ubuntu20.04 vins-fusion 运行记录

过程记录

环境：
ubuntu20.04
opencv4.2.0(此次使用) 3.3.1(其他程序在使用)

vins-fusion
vision_opencv

1.下载VINS-Fusion和cv_bridge，并进行修改，方便使用opencv4.2.0和对应的cv_bridge。

mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/src
# 下载 VINS-Fusion
git clone https://github.com/HKUST-Aerial-Robotics/VINS-Fusion.git
# 下载cv_bridge 1.16，不存在多个版本的opencv可以不下，直接编译VINS-Fusion
git clone https://github.com/ros-perception/vision_opencv.git --branch noetic
# 我只想保留cv_bridge，想带着vision_opencv的可以不做
mv /vision_opencv/cv_bridge ./
rm -rf vision_opencv

2.编译cv_bridge
修改cv_bridge中的CMakeLists.txt和package.xml

# CMakeLists.txt
project(cv_bridge_4)
# package.xml
cv_bridge_4

编译cv_bridge

cd ~/catkin_ws
catkin build cv_bridge_4

3.编译VINS-Fusion
修改CMakeLists.txt，这一步是因为系统中有多个opencv，所以我需要确定是哪个并使用对应版本的cv_bridge

# /home/robot/catkin_ws/src/VINS-Fusion/camera_models/CMakeLists.txt
# /home/robot/catkin_ws/src/VINS-Fusion/loop_fusion/CMakeLists.txt
# /home/robot/catkin_ws/src/VINS-Fusion/vins_estimator/CMakeLists.txt
find_package(OpenCV REQUIRED)  ⇒ find_package(OpenCV 4 REQUIRED)
cv_bridge  ⇒   cv_bridge_4

编译

ERROR 1：

error: ‘integer_sequence’ is not a member of ‘std’
FIX：
修改文件，不使用c++11而是c++14

# 修改/home/robot/catkin_ws/src/VINS-Fusion/camera_models/CMakeLists.txt
# 修改/home/robot/catkin_ws/src/VINS-Fusion/global_fusion/CMakeLists.txt
# 修改/home/robot/catkin_ws/src/VINS-Fusion/loop_fusion/CMakeLists.txt
# 修改/home/robot/catkin_ws/src/VINS-Fusion/vins_estimator/CMakeLists.txt
set(CMAKE_CXX_FLAGS "-std=c++14")

OpenCV版本和cv_bridge版本问题

FIX：
查看上方步骤，选择对应的opencv版本和cv_bridge版本，并修改CMakeLists.txt
