第1步:所需材料

跳跃Motion支持Python,Java,C ++,C#,Javascript。在本教程中,我们将使用Java。

因此,在开始制作程序之前,我们需要查看此构建所需的材料:

1。飞跃运动控制器(在此处购买)

2。面向Java开发人员的Eclipse IDE(在此处下载)

3。 Leap Motion设置文件(在此处下载)

4。 Leap Motion SDK(在此处下载)

5。 Java SE 7(在此处下载)(下载JDK和JRE )

( * Leap Motion库仅适用于Java 6或Java 7 )

如果您不知道如何设置eclipse,那么我推荐此Java系列入门教程:在此处观看

好,现在让我们转到涉及的步骤创建程序。

步骤2:软件设置

JAVA

JAVA

JAVA

JAVA

跳跃运动支持多种编程语言,例如C ++,C#,Python,Java和Javascript。

在本教程中,我们将使用Java进行编程。

初始设置:

1。首先转到https://www.leapmotion.com/setup并下载Leap Motion设置文件,然后安装该应用程序。它会安装所有内容,以将the动控制器连接到您的计算机。

2。接下来转到https://developer.leapmotion.com/(开发人员门户)并创建一个帐户。然后下载Leap Motion SDK。

3。然后将zip文件中的所有文件提取到您选择的任何文件夹中。

配置类路径:

在此本教程将使用面向Java开发人员的Eclipse IDE。

1。打开Eclipse,然后单击File》 New》 Java Project。

2。为项目命名,并确保将执行运行时环境JRE设置为Java SE 1.7,如图所示。

3。然后单击“下一步”,打开“库”选项卡,然后选择“添加外部JAR”并导航到先前提取的文件夹。

4。然后打开LeapSDK文件夹并转到libs文件夹并选择LeapJava.jar文件。

5。接下来,单击LeapJava.jar旁边的三角形下拉按钮,然后从“下拉菜单”中单击“本机库位置”,然后单击“编辑”,如图所示。

6。然后单击“外部文件夹”,然后导航到LeapSDK文件夹》 lib》,然后根据您的操作系统选择 x64 或 x86 文件夹,然后单击“确定”,然后单击“完成”。

我们现在在我们的项目中安装了LeapMotion,现在开始进行一些编码!

第3步:跳跃运动监听器

JAVA

Now that we are done importing the libraries , let us start working on the project.

初始设置:

1。首先,我们需要在源文件夹中创建一个新类,单击项目文件夹旁边的三角形下拉箭头。

2。在您的项目文件夹中,右键单击src文件夹,转到new》,然后单击class创建一个新的Java类。

3。给班级起个名字,然后单击完成。

现在,让我们从代码开始:

1。首先,我们创建一个Leap Motion侦听器:(注意:导入必要的库),侦听的侦听器是何时将Jump Motion控制器连接到计算机的。

controller.enableGesture(Gesture.Type.TYPE_CIRCLE);

System.out.println(“Press Enter to quit.。.”);

try {

System.in.read();

} catch (IOException e) {

e.printStackTrace();

}

controller.removeListener(listener);

}

}

screenHeight = gd.getDisplayMode().getHeight();

System.out.println(“Screen Resolution: X: ” + screenWidth + “, H: ”

readyForControl = true;

try {

robot = new Robot();

robot.setAutoDelay(5);

} catch (AWTException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

步骤4:帧和手势数据

JAVA

跳跃运动帧数据,其中包括手势(圆形,捏,掌面朝下和所有其他手势)

跳跃运动有两个红外摄像机和三个红外LED。跳跃运动使用三个IR Led形成IR点图案,从而形成3D数据收集,IR相机拍摄称为帧的图片。帧从跳跃运动设备发送到计算机,我们可以对其进行编程。

跳跃运动使用复杂的数学分析图片和点定位,然后比较红外拍摄的两张图片的数据相机并使用两个2D表示形式获得3D表示形式。

跳跃运动设备以300 fps的速度捕获。然后,我们对发送到计算机的每个帧进行处理。

代码:

public void onFrame(Controller controller) {

Frame frame = controller.frame(); // The latest frame

// Frame previous = controller.frame(1); //The previous frame

// System.out.println(“Frame available”);

if (!iBoxGet) {

iBox = frame.interactionBox();

iBoxGet = true;

System.out.println(“Interaction box set!”);

}

// Pointable furthestFront = frame.pointables().frontmost();

Hand rightHand = frame.hands().rightmost();

Vector palmV = rightHand.palmVelocity();

// palmV.getY()

// + “, Z: ” + palmV.getZ());
