In this video, I have explained a step by step method of scanning 3D space using the LIDAR sensor of the iPhone 12 Pro phone using Polycam app.

At the time of recording this video, the LIDAR sensor is available in iPhone 12 Pro, iPhone 12 Pro Max and iPad pro.

You can try the app yourself here https://apps.apple.com/us/app/polycam-lidar-3d-scanner/id1532482376
