3D technology is already part of our everyday life — from smartphone face recognition and AR applications to autonomous vehicles and industrial inspection.
In this episode of 3D Scan 101, we explore two key technologies that help transform the physical world into digital 3D data: structured light and LiDAR.
Starting from the 3D technologies inside smartphones, we’ll look at how structured light creates detailed 3D maps, how professional 3D scanners use the same principle to capture object geometry, and how LiDAR helps devices measure depth and understand their surroundings.
You’ll learn:
🔹 How infrared structured light enables 3D face recognition
🔹 How structured light 3D scanners reconstruct shapes and surface details
🔹 How smartphone LiDAR works and enables AR and 3D capture
🔹 How LiDAR is used in autonomous vehicles, robotics, and mapping systems
🔹 The key differences between structured light and LiDAR
Whether you’re interested in 3D scanning, reverse engineering, digital modeling, industrial inspection, or emerging 3D technologies, this episode will help you understand how devices capture and digitize the world around us.
