下载安装

下载地址

tip安装的时候记住安装的路径，该安装包无法自定义安装，默认路径为系统盘\Program Files (x86)

点击exe安装完成之后，可以看到右下角状态栏里出现leap motion的小图标，绿色表示连接成功

tip如果出现绿色闪烁，可尝试着右键-观察器，查看有无图像生成。

安装完成之后，也可以尝试着打开SDK里的App Home，可以看到多款demo~

环境配置

1.配置系统的环境变量，如下添加

tip:这里要注意，尽管你的电脑是64位的，但由于软件的框架是x86的，所以还是要链接到x86的，同时环境变量配置完成后电脑要注销或重启，相关配置才会生效。

2.配置visual studio(2010,2012,2013)

首先建立空项目

右键项目属性，分别如下配置

至此配置完成

代码测试

官方所给环境测试代码

#include 
   
    #include 
    
     #include "Leap.h"using namespace Leap;int main(int argc, char** argv) {    std::cout << "Hello Leap motion!!!" << std::endl;    // Keep this process running until Enter is pressed    std::cout << "Press Enter to quit..." << std::endl;    std::cin.get();    return 0;}
    
   

若环境配置无误，则如下图所示

功能测试代码

      #include 
    
       #include "Leap.h"  using namespace Leap;class SampleListener : public Listener {public:    virtual void onInit(const Controller&);    virtual void onConnect(const Controller&);    virtual void onDisconnect(const Controller&);    virtual void onExit(const Controller&);    virtual void onFrame(const Controller&);    virtual void onFocusGained(const Controller&);    virtual void onFocusLost(const Controller&);    virtual void onDeviceChange(const Controller&);    virtual void onServiceConnect(const Controller&);    virtual void onServiceDisconnect(const Controller&);    virtual void onServiceChange(const Controller&);    virtual void onDeviceFailure(const Controller&);    virtual void onLogMessage(const Controller&, MessageSeverity severity, int64_t timestamp, const char* msg);};const std::string fingerNames[] = { "Thumb", "Index", "Middle", "Ring", "Pinky" };const std::string boneNames[] = { "Metacarpal", "Proximal", "Middle", "Distal" };void SampleListener::onInit(const Controller& controller) {    std::cout << "Initialized" << std::endl;}void SampleListener::onConnect(const Controller& controller) {    std::cout << "Connected" << std::endl;}void SampleListener::onDisconnect(const Controller& controller) {    // Note: not dispatched when running in a debugger.      std::cout << "Disconnected" << std::endl;}void SampleListener::onExit(const Controller& controller) {    std::cout << "Exited" << std::endl;}void SampleListener::onFrame(const Controller& controller) {    // Get the most recent frame and report some basic information      const Frame frame = controller.frame();    std::cout << "Frame id: " << frame.id()        << ", timestamp: " << frame.timestamp()        << ", hands: " << frame.hands().count()        << ", extended fingers: " << frame.fingers().extended().count() << std::endl;    HandList hands = frame.hands();    for (HandList::const_iterator hl = hands.begin(); hl != hands.end(); ++hl) {        // Get the first hand          const Hand hand = *hl;        std::string handType = hand.isLeft() ?

运行后，在leap motion上伸出手，输出即有相应的反应。

几个常见的错误

1.leap motion程序运行后出现无法解析的外部错误

可能的原因：在配置时选择了x64，改为x86即可

2.leap motion程序运行编译无错，在结果页面出现报错提示

配置完环境变量后未重启或注销，环境变量未生效
