bag_to_pcd invalid characters

Hello

I transformed a rosbag file to pcd file by rostool bagto_pcd.

with some success output like this:

Got 50384 data points in frame velodyne on topic /velodynepoints with the following fields: x y z intensity ring time Data saved to rostooloutput/1628410321.879456997.pcd

Got 50367 data points in frame velodyne on topic /velodynepoints with the following fields: x y z intensity ring time Data saved to rostooloutput/1628410321.979679108.pcd

Got 50357 data points in frame velodyne on topic /velodynepoints with the following fields: x y z intensity ring time Data saved to rostooloutput/1628410322.079864025.pcd

But when I clicked the pcd file. the header part is valid, with some info like FIELDS SIZE HEIGHT DATA binary but the following data parts are invalid characters

Thanks in advance

The header suggests by using DATA binary that your editor is trying to show binary values instead of UTF-8 etc.

Can you use some visualization tool, like https://foxglove.dev/, to visualize and debug these PCDs?

Thanks. I didn't try this tool but eventually manually saved the info in ASCII format. I will try this tool next time

So what is the status of this question? Can you load this bag in the code? Was the rosbag correct? Conversion to ASCII - how did you do it manually?
