Currently I can successfully generate the map output file but I have no idea how to display it in practice. Basically, it should be a 2D SLAM map.
The project I'm using is available at the following link on Github. This project basically uses Google Cartographer 2D SLAM without ROS.
Compiling the project I get an output file called "map_output" but it seems to be completely raw: it's not even binary. How can I convert or read it in a viewable format?
Inside the main file, specifically inside the main function, it can be seen how data consisting of inertial measurements (IMU) is taken as input and processed to provide an output map.
