OpenFrameworks + kinect + Android项目源码

OpenFrameworks + kinect + Android项目源码下载

The SIProp project‘s members finised to make “OpenFrameworks x kinectx Android” Development Environment and to run it on Android(armadillo & beagleboard).

Special Thanks:
We used those OSSs. Thank you for great works!

How to make:
1.Setup ofxAndroid’s Development Environment
Please refer to the following site:
ofxAndroid setup manual
If you can read Japanese & want to setup it on Windows, you should refer to this site.

2.Merge ofxKinect to ofxAndroid
2-1.Download & Setup to Eclipse
Please download soruce code from the following site:

Next, Copy [ofxKinect directory]/src/ofxKinect/ to [ofxAndroid directory]/addons/ .
Final, Add include path to Eclipse’s “(ofxAndroid’s)addons” project.
Please run Eclipse and add the folloing place & path:

Place: Properties -> C/C++ General -> Pths and Symbols -> Includes tab(GNU C++)

Path: [ofxAndroid directory]/addons/src/ofxKinect/src/

2-2.Fix compile error

If ofxAndroid doesn’t have ofxThread::waitForThread(bool) function.

Please add the following source:

[ofxAndroid directory]/addons/ofxThread/src/ofxThread.h

void waitForThread(bool stop = true);

[ofxAndroid directory]/addons/ofxThread/src/ofxThread.c

void ofxThread::waitForThread(bool stop){

if (threadRunning){

// Reset the thread state


threadRunning = false;

if(verbose)printf(“ofxThread: stopping thread/n”);

if(verbose)printf(“ofxThread: waiting for thread to stop/n”);

// Wait for the thread to finish

#ifdef TARGET_WIN32

WaitForSingleObject(myThread, INFINITE);



if(pthread_self()==myThread) printf(“ofxThread: error, waitForThread should only be called from outside the thread”);

pthread_join(myThread, NULL);


if(verbose)printf(“ofxThread: thread stopped/n”);

myThread = NULL;


if(verbose)printf(“ofxThread: thread already stopped/n”);



2-3.Do customize source code for Android

Please remove the following code in ofxKinect::threadedFunction() function:


Please add the following code in [ofxKinect directory]/libs/lubusb/io.c file:

#define TIMESPEC_TO_TIMEVAL(tv, ts) /

do { /

(tv)->tv_sec = (ts)->tv_sec; /

(tv)->tv_usec = (ts)->tv_nsec / 1000; /

} while (0)

2-4.Create your application project

Please choose sample programs from the following directory:

[ofxAndroid directory]/apps/androidExamples/

And copy it to the following directory:

[NDK directory]/apps/

Final, export this project on Eclipse.

2-5.Build project

You must build JNI at first.

You execute the following commands:

cd [NDK directory]/apps/[your app directory]

[NDK directory]/ndk-build -B

And, you build android application on Eclipse.

*If you don’t know how to use ofxKinect framework, please refer to “[ofxKinect directory]/src/testApp.cpp”.

3.Change Android’s configuration

Please add the following line to init.rc:

mount usbfs none /proc/bus/usb -o devmode=0666

4.Upgrade Android’s kernel

libusb MUST neet “USB FS”. And Kinect MUST neet “High Speed USB(USB2.0)”.

Therefore, you check the following kernel options:





If your device can not draw normal Z-camera image and RGB-camera image, you MUST need to build optimized kernel & userland.

I used the following optimization option for building kernel, userland & “OpenFrameworks x kinect x Android”.
