Springboard & OpenCV
Download as ppt, pdf1 like436 views
This document discusses setting up the Springboard platform and OpenCV for computer vision applications. It provides instructions for setting up the Springboard hardware with Android 4.0.3, downloading and building OpenCV for Android, and deploying OpenCV sample applications to the Springboard. Potential applications discussed include robotics, security, advertising and more.
Springboard & OpenCV
- 2. Outline ? Setup Springboard ? OpenCV for android ? Setup environment to build OpenCV for Android ? OpenCV build tricks ? Demo sample ? Springboard Robot ? Concept / Architecture ? Key point ? Usb-to-serial ? BT
- 3. Setup Springboard ? Introduction http://www.viaspringboard.com/products/via- vab-600-springboard-kit.html ? 800Mhz Arm Cortex-A9 Soc ? 1GB DDR3 SDRAM on board ? 4GB on board eMMC flash ? Mini-HDMI port/ USB 2.0 ? Ethernet ? Micro SD card reader on board
- 4. Setup Springboard with Android4.0.3 ? Requisition: ? Micro SD card 4GB above ? Download Android SW development package http://www.viaspringboard.com/via-vab-600- springboard-software-development-packages.html ? Extract ./bspinst, and .scriptcmd to SD card ? Insert SD card, and reboot springboard ? Reboot then enter firmware burning(~100%, blue background) ? Remove SD card from springboard ? Reboot and enter Android OS
- 6. OpenCV for Android ? OpenCV is a powerful open library for image processing and pattern recognition ? OpenCV for win, linux , processing and OpenCV for Android ? Download from : http://opencv.org/downloads.html ? Info: http://docs.opencv.org/doc/tutorials/introducti on/android_binary_package/O4A_SDK.html
- 7. Setup environment to build OpenCV for Android ? Require: ? JDK : http://www.oracle.com/technetwork/java/javase/downloads/j dk8-downloads-2133151.html ? Eclipse or ADT-bundle ? Eclipse is an IDE for programming C, C++, Java, and android ? ADT-bundle = Eclipse + Android SDK Released by Google. (I prefer to install ADT-bundle!) ? Assume install to <ADT-dir> ? Android NDK, jni native code language development kit (Some OpenCV sample is built by jni ) ? Assume install to <NDK-dir>
- 8. Import OpenCV sdk ? Extract OpenCV for Android to <OpenCV-sdk-dir> ? Run eclipse ? File?Import projects?Android? Existing Android code into workspace ? Choose the <OpenCV-sdk- dir>sdkjava
- 9. Import OpenCV4Android samples ? Extract Android-NDK to <NDK-dir> ? Run eclipse ? File->New Project? Android ?Existing Android code into workspace ? Choose <OpenCV-dir>samples<sample-name> <sample-name> = face-detection, mixprocessing, ¡
- 10. OpenCV sample build trick ? OpenCV4Android samples compile fails: ? ¡°Cannot recognize android-10 !¡± ? Open Window?SDK Manager, check the SDK version (android-17 or ¡) which is installed on local ? ,Change to local installed Android-SDK version ? ¡°Cannot find ndk-build.cmd !¡± ? Project->properties?C/C++ build? Builder Settings?Build command ${NDKROOT}ndk-build.cmd ? Set path to <NDK- dir>ndk-build.cmd
- 12. Before Upload & install OpenCV samples to Springboard ? After successully build OpenCV samples, we are going to upload *.apk to Springboard ? Setup Springboard with a Ethernet ip-address ? Springboard¡¯s Android OS?Settings?Ethernet : enable and set a static ip address for it, <Target IP>. ? Enter terminal C:> (in Win), or bash$ (in linux) ? Find <ADT-dir>sdkplatform-toolsadb.exe ? adb kill-server ? adb devices , (when debugging through USB cable) ? adb connect <Target IP> , (when debugging through ethernet)
- 13. Upload & install OpenCV samples to Springboard ? In eclipse, ¡°Run as Android application¡±, or ¡°Debug as Android application¡± ? Springboard will run the uploaded Android application
- 14. Comment for Springboard ETK Android OS ? No Internet web browser apk ? No App Store (Google Play), need to use adb install to upload *.apk ? Built-in script language, python, ruby. ? Built-in library Smart ETK, OpenCV, usb-to-serial, processing, and streaming rtsp library ? Need Start-up tutorial on Android / Linux www.viaspringboard.com
- 17. More application ! ? Since OpenCV runs smoothly on Springboard ? Robotic visual ? Security surveillance ? Other application ? NAT, media streaming ? Car mobile computing, since 12V is suitable for Car power-supply ? Public area electronic-art decoration, with Processing, light-sensor & light control ? Electronic advertisement
- 18. Springboard(Brain) OpenCV, Pattern Recognition, Communation Arduino(Spine) Collision Reflex, Interrupts, Chassis Usb-to-serial or BT 12V Battery Reflex action Afterward acknowledge Radio / WiFi
