Ubuntu18.04+ROS melodic 跑通VINS-MONO的一些踩坑记录

VINS-MONO的一些踩坑记录

0 本机环境

笔者的环境为Ubuntu 18.04 + ros melodic + opencv 4.1.1 + Eigen 3.3.9 +ceres solver-1.14

• 跟VINS-MONO官方环境 ( Ubuntu 16.04, ROS Kinetic, OpenCV 3.3.1, Eigen 3.3.3, ceres solver)不同

1 踩坑开始

• 第一个报错:‘CV_GRAY2BGR’ was not declared in this scope
  这是由于opencv版本高引起的，解决方法添加头文件：

#include 

• 第二个报错：‘CV_AA’ was not declared in this scope
  解决方法添加头文件：

#include 

• 第三个报错：‘CV_CALIB_CB_ADAPTIVE_THRESH’ was not declared in this scope
  解决方法添加头文件：

#include 

• 第四个报错:‘CV_FONT_HERSHEY_SIMPLEX’ was not declared in this scope
  解决方法添加头文件：

#include 

2 坑里打滚

这个时候直接catkin_make虽然可以通过，但是运行起来会遇到怀疑人生的报错。

实际上这个问题vins-mono的issue里面也有人提到，对方的解决方法是降低CV的版本，问题有效解决。这个时候我们大胆怀疑应该是ROS自带的CV——bridge与CV版本对不上的问题。
遇到一堆不靠谱的改cv_bridge的，最终最终终于遇到了一个靠谱的，这里放上链接：

3 问题解决

然后修改完之后，就可以跑通了。
