iPhone's Secret LiDAR Superpower
Unleash 3D modeling and augmented reality with the tiny sensor on iPhone Pro models
The LiDAR sensor, a small dark circle near the rear cameras on certain iPhone Pro models, is used to measure the distance and shape of objects. This sensor, which stands for 'light detection and ranging', sends out invisible pulses of light and measures how long they take to return after hitting nearby surfaces.
The LiDAR scanner is used for features including Night mode portraits and faster autofocus in low light on supported Pro models. It is exclusive to Pro and Pro Max iPhone models, and is not available on non-Pro iPhones. Apple introduced the LiDAR Scanner with the iPhone 12 Pro and iPhone 12 Pro Max in 2020.
In addition to camera enhancements, the LiDAR sensor can be used by compatible apps and iOS features for augmented reality and other purposes. Apple's RoomPlan framework combines camera and LiDAR readings to identify walls, windows, doors, furniture, and other room features while creating a 3D model of an interior space.
The LiDAR sensor can also help create a rough 3D mesh of the physical environment using ARKit, Apple's augmented reality framework. This helps compatible augmented reality apps understand the position of floors, walls, and other surfaces.
## What is LiDAR used for? The LiDAR sensor is used to provide depth information to iOS features and compatible apps. This information can be used for measuring objects, understanding the shape of a room, or detecting nearby objects.
## Which devices have LiDAR? Every iPad Pro since the fourth-gen lineup in March 2020 has featured a LiDAR sensor. The LiDAR sensor is not limited to iPhones, but is also available on certain iPad models.
The LiDAR sensor may seem like a small feature, but it has the potential to enhance the overall iPhone experience. With its ability to provide depth information and create 3D models, it can be used in a variety of applications, from augmented reality to camera enhancements.
## Why it matters The LiDAR sensor is an important feature for iPhone users who want to take advantage of augmented reality apps and camera enhancements. With its ability to provide depth information and create 3D models, it can enhance the overall iPhone experience. As more apps and features are developed to take advantage of the LiDAR sensor, its importance is likely to grow.
