源码阶段

创建代码目录

mkdir -p ~/liujl && cd ~/liujl
git clone https://github.com/IntelRealSense/librealsense.git --depth=1

配置usb摄像头

cd librealsense
sudo cp config/99-realsense-libusb.rules /etc/udev/rules.d/
sudo su
udevadm control --reload-rules && udevadm trigger
exit

或者：

cd librealsense
sudo ./scripts/setup_udev_rules.sh

开始编译
