Following the previous article "The config of the kinect tutorial based on the qualcomm platform", this article will next introduce the running environment of kinect built on the android platform based on qualcomm.
I. OverviewThis tutorial is based on the qualcomm android platform to build kinect runtime environment, we use: OpenFramework+OpenNI+Kinect of android, where Kinect of android is a sub-project in the OpenFramework source code; the following is the specific construction steps.
Second, the hardware environment: Dragonboard 410c + Kinect
Figure 1 Dragonboard 410c
Figure 2 Kinect sensor
Third, the software environmentOpenFramework+OpenNI+Kinect of android, where Kinect of android is a sub-project of OpenFramework source code, my compilation environment is 64-bit ubuntu, the following describes the construction of each part in detail.
1.OpenNI
1.1. Building OpenNI 2.2:
1.1.1 Download the android ndk compilation tool:
Cd $HOME
Mkdir work
Cd work
Wget http://dl.google.com/android/ndk/android-ndk-r8e-linux-x86_64.tar.bz2
Tar -jxvf android-ndk-r8e-darwin-x86_64.tar.bz2
1.1.2. Download OpenNI2.2 from git:
Cd $HOME/work
Git clone https://github.com/OpenNI/OpenNI2.git
Cd OpenNI2
# Manually modify the PS1080.ini path
Vi ./Source/Drivers/PS1080/Sensor/XnSensor.cpp
#define XN_GLOBAL_CONFIG_FILE_NAME "PS1080.ini" -> #define XN_GLOBAL_CONFIG_FILE_NAME "/system/lib/PS1080.ini"
#Modify the OpenNI.ini path
Vi. /Source/Core/OniContext.cpp
staTIc const char* ONI_CONFIGURATION_FILE = "OpenNI.ini"->staTIc const char* ONI_CONFIGURATION_FILE = "/system/lib/OpenNI.ini";
Static const char* ONI_DEFAULT_DRIVERS_REPOSITORY = "OpenNI2" XN_FILE_DIR_SEP "Drivers" ->static const char* ONI_DEFAULT_DRIVERS_REPOSITORY = "/system/lib/";
1.1.3 Compiling OpenNI2.2:
Cd packaging
Python ReleaseVersion.py android
Cd Final
Tar -xvf OpenNI-android-2.2.tar
Cd OpenNI-android-2.2
Ls
EventBasedRead OpenNI.ini SimpleRead libOpenNI2.so libPSLink.so
MultipleStreamRead PS1080.ini libOniFile.so libPS1080.so libusb.so
# Push the following important library files to the Android directory
Adb push OpenNI.ini /system/lib/
Adb push PS1080.ini /system/lib/
Adb push libOpenNI2.so /system/lib/
Adb push libPS1080.so /system/lib/
Adb push libusb.so /system/lib/
Adb push libOniFile.so /system/lib/
Adb push libPSLink.so /system/lib/
Adb push SimpleRead /system/lib/
# Detect the operation of OpenNI:
Adb shell
Cd /system/lib/

2.OpenFramework 8.1
2.1. Download the openframework source code and build the build environment. For details, refer to http://openframeworks.cc/setup/android-eclipse/ for download configuration.
2.2. Download android NDK
Cd $HOME/work
Wget http://dl.google.com/android/ndk/android-ndk-r9d-darwin-x86_64.tar.bz2
Tar -jxvf android-ndk-r8d-darwin-x86_64.tar.bz2
2.2 Setting OpenFramework's paths.make
Vi libs/openFrameworksCompiled/project/android/paths.make
SDK_ROOT=$HOME/work/
NDK_ROOT=$HOME/work/android-ndk-r9d
2.3 Setting the library fie and make file of OpenNI include
Modify the "libs/openFrameworksCompiled/project/android/config.android.default.mk" file
ABIS_TO_COMPILE_RELEASE = armv5 armv7 neon — > ABIS_TO_COMPILE_RELEASE = armv5 armv7 neon x86

PLATFORM_HEADER_SEARCH_PATHS += "$HOME/work/OpenNI2/Include"
PLATFORM_LIBRARIES += OpenNI2
PLATFORM_LIBRARIES += OniFile
PLATFORM_LIBRARIES += PS1080
3.android application
