Fail to run EuRoC example #9

Thanks for the awesome work! The code is well written with high readability!

Here is a problem for me. Though I built the project successfully, when running the example of EuRoC, I failed.

My config: Ubuntu: 17.04 OpenCV: 3 from github master (after installing ros seems like the computer starts to use ros-lunar-opencv3, as in error shows below) ROS: Lunar (but I did not use ROS)

Here is the error: czm@czm:~/SLAM/ORB-YGZ-SLAM$ ./Examples/Monocular/mono_euroc Vocabulary/ORBvoc.bin Examples/Monocular/EuRoC.yaml /home/czm/Dataset/EuRoC_MAV/mav0/cam0/data Examples/Monocular/EuRoC_TimeStamps/MH01.txt WARNING: Logging before InitGoogleLogging() is written to STDERR I0729 10:18:43.053556 3470 System.cc:107] This is YGZ-SLAM, forked from ORB-SLAM proposed by Raul Mur-Artal, University of Zaragoza.

Thanks for the help!

Hi, I fixed the OpenCV issue from using ros-lunar-opencv to the normal opencv-master from github, by modifying the CMakeLists.txt: (I installed opencv in /home/czm/opencv)

SET("OpenCV_DIR" "/home/czm/opencv") find_package(OpenCV REQUIRED PATHS "home/czm/opencv") if(NOT OpenCV_FOUND) find_package(OpenCV 2.4.3 QUIET) if(NOT OpenCV_FOUND) message(FATAL_ERROR "OpenCV > 2.4.3 not found.") endif() endif() include_directories(${OpenCV_INCLUDE_DIRS})

While the result of running the EuRoC exmaple is still a failure: Segmentation fault (core dumped) When running VINS demo of it, it shows again similar result:

imagestart:0 OpenCV Error: Assertion failed (0 <= _rowRange.start && _rowRange.start <= _rowRange.end && _rowRange.end <= m.rows) in Mat, file /home/czm/opencv/modules/core/src/matrix.cpp, line 489 terminate called after throwing an instance of 'cv::Exception' what(): /home/czm/opencv/modules/core/src/matrix.cpp:489: error: (-215) 0 <= _rowRange.start && _rowRange.start <= _rowRange.end && _rowRange.end <= m.rows in function Mat

Aborted (core dumped)

I think there might be some bug with the code. I will also update the status when finding anything.

@gaoxiang12 After a bunch of debugging, I found that the main issue might come from the value initialization in frame due to some compiler differences. My friend's computer runs the code well with Ubuntu 16. But for me, I have to add one line

N = 0;

in src/frame.cc at line 282 after frame ID definition in monocular Frame part. The N = 0 will initialize the frame with value 0 in my circumstance, or it will become a randomly large number that destroy the program. In some system, this initialization is automatically done.

Hope this could help with others if needed~

Hi！ Did you find the ROS for ygz-slam? Can you share the url? thank you！
