What is a LiDAR Scanner? What to do on iPhone, iPad?

LiDAR scanners are being featured on the latest Apple products (as of October 2020). So do you know what LiDAR scanner is and what its functions are on iPhone , iPad ? Check out this article for more information!

1. What is LiDAR Scanner?

LiDAR (Light Detection and Ranging) or LiDAR scanner is a miniature 3D scanner, which works similar to a ToF 3D sensor but performs more accurately.

Specifically, the sensor of the LiDAR scanner emits a short laser beam into the surrounding environment, based on light reflected back from the object, it calculates the distance to the object to produce a 3D map of space, the object is scanned.

2. What is the LiDAR scanner used for?

LiDAR technology was born in 1960 and had the first applications in the military and the aerospace industry. Later, LiDAR technology was used more commonly and expanded to self-driving cars or robot vacuums to help identify obstacles, interior design and especially camera technology. Specifically how to follow along!

2.1. Take photos to remove fonts, focus at night

LiDAR contributes to improving the device's imaging capabilities. According to Apple, the LiDAR scanner can measure objects as far as 5m, when combined with the camera and motion sensor data can accurately recognize details in the image, ensuring the background is blurred. the best way in portrait mode.

In addition, the LiDAR scanner is capable of autofocusing as well as subject detection very well when taking photos and videos in night mode to help improve image quality.

2.2. Enhance experience on apps, augmented reality (AR)

With LiDAR, users only take a few seconds to create a 3D map of the entire room and objects in the game are arranged around. Users can interact with virtual objects in the room instantly without scanning the environment before downloading AR applications. This allows the AR experience to be even more enjoyable.

2.3. Self-driving vehicle development

LiDAR technology plays a key role in the development of self-driving vehicles. With the ability to create 3D maps of the environment quickly, LiDAR helps self-driving cars "see" around and warn of potential dangers in traffic.

In fact, Apple tested LiDAR sensors on self-driving cars in 2015 and published a detailed description of LiDAR's 3D object recognition system on self-driving cars in 2017. As you can see, the technology This still holds great potential for future applications.

3. Which Apple devices have built-in LiDAR scanners?

The LiDAR scanner first appeared on the iPad Pro 2020 . And on October 14, 2020, the LiDAR scanner was also equipped by Apple on its newly launched products, iPhone 12 Pro and iPhone 12 Pro Max .
