ROS Wrapper: Process Died Issue with ORB_SLAM3 Using OpenCV 3.2.0

[setareh-soltanieh]

Hi everyone,

I have successfully run ORB_SLAM3 on my computer and tested it with the EuRoC dataset and a Realsense T265 camera, and everything works fine. However, I am facing a "Process has died" issue when trying to use the ROS wrapper.

Details:
OpenCV Version: 3.2.0 (I have deleted all other OpenCV libraries)
ROS Wrapper: Built without any errors
For debugging, I am attempting to run the EuRoC dataset with ROS. I know my code doesn't go beyond this line in ORB_SLAM3/System.cc:
cv::FileStorage fsSettings(strSettingsFile.c_str(), cv::FileStorage::READ);
I have ensured that the path in strSettingsFile.c_str() is correctly assigned.

Steps Taken:
Verified the OpenCV version and removed other versions.
Confirmed that the settings file path is correct.
Built the ROS package without any errors.
Issue:
The process dies at the aforementioned line, and I am unable to determine the cause.

Can someone please help me identify and resolve this issue?

Thanks in advance!

Hi a bit late to answer but I got a similar open CV error and was able to fix it by fixing some typos in my yaml file.
