不知道啥时候自己能买得起这个相机，拍照留个纪念。
NVIDIA Jetson installation (intelrealsense.com)
固件跟新地址Firmware Update Tool (rs-fw-update) (intelrealsense.com)
安装IntelRealsense D435i驱动，注意该过程中不能接入摄像头：
git clone https://github.com/jetsonhacks/installRealSenseSDK.git
cd installRealSenseSDK
./buildLibrealsense.sh 这里可以选择安装版本，默认为V2.5.0
### 一些可以参考的链接：https://github.com/IntelRealSense/librealsense/blob/master/doc/distribution_linux.md等待一个小时左右脚本才会运行结束，连接摄像头，先运行realsense-viewer查看摄像头能否正常使用。然后可以python3 然后import pyrealsense as rs查看是否安装正确。如果出现nomodule的报错则需要找到~/librealsense/build/wrappers/python该路径下的六个gnu文件，复制到 /usr/local/lib/python3.6中，我得设备python版本3.6,注意自己得环境
then find the pyrealsense2 in ~/librealsense/build/wrappers/python copy the six file use following command sudo mv ~/pyrealsense2/ /usr/local/lib/python3.6nvidia@nvidia-desktop:~/librealsense/build/wrappers/python$ ls CMakeFiles pybackend2.cpython-36m-aarch64-linux-gnu.so pyrealsense2Config.cmake pyrealsense2.cpython-36m-aarch64-linux-gnu.so.2.50 cmake_install.cmake pybackend2.cpython-36m-aarch64-linux-gnu.so.2 pyrealsense2ConfigVersion.cmake pyrealsense2.cpython-36m-aarch64-linux-gnu.so.2.50.0 Makefile pybackend2.cpython-36m-aarch64-linux-gnu.so.2.50.0 pyrealsense2.cpython-36m-aarch64-linux-gnu.so我安装完sdk好像就自己生成这个目录了，但是还是拷贝了一下.so文件，该步骤结束后再编辑bashrc修改环境变量
export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3.6/pyrealsense2
添加这一行至bashrc中再source ~/.bashrc即可再import pyrealsense as rs查看是否安装正确
1、建立workspace，已经有的可以跳过可以参考安装ros教程先安装(9条消息) Jetson系列 安装ros自动化安装_无证驾驶梁嗖嗖的博客-CSDN博客_jetson 安装ros
mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/src/
catkin_init_workspace
cd ..
catkin_make
echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc
source ~/.bashrc
2、在catkin_ws/src/下载源程序
cd src
git clone https://github.com/intel-ros/realsense.git
cd ..
catkin_make

刚开始找得解决办法如下，这个可能是老版本得记录：
sudo vi /opt/ros/melodic/share/cv_bridge/cmake/cv_bridgeConfig.cmake真实解决办法如下：
将94和96行得opencv改成opencv4即可

cv2.imshow('depth', depth_colormap)
print(f'Depth: {depth} m')
if cv2.waitKey(1) == ord("q"):

finally:

到这里只是能打开无法获取imu，接着干

如果就一个摄像头可以不加序列号 ,fuab3.0和固件改了还是没启动imu,再看看别的原因毕竟第一次用使用手册什么得也没用到，应该还是相机配置问题。

主要记录一下在jetson xavier上编译的时候由于opencv版本问题导致的错误以及解决方法：
主要流程见参考链接。其中会遇到三个错误：
1、在code_utils下面找到sumpixel_test.cpp，修改#include "backward.hpp"为
#include “code_utils/backward.hpp”2、在code_utils中的sumpixel_test.cpp和mat_io_test.cpp 中添加如下两行：
#define CV_LOAD_IMAGE_UNCHANGED -1
#define CV_LOAD_IMAGE_GRAYSCALE 0
#define CV_LOAD_IMAGE_UNCHANGED -1 #define CV_LOAD_IMAGE_GRAYSCALE 03、在code_utils中的sumpixel_test.cpp中，将CV_MINMAX换成
NORM_MINMAX以上是我遇到的问题和解决方法。
注意code是否编译成功
