Actually, I didn't quite understand you. This point cloud topic is reused in two cpps for sure, and you can change it to whatever topic you like, for my case, I just changed it to
subLaserCloud = nh.subscribe<sensor_msgs::PointCloud2>("/lidar0/points_raw", 1, &ImageProjection::cloudHandler, this);
This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.
why not output the error "multiple definition of `pointCloudTopic'", because pointCloudTopic is used in two cpps.
