【安装】Ubuntu上下 Intel Real Sence D455 的安装

Ubuntu上下 Intel Real Sence D455 的安装

1. Download SDK

1. 下载源码，第一步先将librealsense的github下载下来：

$ git clone https://github.com/IntelRealSense/librealsense.git

单独下载比git快，可能需要翻墙，否则很慢

2. 安装依赖环境

$ sudo apt-get install libusb-1.0-0-dev libglfw3-dev libgtk-3-dev
$ sudo apt-get install libudev-dev      (不装make时会报错找不到libudev.h)

libusb是一个USB设备访问接口库；
gtk是一个图形工具包；
glfw是一个OpenGL应用框架；

2. Installing the packages （SDK Platform）

在下载下来的librealsense-master中的readme.md中有安装教程：

• Register the server’s public key:
  sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key F6E65AC044F831AC80A06380C8B3A55A6F3EFCDE || sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-key F6E65AC044F831AC80A06380C8B3A55A6F3EFCDE In case the public key still cannot be retrieved, check and specify proxy settings: export http_proxy="http://<proxy>:<port>"
  , and rerun the command. See additional methods in the following link.

• Add the server to the list of repositories:
  sudo add-apt-repository "deb https://librealsense.intel.com/Debian/apt-repo $(lsb_release -cs) main" -u

• Install the libraries (see section below if upgrading packages):
  sudo apt-get install librealsense2-dkms
sudo apt-get install librealsense2-utils
  The above two lines will deploy librealsense2 udev rules, build and activate kernel modules, runtime library and executable demos and tools.

• Optionally install the developer and debug packages:
  sudo apt-get install librealsense2-dev
sudo apt-get install librealsense2-dbg

  With dev package installed, you can compile an application with librealsense using g++ -std=c++11 filename.cpp -lrealsense2 or an IDE of your choice.

Reconnect the Intel RealSense depth camera and run: realsense-viewer to verify the installation.
使用內附的Type-C線接上電腦，Viewer會自動抓到並且詢問是否安裝


都安裝完之後就可以開始操作了

Verify that the kernel is updated : modinfo uvcvideo | grep "version:" should include realsense string

补充：RealSense Viewer

先将所有的模块都打开来看，分别是深度模块 (Stereo Module)、RGB摄影机 (RGB Camera)、动作感测模块 (Motion Module)，右上角有3D、 2D两种模式可以选择，这边我转换成2D的模式，最后可以看到总共有4个画面出来，左上是深度摄影机的信息、左下是RGB、右上右下分别是陀螺仪及加速度计。
