Dear @Jiankai-Sun,

Hello, I have used your code for ORB_SLAM2. Jiankai-Sun, thanks for your code. When I have compiled your code, I have faced error:

I have used Ubuntu 14.04, ROS indigo and OpenCV 2.4.13. I also have tested your code with Ubuntu 16.04, ROS Kinetic and OpenCV 2.4.13.

I think that there is a problem in ros_mono.cc or system.cc file. Is it correct? I do not know where is the problem, exactly. I have tried a lot. your answer is very important to me. I need to save map and the load data.

Please guide me. Thanks.

Hi, same problem happens on me. (Ubuntu 16.04 + ROS Kinect) Has anybody solved this issue ?
