# 1. Introduction to Depth Camera

## 1.1 Overview

The **Aurora 930**, part of the **Deptrum® Aurora 930 Series Depth Cameras**, utilizes **3D structured light technology** to capture the three-dimensional structure of objects and environments. By fusing RGB images from the color camera with depth data, it delivers efficient and convenient **3D perception capabilities**.
