0、本机基础环境：

CUDA:11.4 Jetpack:5.1.2 L4T:35.4.1 Ubuntu:20.04 focal camera:zedm

因此，在官网下载安装包：ZED SDK 4.2 - Download | Stereolabs
选择对应的版本，同时SDK 版本与zed-ros2版本有对应关系，这点需要注意一下。
本文下载的是ZED_SDK_Tegra_L4T35.4_v4.1.2.zstd.run；即SDK4.1.2版本
需要注意的：根据安装的SDK版本来选择对应的zed-ros2版本。

1、ZED SDK安装

参考官方安装步骤：How to Install ZED SDK on NVIDIA® Jetson - Stereolabs
按照提示安装即可；

chmod +x ZED_SDK_Tegra_L4T35.4_v4.1.2.zstd.run
./ZED_SDK_Tegra_L4T35.4_v4.1.2.zstd.run

2、 ZED SDK卸载
步骤也很简单，主要是找到安装位置；

cd /usr/local
sudo rm -rf zed

3、zed-ros2 安装

参考官方指导：Getting Started with ROS 2 and ZED - Stereolabs
官方代码仓库地址：https://github.com/stereolabs/zed-ros2-wrapper/tree/humble-v4.1.4?tab=readme-ov-file

然后按照官方步骤就可以安装

mkdir -p ~/ros2_ws/src/ # create your workspace if it does not exist
cd ~/ros2_ws/src/ #use your current ros2 workspace folder
git clone  --recursive https://github.com/stereolabs/zed-ros2-wrapper.git
cd ..
sudo apt update
rosdep update
rosdep install --from-paths src --ignore-src -r -y # install dependencies
colcon build --symlink-install --cmake-args=-DCMAKE_BUILD_TYPE=Release --parallel-workers $(nproc) # build the workspace
echo source $(pwd)/install/local_setup.bash >> ~/.bashrc # automatically source the installation in every new bash (optional)
source ~/.bashrc

其中的rosdep update 出现错误，rosdep update一直显示超时; 网上有不同的解决办法，但是本文采用了 @鱼香ROS 的方法（感谢小鱼）

sudo pip install rosdepc  
sudo pip3 install rosdepc

安装好rosdepc后，然后运行下面代码：

sudo rosdepc init
rosdepc update

同理，在本文用到的rosdep 指令统统改为rosdepc
这样的话就可以顺利完成安装，如果安装过程中出现报错，基本是没有安装对应的包，然后从网上找一下安装步骤即可；由于安装时间有一段时间，记不清楚了哪些问题。可以参考这些github上的问题：

https://github.com/stereolabs/zed-ros2-wrapper/issues/272
https://github.com/stereolabs/zed-ros2-wrapper/issues?page=2&q=is%3Aissue+is%3Aclosed

这样的话就安装成功啦，连上相机，运行一下指令：

ros2 launch zed_wrapper zed_camera.launch.py camera_model:=zedm

这里有个小插曲，我的jetson安装了conda,base环境的python是3.9版本，导致运行不成功。我切换到另一个环境，python是3.8版本，然后就可以了。我也很奇怪，后面解决了再贴上。

python3.9运行错误：

python3.8环境：然后这样就可以啦。
