Fail to load dataset

[Engindreamer]

Hello, Dr./Mr./Ms. Yang,

I successfully build the project in Ubuntu 20.04 along with MulRan and Mulran player. However, when I initiate the node of RINO and play recorded bag file of KAIST02 dataset via rosbag play command, there is no clear process of "Map Building" or trajectory trace on Rviz, just like the figure showing below.

I think I may not correctly set up for ros node or loading the right parameters. Could you tell me which step I did wrong? Many thanks.

You may need to modify the rino.launch file,
<node name="rviz" pkg="rviz" type="rviz" args="-d /home/yangsc4063/SLAM/Radar_SLAM/RINO_release/src/rino/rviz/rino_rviz.rviz" />.
Change my global path to yours and it should be fine!

Well, I have already notice that before I run catkin command, and its effect was shown in the previous comment and didn't work.

This really confuses me. Can you try typing rqt_graph in the terminal to check if the nodes are communicating properly?

Solved this problem by downgrading OpenCV from 4.6.0 to 3.4.16....and after that your map was build very clear
