虚拟

The current 3D picture technology can mainly be categorized into two types: 3D cartoon technology and virtual-reality technology—new developments that visualize virtual reality and imagination and are superb in terms of timeliness and interactiveness.

三维动画与虚拟现实技术是目前三维图形、图像表现技术中颇为典型的代表性技术。三维动画技术和虚拟现实技术作为对模拟真实和想象世界进行视觉再现的一种高端图形、图像技术，在实时性、交互性方面的优势，是其它同类技术所无法比拟的。

Based on the introduction of virtual instrument and LabVIEW, the overall design of virtual signal oscilloscopes analyzer was put forward in this paper, and the software design of different parts of the analyzer was also introduced in detail.

摘 要：本文在介绍了虚拟仪器与LabVIEW的基础上，提出了虚拟信号示波分析仪的总体设计方案，并以此为基础较详细地介绍了该仪器的各个部分的软件设计。

On this basis, empirically studies the incoordination between fictitious economy and real economy. At last, probes into the government intervention under the condition of incoordination of fictitious economy and real economy.

在此基础上，对虚拟经济与实体经济的非协调发展进行了实证研究，最后探讨了虚拟经济与实体经济非协调发展下的政府干预。

A reverse measurement system about the data collecting of 2-D object edge based on machine vision is discussed,in order to realize digital data input of the dimensions of 2-D object complex edge. This system realized calibration in large scene by virtual grid calibration method, and advanced the precision of system by using double CCD cameras. It realized data mergence by setting up referencer of regular shape. Some methods were put forward to realize graphics vectorization such as using eight-chain code difference to search for the turning points, and using change-length subjunctive beeline to distinguish linetype. The output data use the general DXF document format to connect the software of CAD. Research indicated that this system can be applied in reverse measurement to the dimensions of 2-D object complex edge.

对机器视觉二维反求测量系统进行了研究，以实现二维复杂平面边缘尺寸的数字化录入；采用虚拟网格技术实现大场景下的测量标定；利用双CCD分区域获取图象，通过设置规则参照物、数据拼接等数据处理提高测量精度；提出了利用8-链码的&链差&确定转折点，用&变长度虚拟直线&判断线型实现图形矢量化的方法；数据输出采用通用的DXF文件格式实现与CAD软件的接口；研究结果表明，该系统能够应用于二维复杂平面边缘的反求测量。

The heart of this algorithm is to track at least four fiducial points from frame to frame that construct the affine frame, thus the occlusion contours between virtual and real objects can be reconstructed and reprojected. Further, each contour is labeled as being "behind" or "in front of" in the first two frames, depending on whether it is in front of or behind the virtual object, so the occlusion is resolved.

该算法的核心是在每一帧图像中追踪至少四个基准点，构成仿射基，进而对虚拟物体与真实物体之间的遮挡轮廓进行重建和重投影，且在前两帧图像中交互指定这些阻挡轮廓相对于虚拟物体的前后位置，从而解决了扩充现实的阻挡问题。

To solve these problems, virtual reality techniques are brought into CAD community, which yields the socalled VR-CAD system.

为解决这些问题，研究人员将虚拟现实技术引入到CAD系统中，基于虚拟现实的CAD系统应运而生。

A most innovative and successful project was the promotion in 2006 of a virtual course on urban land regularization, aimed at about 900 people from several professional backgrounds and institutional positions, and from all over Brazil. The three-month course was promoted jointly by the Ministry of Cities and the Virtual Department of Minas Gerais Catholic University, and it was sponsored by the Cities Alliance.

最为创新和成功的方案是2006城市用地规划虚拟方案的提升，这是由全巴西大约900个有专业背景和学术职位的人所建立的。3个月的进程带动了城市部门和米纳斯吉拉斯教会大学虚拟学院的共同进步，并且受到了城市联合会的赞助。
