AM5728: Build extra_modules into openCV

Part Number: AM5728


Hello,

I am trying to test opencv's dnn module, but it does not look like any of opencv3.1.0's extra modules were built into the TI SDK. Is there a way for me to re-build TI's opencv to include the extra modules like dnn? I've tried building opencv using cmake, and am just getting errors regarding Qt:

CMake Error at modules/highgui/CMakeLists.txt:50 (QT5_ADD_RESOURCES):
Unknown CMake command "QT5_ADD_RESOURCES".

Any assistance is appreciated and thank you in advance.

T

    Hi T, are you trying to download and build this modules on the EVM's target system? or in your Ubuntu?.. I assume is the first but please let me know what is what you are trying to do and where.

    thank you,

    Paula

    Hi Paula, yes, build the modules into the EVM's target system. I'm further than the error above and used cmake to build the updated version of openCV into the EVM alongside ti-opencv, but when I use qmake to build the application to run on the EVM it is unable to find the newly built openCV libraries. It finds the ti-opencv libraries just fine however, and I can use

    pkg-config --modversion opencv

    on the EVM to see that opencv4 is installed and the extra modules are there.

    Thank you,

    T

    Hi T, I typically use YOCTO recipes for installing packages.. I know, no the easiest way, but let me share how I do it. My 2-cents, it in case it can help you:

    You probably would only need to modify and build opencv bitbake recepie (meta-arago/meta-arago-extras/recipes-support/opencv/opencv_3.1.bb)

    • MACHINE=am57xx-evm bitbake opencv
    • New build opencv packages could be found tisdk/build/arago-tmp-external-arm-toolchain/deploy/ipk.
    • Copy those IPK packages in target (maybe in a /home/tmp folder)
    • And install them: opkg install [package_ipk].ipk

    Hope this helps,

    Paula
