Missing assignments to copy_cloudKeyPoses6D, copy_cloudKeyPoses2D, and copy_cloudKeyPoses3D lead to errors at runtime.

In the previous code is:

        mtx.lock();
        *copy_cloudKeyPoses3D = *cloudKeyPoses3D;
        copy_cloudKeyPoses2D->clear();            // giseop
        *copy_cloudKeyPoses2D = *cloudKeyPoses3D; // giseop
        *copy_cloudKeyPoses6D = *cloudKeyPoses6D;
        mtx.unlock();
