3.Nuwa-HP60C Camera Introduction (Depth Camera Only)

📷 Angstrong Nuwa-HP60C 3D Depth Camera Introduction and Usage

1. Course Overview

This course will introduce the basic characteristics of the Angstrong Nuwa-HP60C 3D Structured Light Depth Camera equipped on the A1 Pro robot, and demonstrate how to use ROS 2 driver to start the camera node, use rqt_image_view and RViz2 to view RGB color stream, Depth stream, IR infrared images, and 3D spatial dense point cloud in real-time.

🎯 Course Objectives

  1. Understand the structured light measurement principle and core hardware parameters of the Angstrong Nuwa-HP60C depth camera

  2. Master how to use ascamera to start the depth camera driver node

  3. Master how to subscribe and visualize RGB color image, 16-bit depth map, and 3D point cloud in ROS 2 environment

Important

This course is only applicable to users with the Angstrong Nuwa-HP60C Depth Camera version.

2. Camera Hardware Introduction

image-20260110113735688

The Angstrong Nuwa-HP60C is an industrial-grade micro 3D structured light depth camera, consisting of VCSEL laser speckle projector, infrared receiver, and high-resolution RGB sensor:

  • Measurement Range: 0.2m ~ 4m

  • RGB: 1280×720 / 640×480 @ 30FPS

  • Depth: 640×480 @ 30FPS, 16-bit millimeter-level accuracy

  • Field of View: H73.8° × V51.7°

  • Interface: Type-C USB 2.0 / 3.0

3. Preparation and Driver Startup

3.1 Start Camera Driver Individually

Open the terminal and run the following command to start the camera low-level driver:

xxxxxxxxxx
ros2 launch ascamera hp60c.launch.py

image-20260903120741784

3.2 Start Camera Driver and RViz Visualization Integrated Environment

If you need to start the driver and automatically pop up RViz2 point cloud monitoring and topic monitoring:

xxxxxxxxxx
ros2 launch dofbot_pro_bringup nuwa_camera_view.launch.py

image-20260903144228054

  • Subscribe to depth image, select /ascamera_hp60c/camera_publisher/depth0/image_raw depth image topic
