本文主要是介绍intel的realsense2安装对齐，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

安装步骤：

关于pyrealsense2 2.30.0.1177

看这个

https://www.zhihu.com/question/298545345/answer/515573083

测试系统Ubuntu16.04

运行代码

uname -r

如果>=4.4.0-50的版本则ok，否则需要升级内核。

内核更新步骤：

https://blog.csdn.net/z17816876284/article/details/79159518

依赖：

sudo apt-get install git libssl-dev libusb-1.0-0-dev pkg-config libglfw3-dev
sudo apt-get install libgtk-3-dev
sudo apt-get install libglew-dev

 

apt-get安装方式：

第1步：

sudo apt-key adv --keyserver keys.gnupg.net --recv-key F6E65AC044F831AC80A06380C8B3A55A6F3EFCDE || sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-key F6E65AC044F831AC80A06380C8B3A55A6F3EFCDE

第2步：

sudo add-apt-repository "deb http://realsense-hw-public.s3.amazonaws.com/Debian/apt-repo xenial main" -u

第3步：很慢，不知道为啥

sudo apt-get install librealsense2-dkms
sudo apt-get install librealsense2-utils

测试：

打开终端输入：realsense-viewer

此时并没有安装开发包，无法编程

第4步：这一步我没尝试，太慢了。。。。。

sudo apt-get install librealsense2-dev
sudo apt-get install librealsense2-dbg

第4步我采样自己编译的方式：

https://github.com/IntelRealSense/librealsense/blob/master/doc/installation.md

下载：

https://github.com/IntelRealSense/librealsense

sudo cp config/99-realsense-libusb.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules && udevadm trigger
./scripts/setup_udev_rules.sh
./scripts/patch-realsense-ubuntu-lts.sh

查看是否成功：

lsmod | grep videobuf2_core

sudo dmesg | tail -n 50

编译：

mkdir build && cd build
cmake ../ -DBUILD_EXAMPLES=true
sudo make uninstall && make clean && make -j8 && sudo make install

一直卡在了：

Building with TM2

https://github.com/IntelRealSense/librealsense/issues/3125

https://github.com/IntelRealSense/librealsense/issues/3182

https://github.com/IntelRealSense/librealsense/issues/2737

https://github.com/IntelRealSense/librealsense/issues/2719#issuecomment-474823042

打开cmakelist.txt

显示

这里会有一点慢 

Download firmware 0;"returning early; file already exists with expected SHA1 hash" for D4XX_FW_Image-5.11.15.0.bin
Download firmware 0;"returning early; file already exists with expected SHA1 hash" for D4XX_RC_Image-5.11.15.0.bin
Download firmware 0;"returning early; file already exists with expected SHA1 hash" for SR3XX_FW_Image-3.26.1.0.bin

勾选Python选项

 

换成其他Python，带有torch环境的，后续检测+深度

https://www.cnblogs.com/z1141000271/p/10554341.html

 

勾选example

 

mkdir build && cd build
cmake ../ -DBUILD_EXAMPLES=true
sudo make uninstall && make clean && make -j8 && sudo make install

测试一下，打开install

./realsense-viewer

进行深度图对齐：
