tracking_lib cannot run well and the rviz cannot display the obj's trajectory

[ryontang]

thanks for your sharing of this perception project, after build the whole project, i run the demo of segment_lib, it can run well and display the box and heading angle of obj in the rviz.

But, when it comes to node of tracking_lib, it fails to work properly:

1. when run the file of demo.launch of tracking_lib, it output some errors with red font
   

2. and the rviz interface output:
   

3. when i use the rqt_graph of ROS print out the relation of topic in nodes, it shows:
   

i don't know where is the problem, very appreciate for your help!

have you rerun again？And if failed again，hope to capture the full log of tracking_node.

i just run the launch file of kitti_ros and tracking_lib;

After running a while and capture its log and then use Ctrl+c to stop, the log is:

... I will run the demo this week. And maybe I can remote assist if fine.

refers to the subcriber between nodes, it seems have no problem, how do you debug your project use ide?

[Durant35]

no ide... maybe due to pcl...you build it release？
catkin build -DCMAKE_BUILD_TYPE=Release

catkin build -DCMAKE_BUILD_TYPE=Release

ok, i have a try, thanks a lot!

Sorry to bother you !

Actually, the PCL is 1.9 in my pc, and i have tried to build a new workspace and git clone the src file, according to the steps in README.md of project tracking libs(also use catkin build -DCMAKE_BUILD_TYPE=Release):

I roslaunch the kitti_play.launch and the demo.launch of tracking_lib, it still report the same errors, as i display the picture of log record above.

but strangely, then i roslaunch the kitti_play.launch and the demo.launch of segment_lib, it run normally.

catkin build -DCMAKE_BUILD_TYPE=Releasefind_package(PCL REQUIRED

Thanking for your remote assist last time, and helping me find the problem that is the references of PCL, I just uninstalled PCL 1.9, and changed find_package(PCL 1.8 REQUIRED) to find_package(PCL REQUIRED).

At last, the whole project runs well!
