查询词典 frame of reference

In view of the demand of computerized eye-glasses-wearing system, an approach to match two dimensional (2D) human head images with 3D glasses frame graphics in 3D space has been proposed. First, the operator points out three or six key points, which are used to locate 3D eye-glasses frame, on the human face image displayed on the computer screen interactively.

论文针对计算机化眼镜配戴系统的要求，提出了一种在三维空间匹配二维人头图象和三维眼镜图形的方法，即通过人机交互方法，由操作者在显示于计算机屏幕上的二维人头图象上，指出确定三维眼镜位置的三个或六个关键点的二维坐标及其三维对应点，从而可以近似求出人面朝向及视点坐标，再用相应位置上的三维通用人头图形替换二维人面图象，计算人面和眼镜间的遮挡关系并显示，从而完成二者的空间匹配。

One or both of transmit and receive aperture controls may include preventing some element of the transducer array from transmitting or receiving, calculating weighting apodizations to combine with standard apodizations for each frame, or determining an aperture size based on an f-number for the transducer array for each frame.

发射和接收孔径控制中的一个或二者可以包括：阻止换能器阵列中的某个元件进行发射或接收，针对每一帧计算加权变迹以将其和标准变迹相组合，或者针对每一帧根据换能器阵列的F数来确定孔径尺寸。

Below we discuss the case of rotating frame in which the fictitious force depends on the position in the frame.

在后面我们还要讨论转动参照系的情况，在那种情况下，虚设力与物体在参照系中的位置有关。

It is called Frame Response, and it lets you adjust the speed of frame delivery from the buffer.

这就是所谓框架反应，它让你调整帧从缓冲区传输速度。

As for frame buffer access, the embedded compression for frame buffer access is considered in Part III.

而在框架缓冲器存取方面，针对框架缓冲器存取的嵌入式压缩则在第三部分中做考虑。

Rame 1 is in the frame buffer, and 2/3 of frame 2 are drawn in the back buffer.

PS50的例子。第一桢在显示缓冲，第二桢的2/3在后备缓冲。

With the constant development of manufacture technics of the CMOS image sensor, the resolution and frame frequency improve constantly too, which makes the rate of communication between camera and frame grabber become more important.

摘要随着CMOS图像传感器制造工艺的不断提高，数字相机的分辨率和帧频也不断提高，这使得相机和图像采集卡之间的通信速率变的异常重要。

Upon command from software, the frame grabber waits for the beginning of the next frame, as indicated by the vertical sync pulses.

由来自软件的指令之下，核心等候下一个体格的开始，如垂直的同步脉冲所指出。

First, we have discussed the designing fundamental of Integrated Effectiveness Evaluation Index System and presented the basic structure frame of Integrated Effectiveness Evaluation Index; thus, the model index frame of Integrated Effectiveness Evaluation was constructed to the Weapon System with Missile and Gun.

首先，通过对弹炮结合系统参数结构模型的分析，探讨综合效能评估指标体系的设计原则，并提出弹炮结合系统综合效能评估指标的基本结构和体系；接着，在此基础上建立弹炮结合系统综合效能评估的模型指标框架。

Frame relay voice compression capabilities have increased along with the development of the frame relay technology.

帧中继话音压缩功能随帧中继技术的发展而得到增强。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.

我们对在一个争夺日益激烈省的可能性。
