LiDAR-camera fusion not publishing fused data on my data

I have tried to fuse lidar and camera data. I have tried with two data (as rosbags). One rosbag is downloaded from the internet. Another one is I have recorded with my lidar(rs-lidar 16) and camera(zed cam - data from left eye only).

The data I have downloaded from the internet works pretty well. But while working on the data I have recorded it is not publishing any data(The published topic is blank). Why is this happening is there anything to take care of while recording my own data?

This is the repo I have tried: https://github.com/EPVelasco/lidar-camera-fusion/

Hi!

The link you posted is the repo from which you got the bag you are able to play, right? So no problem with it, correct?

As for the bag you recorded, what is the output of rosbag info <path_to_the_bag>?

This the info my recorded rosbag(LiDAR: rs-lidar 16 , Camera: Zed cam(using only one eye))
