	详细描述

PTI 为满足高端客户的需求，推出了精度更高，采样速率更快的实时全身动作捕捉系统Visualeyez™ VZ4000。

新推出的 Visualeyez™ VZ4000 动感器除了具备以往的功能外，它的采样速率更快，达到每秒钟4300次(详见系统特点)。另外，VZ4000 使用了更好的光学滤镜，可滤掉更多的环境噪声提高信噪比。光标控制模块(TCM)具有更好的电磁兼容性。

VZ4000 的新性能使其在应用和部件开发中扮演着重要的角色。总的来看，VZ4000 系统拥有更高的技术指标和稳定的性能，所有软件向下兼容。具有热循环复合碳纤维和轻质合金外壳结构的 VZ4000 动感器能够保持永久的刻度精度和稳定性。铝合金的三脚架同时也是一个运输保护箱。

	Description

For motion capture users who require good performance and full body motion capture, this predecessor of the VZ4000 may already provide sufficient capabilities for the purpose. This series of trackers has proven itself to deliver real-time top quality motion data for projects ranging from computer animation for film and video games to scientific research．

The processed data is normally displayed graphically in real time on the friendly VZSoft™ graphical user interface (GUI) and exported through VZSoft™ plugins, in real time, to many industry standard animation and scientific applications, including:

LabVIEW
MATLAB
Autodesk Motion Builder
Visual3D

Each VZ3000 tracker features a rigid carbon composite construction for permanent calibration stability, with a lightweight aluminum shell. The elegantly- designed aluminum tripod also doubles as a heavy duty protective case during tracker transportation.

The tracker performs four primary functions:

Receives and executes the user commands specified via the VZSoft™ GUI
Controls the intelligent TCMs (Target Control Modules) to turn on the LED markers in the specified sequence
Senses the marker lights and computes the marker XYZ coordinates
Outputs the coordinates to the host device synchronously
