How To Use Lidar On The Iphone And Ipad – Lidar, a technology first used by meteorologists and aerospace engineers and later adopted in self-driving vehicles, has slowly entered consumer electronics over the past five years. If you have a Pro model iPhone or iPad, there’s a good chance it has a lidar sensor, and you’re likely using it whether you know it or not.
It began incorporating lidar (light detection and ranging) into its products starting in 2020 with the 11-inch iPad Pro (2nd generation), 12.9-inch iPad Pro (4th generation), iPhone 12 Pro, and iPhone 12 Pro Max. Since then, lidar sensors have appeared in all iPhone iPad Pro and Pro models. If you have a 2020 or newer Pro model, it has a lidar sensor built into the rear camera system.

Lidar works by shining a laser at something and then detecting the time it takes for the light to return to its receiver. Since the speed of light is incredibly fast, even very small differences in travel time allow your device’s software to build a three-dimensional point cloud map of an area. This 3D map can be used to measure items, create 3D representations of physical objects, and enable other cool features like placing virtual objects in your room or navigating in augmented reality (AR).
Lidar Sensor: The Promising Technology For Mobile 3d Acquisition
When it comes to AR, apps can better understand the geometry of the environment around you to place digital objects more precisely in the real world, ensuring that they adhere to the physical properties of the space. Lidar sensors provide a more realistic experience than AR on other iPhone and iPad models because they can more accurately map the surroundings captured by your camera and provide better motion tracking and depth perception.
Introduced its first API for the lidar scanner in ARKit for iOS and iPadOS 13.4, giving third-party developers access to polygonal models of the surroundings in meshes, which they could then manipulate with RealityKit to create augmented experiences. The company gave developers even more power starting with iOS and iPadOS 15.4, when it added lidar APIs in AVFoundation to provide precise, high-quality information for recording videos and taking photos.
Below, we’ll explore some of the built-in uses of lidar on your iPhone or iPad and how third-party apps expand the technology into more advanced use cases.
With a lidar sensor, autofocus capabilities in the Camera app are more advanced than some devices without lidar. Your camera’s ISP (image signal processor) uses lidar to determine how far away objects and people are so it can automatically focus on them more accurately – even in low light conditions – while reducing capture time. That’s because it measures depth data and doesn’t process the image itself.

This faster autofocus works not only for still images but also for videos, allowing you to focus on the moment and not on focusing the image in the camera. However, it should be noted that lidar autofocusing does not play friendly with windows, glass, water, and other transparent objects as it sees them opaquely.
Lidar autofocus priority is also baked into AVFoundation, a framework for accessing and capturing still images and videos from the camera so that third-party apps can also take advantage of lidar. With it, photography apps can take advantage of faster, more accurate autofocusing. And apps like Focus Puller can even bring lidar auto focusing functionality to other hardware, like BlackMagic cameras.
When Portrait Mode was first released in 2016, it used machine learning to determine the subject of the photo and properly apply the background blur. That’s still very much the case on regular iPhone and iPad models. But on Pro-level models, lidar dramatically improves the look of Portrait photos taken with the rear camera as it can help capture more accurate depth data with the image.
Even third-party apps can capture better portraits, like ProTake, which leverages lidar to let you record portrait videos with real-time blurred backgrounds. There is also a DSLR Camera, which allows you to create AR portraits using the lidar.

Lidar also makes Night mode portraits possible on iPhone 12 Pro and newer Pro models. So, when shooting portraits in a dark environment on an iPhone 12 Pro, 13 Pro, 14 Pro, or 15 Pro model, the lidar scanning function, which fires more often and often to get a better depth reading on the scene, enables Camera to quickly adapt to subject depths and change exposure settings more accurately. This can result in clear portraits captured in low light environments. On iPhone models without lidar, Night mode will not start.
While you can change the focus in Portrait photos captured on any iPhone or iPad running iOS or iPadOS 17 or later, you get better results on Pro models, which use the data captured from the lidar scanner. On iPhone 15 Pro models, you can even refocus regular photos as long as you have Portraits in Photo Mode enabled.
The Measure app, which uses AR technology to map your environment and measure objects within the frame, essentially turns your iPhone or iPad into a digital tape measure. Although it is available on any iPhone or iPad model since iOS 12, it is easier and more accurate to use Pro models with lidar scanners because it better understands the spatial relationship between you and the objects in the frame.
With lidar, measurements are much more accurate than on devices that rely solely on camera data and motion sensor processing. Lidar also provides a ‘Measuring app with vertical and horizontal edge guides. Measure will automatically detect edges once you point the circle close to them, snapping the yellow guides along the sides so it’s easier for you to see and follow them. On models without lidar you will only see a dotted, non-sticky line after you mark your first point.

Lidar also provides more granular measurements with Ruler View, which allows you to measure items more precisely in increments. Simply plot a line and then move closer to it to show the ruler.
Lidar-equipped Pro models also benefit from having a measurement history in the Measurement app (tap the List button). It is not the responsibility of the lidar itself, but it is responsible for giving you additional measurement details. When you’re measuring something, tap the measurement and expand the window to see information like the elevation, distance from you, angle, and more. For example, when viewing an area, you will see an example of the shape and additional units of measurement.
There are also plenty of third-party measurement apps that use lidar, such as Measure LiDAR, which will give you the distance between you and any object. It will even let you set a specific distance between you and a fixed point, giving you an approximation of when you will reach the distance. Laser Rangefinder – LiDAR also uses lidar to provide “measurements with millisecond-level accuracy” for ranging.
One of the coolest features of the Mesur app is the ability to calculate the height of a person sitting or standing. This functionality is limited to iPhones and iPads equipped with lidar. Whenever the Measure app detects a person sitting or standing in the frame, it automatically includes their measurement at the top of their head, hair or hat. Take a picture using the shutter button to share the image with the measurement.
Here Is The Super Cool 6 Things You Can Do With Iphone’s Lidar
Accessibility tools are important to , and its never-ending promise to make technology accessible to everyone led to the Magnifier app, first introduced in iOS 10, which helps users zoom in and identify items in the camera frame easily. With iOS 16 and iPadOS 16, Pro models added Door Detection, which uses lidar to map and identify doors and their distance away.
Text descriptions of the door appear on the screen, such as the distance away, whether it is open or closed, what type of door it is, how it swings, if there are any signs on it, and more. VoiceOver can also provide descriptions for blind and visually impaired users.
Other apps are available to assist users who are blind or have low vision, such as Microsoft’s Seeing AI, which uses lidar and augmented reality to help a user explore their surroundings, along with audible announcements of objects using spatial audio. In a simpler implementation, there is LiDAR Sense. With this app, you hold your iPhone in front of you, facing your rear camera where you are walking, and the app will vibrate harder and make a louder sound as you become closer and closer to objects in your path.
While your iPhone or iPad already has many built-in uses for lidar, it also has its own Clips app for you, which can scan and transform the space you’re recording video in with AR effects. With a video open in the app, tap the star icon to open the effects menu, then tap the AR Spaces icon. Start the scan, start the effect, and select the AR Space you want to use in the scene.
