Point Cloud qt-creator with PCL library, Linux





  • Dear All,

    Does anyone have an experience with getting a 3D point cloud with qt-creator in combination with pcl library or opencv?

    Hi,

    Do you mean something like described here ?



  • Yes, thank you for the link.
    For now it causes some EGL error on qt creator start though.
    Are there ways to resolve the qtcreator EGL dependency?

    Where are you running Qt Creator ? On the TK1 directly or on a desktop computer ?



  • I'm running[I has been running] , I was attempting to run the qt-creator at a jetson jtk, but due to some experiments the OS got down and I will continue investigating the issue after flashing[reinstalling ] the OS.
    Thank you.
    Andrey

    In what order to you have your includes ?



  • It turned out that the project I've tried to compile sadly doesn't support embedded platforms :https://github.com/kbalisciano/rgbdslam_v2.
    It is said by its author that there are chances to run the project after "cut of" 3D from the files, though.



  • thx, qt vizualizer which is pcl_vizualizer works fine with the Jetson JTK1 after the last Tegra release installed. It hardly helps get 3d reconstruction using RGB camera though.
