hello, I solve it. Just add orb_slam_->SaveTrajectoryKITTI("your_path.txt"); in destructors.

For example, you could add it to RGBDNode.cc, then it looks like:

` RGBDNode::~RGBDNode () {

orbslam->SaveTrajectoryKITTI("/home/your_name/SaveTrajectoryKITTI.txt");

delete rgbsubscriber; delete depthsubscriber; delete sync_; } `
