SLAMBench for Android

This repository contains the Android version of SLAMBench. SLAMBench for Android uses the KinectFusion algorithm to evaluate the CPU (and the GPU) performance of mobile phones.

About the benchmark algorithm

KinectFusion is a Simultaneous Localization And Mapping algorithm (SLAM) and it uses an RGB-D sensor (like the XBox Kinect).

SLAM algorithms are used:

• to localize a camera in the scene it records, and
• to reconstruct the recorded scene.

RGB-D sensors are :

• a standard camera (RGB), and
• a depth camera (D) to get the distance between the camera and the visible points of the scene.

We are using the SLAMBench implementation (C++,OpenMP,OpenCL) of this algorithm, which itself is inspired from the KFusion implementation (CUDA only). SLAMBench is a framework which includes speed, accuracy and power measurement.

About the study

Many vendors include OpenCL in their mobile devices to use the GPUs for computation, and this provides opportunities for real-time vision applications. Vendors also started to integrate RGB-D sensor in their devices, we investigate if KinectFusion is a suitable solution for mobile devices with or without OpenCL.

About the configurations

KinectFusion can be parametrized, but its default configuration is too slow to run on any mobile phones (even the most powerful one). We are using custom configurations (called fast1 to fast4) which make possible to run KinectFusion on these mobile phones.

How to compile it

Well, there is no standard procedure yet, but here is a way...

Quick compilation

Just a make should work, but please read the preparation before.

Preparation

I prepared it on a clean Fedora 24 Workstation, and this is what I did first :

• Install** Java 1.8**, Python 2.7, GCC

  dnf install java-1.8.0-openjdk java-1.8.0-openjdk-devel 
  dnf install python
  dnf install gcc gcc-c++

• If you are running on a 64bit machine you will need to install 32bits dependencies.

  dnf install libstdc++-devel.i686 zlib.i686

• Install android-studio -- optional -- (https://developer.android.com/studio/index.html)

  wget https://dl.google.com/dl/android/studio/ide-zips/2.1.2.0/android-studio-ide-143.2915827-linux.zip
  unzip android-studio-ide-143.2915827-linux.zip
  mkdir -p ~/.local/Android/
  mv android-studio ~/.local/Android/android-studio
  ~/.local/Android/android-studio/bin/studio.sh

• Install Android SDK 22 (https://developer.android.com/studio/index.html) this includes then Android SDK Platform-tools , Android SDK Tools , SDK Platform Android 5.1.1 API 22, Android SDK Build-tools 22.0.1, Google APIs Android API 22, Android Support Repository

  wget https://dl.google.com/android/android-sdk_r24.4.1-linux.tgz
  tar xzf android-sdk_r24.4.1-linux.tgz
  mv android-sdk-linux ~/.local/Android/Sdk
  ~/.local/Android/Sdk/tools/android list sdk --all
  ~/.local/Android/Sdk/tools/android update sdk -u -a -t "platform-tools,tools,android-22,build-tools-22.0.1,extra-android-m2repository,addon-google_apis-google-22"   

• Install Android NDK r10e (https://developer.android.com/ndk/downloads/index.html)

  wget http://dl.google.com/android/repository/android-ndk-r10e-linux-x86_64.zip
  unzip android-ndk-r10e-linux-x86_64.zip
  mv android-ndk-r10e ~/.local/Android/android-ndk-r10e

Then you need to fix the absolute paths in ./local.properties:

echo "sdk.dir=/home/`whoami`/.local/Android/Sdk" > ./local.properties
echo "ndk.dir=/home/`whoami`/.local/Android/android-ndk-r10e" >> ./local.properties

Compilation

Just a make should work.

Installation

Once the apk is built, you can install it on a mobile phone using the following command :

adb install ./app/build/outputs/apk/app-debug.apk
