Preparation

• Hardware

  • Ouster LiDAR
  • Tier4 C1 Camera with driver - tier4-camera-gmsl_1.1.1_arm64.deb
  • ADLINK RQX-58G with JetPack 4.6 - L4T R32.6.1

• ROS 1 Melodic Environment

  You can simply use ros_menu to install ROS.

• Jetson Inference

  Please follow jetson-inference to download and build the environment for Deep Learning. In this demo, we are going to use the detectnet of jetson-inference.
