本文是在Orin nx上已经安装并用zed2相机跑通Vins-Fusion感知建图的基础上进行Vins-Fusion-gpu进行修改的内容，一些基本的库文件，依赖安装，只讲解opecv4.6.0带GPU加速配置和cv_bridge配置以及zed2相机的配置，其他就不再这里赘述，详情请看我的其他文章：

安装opencv4.6.0带GPU加速配置和cv_bridge安装：

参考文章：

Jetson Orin NX 开发指南（5）: 安装 OpenCV 4.6.0 并配置 CUDA 以支持 GPU 加速_jetson xavier nx 配置 opencv cuda加速-CSDN博客

按上面文章是可以进行opencv4.6.0的安装的，但是cv_bridge虽然安装了但是配置上还会有一些问题，首先需要删除4.2.0版本的ROS自带的opencv：

sudo apt purge libopencv*4.2* python3-opencv libopencv-dev

然后NX中就只剩下刚刚安装的cv_bridge牵连的是opencv4.6.0。

编译Vins-Fusion-GPU：

mkdir -p ~/vins_gpu_ws/src/vins-fusion-gpu/src/
cd ~/vins_gpu_ws/src/vins-fusion-gpu/src/git clone https://github.com/pjrambo/VINS-Fusion-gpu.git

下载完成进入VINS-Fusion-gpu，修改 vins_estimator/CMakeLists.txt 文件和修改 loop_fusion/CMakeLists.txt 文件。

在vins_estimator/CMakeLists.txt 的20行和loop_fusion/CMakeLists.txt 的19行，将opencv的位置进行替换：

# include(/home/dji/opencv/build/OpenCVConfig.cmake)
include("~/Documents/opencv-4.6.0/build/OpenCVConfig.cmake")

在vins_estimator/CMakeLists.txt 的8行和loop_fusion/CMakeLists.txt 的8行，加入cv_bridge的路径：

set(cv_bridge_DIR "/home/nvidia/cv_bridge_pkg/devel/share/cv_bridge/cmake")

然后输入以下内容：

sed -i 's/CV_FONT_HERSHEY_SIMPLEX/cv::FONT_HERSHEY_SIMPLEX/g' `grep CV_FONT_HERSHEY_SIMPLEX -rl ./`
sed -i 's/CV_LOAD_IMAGE_GRAYSCALE/cv::IMREAD_GRAYSCALE/g' `grep CV_LOAD_IMAGE_GRAYSCALE -rl ./`

原因参考博客：

Jetson Orin NX 开发指南（6）: VINS-Fusion-gpu 的编译和运行-CSDN博客

编译通过之后运行数据集：

# 新开终端
cd ~/vins_gpu_ws/src/vins-fusion-gpu && source devel/setup.bash && roslaunch vins vins_rviz.launch# 新开终端
cd ~/vins_gpu_ws/src/vins-fusion-gpu && source devel/setup.bash && rosrun vins vins_node src/VINS-Fusion-gpu/config/euroc/euroc_stereo_imu_config.yaml# 新开终端
cd ~/vins_gpu_ws/src/vins-fusion-gpu && source devel/setup.bash && rosrun loop_fusion loop_fusion_node src/VINS-Fusion-gpu/euroc/euroc_stereo_imu_config.yaml# 新开终端跑数据集
cd ~/data_set && rosbag play MH_01_easy.bag

编译之后运行实际ZED2：

参考内容我的以下文章自己新建zed的相机yaml文件：

无人机避障——感知篇（在Ubuntu20.04的Orin nx上基于ZED2实现Vins Fusion）-CSDN博客

但是需要修改 zed2_stereo_config.yaml文件：

修改如下：

[注意]：其中这两个量是控制是否运行gpu的，我一开始全部置为1，发现zed2实际测试太卡了，后面就这么设置。

use_gpu_acc_flow: 0
