoirs are none flowing because of bad formation percolation condition, poor gas oil ratio , low formation pressure coefficient and other factors. In the recent years, a number of domestic oilfields have carried out some research work and achieved some success on oil testing and production technology in such formation. But by now, there is still no systematic and mature technology, particularly testing technology in none flowing formation is still needed further study. Based on study the key problem of well testing and interpretation technology in none flowing formation, solve the important problems in well testing technology, continuously improve and innovate geological information acquisition technology for none flowing reservoir, accurately acquire boundary information and evaluate reservoir flow characteristics. Its wide application remarkable result has shown. The main results and cognitions obtained from research are as follows: 1. This new technology research results help solve the occurrent problems in well testing process for none flowing formations, such as small investigation radius, poor representative of interpretation results from the poor data, low level application of interpretation results. This new technology helps create favorable conditions for early precise reservoir evaluation and reduction of the risk of exploration. 2. The technological difficulties for none flowing well testing are successfully solved by using none flowing formation combined mechanical tool string .This method has been proved by its applications to be able to improve the efficiency of the testing and the quantity of the acquired test data ,and so as to enhance the application of the interpretation results of the test in development of oil fields. 3. The application of the rotary formation tester, selective test valve, well testing string and their allier tools help to resolve problems such as the operation of opening and shutting-in the well under different well conditions, to broaden the scope of well test technology for none flowing formations. 4. Refined Testing Technique for production Wells has greatly shortened the testing dwration and improved the efficiency and accuracy of operation, enriched test results, and at the same time created conditions for conducting multi-well interference well testing.
