2019-05-20 01:13:19 -0500 | marked best answer | ar_track_alvar publication rate too small Hello! These days I'm trying to use ar_track_alvar to track ar tags but the publication of ar_track_poses is too slow. I use Ubuntu 16.04 and ros kinetic. My CPU is Intel I7 with 8G memory. When I use ar_track_alvar, it onlypublish /ar_pose_markers at poorly 0.2hz. I also found that the problem is the rate at which the callback function is called. That function is called merely once every 5 secs. But I can't find anything wrong. I also checked the Here is the code and the I have also tested it on Ubuntu 14.04 and ros indigo, the publication rate is 1hz. However my friend can use it with a publication rate of 8 hz on Ubuntu 14.04 and indigo. That's very odd. Thanks! |
