结合摄像头使用，用于手部位置跟踪，精准度非常高，另可以识别六种手势。其手位跟踪模块可作为手势识别软件的一个组成部分，内含非常详细的说明文档。编译该代码，需要 OpenCV 0.97 或更高版本的支持。在Windows下的编译顺序为cubicles工程、handvu工程，之后根据视频数据来源要求编译其他代码。建议使用 Visual Studio 2003 ，如果需要编译 DirectX 相关模块，则请安装 DirectX SDK 9.0 或更高版本。-Combination of camera to use for hand position tracking, accuracy is very high, and the other six kinds of gestures can be identified. Digital tracking of their hand gesture recognition module can be used as an integral part of software, including a very detailed documentation. Compile the code, the need for OpenCV 0.97 or later support. Compiler in Windows under the order of cubicles works, handvu works, after the source of video data in accordance with the requirements of other code compiler. Recommend the use of Visual Studio 2003, if you need to compile the relevant modules DirectX, install DirectX SDK 9.0 or later.
