Fusion not happening on my data #10

Open adhilcodes opened 1 year ago

adhilcodes commented 1 year ago

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?

Hi, sorry for the delay of this message. Your problem could be because the image and point cloud topics do not have a proper header. Make sure the topics have a timestamp.

This is my rosbag. Is there any issue with header or timestamp?

Hi @adhilcodes, have you managed to get it running on your own data? Could you show an example data output of lidar and camera with "rostopic echo" ?

Hi, if you still have problems with your data, you can use the rosbag. I just uploaded to test the algorithm.
