Since the odom is not accurate enough, you can use a sensor fusion (odom + IMU) or (odom + camera) or correct the odom e

The Easiest way is to teleop the TB3 without SLAM and record the topics (/odom, /tf). Then play the recorded bag file on

I 'm currently trying to compare the maps of SLAM algorithms for Alignment, Therefor The SLAM maps size must be the same to get meaningful results. If I use the following generated SLAM card for the comparison, the comparison would not be reliable. I have tried to create maps of the gazebo Environment with the following SLAM Algorithms (gmapping, hector, karto and cartographer) on TB3 waffle. I got very different map size of the generated SLAM maps. Although resolution value is 0.05 for all SLAM algorithms. here the size of SLAM maps:

SLAM        |Gmapping SLAM | Hector SLAM | karto SLAM | Cartographer
----------- | ------------ | ------------| -------- | ---------------
Width      | 384           | 2048        | 71       | 61
Height     | 384           | 2048        | 82       | 99

Gmapping map: |
Hector SLAM map: Karto SLAM map |
Cartocrapher SLAM

how can I get the same Maps size of all SLAM algorithms. for example like this

I have used a Image editor such as ImageMagik to resize the maps, but it has bad impact on the shape of the Environment.

I have used the following gazebo environment for each SALM.

roslaunch turtlebot3_gazebo navibot.launch

       -  roslaunch turtlebot3_slam turtlebot3_slam slam_methods:=gmapping
       - roslaunch turtlebot3_slam turtlebot3_slam slam_methods:=hector
       - roslaunch turtlebot3_slam turtlebot3_slam slam_methods:=karto
       - roslaunch turtlebot3_slam turtlebot3_slam slam_methods:=cartographer

I hope you can help me :)
