Question

Hi all,

I am running the map_merger and adhoc_communication nodes.

Upon running Rviz in Ubuntu 14.04.02 in ROS Indigo, the map that I am receiving is not being displayed in Rviz's Map Panel.

I am getting the following error in terminal when it crashes.

:~$ rosrun rviz rviz

I briefly saw this today and fixed by making sure the image topic I want was coming through (I was subscribing to topics published on another host, and ROS network wasn't properly configured). Very partial info but still HTH.

I got into the same issue and realized it was actually image encoding issue. In my case, I tried to encode gray scale image into "bgr8" for image publisher. Obviously, this is invalid. Maybe you had the same issue?

I can second this, turns out my image should have been encoded as mono8 instead of bgr8 and I changed the following line to rectify the situation:

sensor_msgs::ImagePtr msg = cv_bridge::CvImage(std_msgs::Header(), "mono8", total_area_flip).toImageMsg();
