How to feed the Sample data to the system?

[zjnyly]

Sorry for asking this simple question. I'm new to this area and after I followed the instructions to run all the nodes, I don't know where to feed the Sample data to the odometry and visualize it.

I used the command

rosbag play raw-perch-loop-2021-09-06-17-22-06.bag

And it begin running

---

Then the terminal running

roslaunch llol llol.launch

displays

---

The terminal running

 roslaunch ouster_decoder decoder.launch

displays

---

The terminal running

roslaunch ouster_decoder driver.launch

displays

---

And the terminal running rviz displays

---

But there is no image shown on rviz.

Can you help me with that? Thanks!

Looks like rviz is not loading llol.rviz correctly. Try opening it manually with file->open in rviz.
