面向对象知识库系统CAOBS/V1.2的可视化查询子系统 总被引:3,自引:1,他引:3
面向对象知识库系统CAOBS/V1.2的用户界面是一个可视化知识查询子系统,它包括一个灵活、直观、方便的可视知识查询语言(VKQL)和一个知识库浏览编辑器。利用该可视化查询语言,用户可以通过构造查询图来表达查询要求,并最终实现查询功能。VKQL吸收了国际上现有的几种可视查询语言的优点,具有较强的查询功能,使用方便。文中介绍了VKQL的设计思想和实现技术,在最后一节将VKQL与同类查询语言进行了对比 相似文献

Virtual reality technology has been widely used in the fields of aerospace, robotics remote operation and biology medicine and so on. Panoramic image mosaic is one of the very important parts. Since photographs taken by the ordinary camera may appear distorted, overlapping and tilting, we propose a wide mosaic algorithm used in the projection transformation in this paper. The algorithm first uses the Harris operator to extract corners, adopting the improved corner response function for avoiding the randomness of k value. Then fast RANSAC method is used to match the images approximately, and the cross-correlation method of gray window as the center of feature points is used to the redundant feature points for further exact match. And then it need solve the model transformation parameters between two images according to these corners information and obtain the projection transformation matrix. Finally, the application of image morphing technique is for reconstructing the image having spatial transform, the result of which are carried on stitching seamlessly with another source image. Experimental results show that the algorithm is effective to achieve a good mosaic. 相似文献

A decentralized controller design is presented for multirate sampled-data systems, where stability and input-output performance are considered in terms of continuous-time signals. The design procedure consists of analysis for the overall system and controller synthesis for individual subsystems. For the subsystem designs, a unique technique of removing lifting operation which is used in the analysis is proposed. Robust performance and robust stability in terms of continuous-time signals can be achieved by using the proposed design. A numerical example shows that the design method results in satisfactory controllers which guarantee closed-loop stability and performance in continuous time. 相似文献
