Error when I run fast_mapping_node

[ghowoght]

When I run roslaunch fast_mapping fast_mapping.launch, it reported
/home/robot/ahri2.1/ahri2.1_rc2/ros_ws/lib/fast_mapping/fast_mapping_node: error while loading shared libraries: libopencv_core3.so.3.3: cannot open shared object file: No such file or directory, but I have already install opencv3.3.0.
Could you tell me how to resolve it?

I resolved it. Because libopencv_core3.so.3.3 is located in /opt/ros/kinetic/lib/x86_64-linux-gnu/, but I run it in ubuntu18.04 and ros melodic, it can't find the file. This library must run with ubuntu 16.04 and ros kinetic.
