The gestures of real palm that obtained by position tracker are mapped to the gestures of virtual palm in the virtual reality environment by data mapping and transfer matrixes.

通过位置跟踪器获取操作者手掌的位姿数据，采用数据分解和矩阵变换的方法将其映射为虚拟手掌在虚拟现实环境中的位姿，实现了对虚拟手的准确控制。

When a Tracker is closed, the application typically moves or resizes the associated control to match the position and size of the Tracker.

在关闭Tracker时，应用程序通常就把相关控件移动或修改尺寸到与Tracker匹配的位置和尺寸。

Estimated positions will be generated by interpolating the tracker position in-between nearby keyed or tracked positions.

估计位置将由插值生成的跟踪位置中间的键控或跟踪位置附近。

Having a tracking window that is too large compared to the feature it is tracking may cause the tracker to fail, or the tracker position to drift over multiple frames.

有一个跟踪窗口太大而功能是跟踪可能会导致跟踪失败，或跟踪器在多个帧的位置漂移。

In order to find trace quickly, this paper introduces a real-time method with a set of equidistant linear array sensor to detect relative cross state and absolute position between trace and tracker.

提出一种用等间距排列的一组线阵状传感器对迹线的绝对位置和迹线与跟踪装置的相对交越变化情况进行实时检测的方法来达到快速寻迹的目的。

Using the CCD star tracker as the ships position measuring instrument is considered much for its high positioning accuracy. no position accumulated error, fast and intelligent work.

CCD星体跟踪器作为舰船位置测量仪器，因其定位精度高、无位置积累误差、快速和智能化工作而受到重视。

The position of the face can initialize the parameters of face tracker to realize fast face tracking and video object coding.

用检测到的人脸位置来初始化跟踪算法实现快速人脸跟踪；

Offset degree between trace and tracker can be directly determined by detecting absolute position of trace.

通过对迹线绝对位置的检测可以直接判断出跟踪装置与迹线的偏离程度。

This is necessary when a tracker is occluded by another moving object, or when the tracker should move out of bounds but instead is tracked to an incorrect position.

这是必要的当一个跟踪点阻挡被另一个移动的物体时，或当跟踪应该搬出界限而是被跟踪到一个不正确的位置。

The spacecraft worked for eight-and-a-half years before its star tracker failed and it could no-longer work out its position and point correctly.

在其星象跟踪仪出故障导致其自身再也不能准确计算出方位和坐标点之前，飞船整整工作了八年半。
