Your iPhone Pro Has LiDAR: 7 Cool Things You Can Do With It

Published

Tim Brookes

Some high-end iPhone and iPad models have a LiDAR scanner integrated into the camera module on the back of the device. This effectively gives your device 3D scanning abilities with a few unique and interesting applications.

RELATED: What Is LiDAR, and How Will It Work on the iPhone?

What Does the LiDAR Scanner Do?

LiDAR stands for Light Detection And Ranging, but it may also be commonly referred to as “3D laser scanning” or some variation thereon. The technology works by bouncing light waves at surfaces and measuring the reaction time to determine the shape and distance of objects in the area.

Think of it like RADAR (RAdio Detection And Ranging) but for light waves. Unlike RADAR imaging, LiDAR can provide more detailed and crisper scans with smaller equipment. LiDAR uses signals that work in the nanometer range, whereas RADAR requires the use of antennas that produce radio waves at much lower frequencies.

Coupled with the software on your iPhone, the LiDAR scanner can be used to create 3D representations of objects and their surroundings. To do this you’ll need the appropriate software which you can download from the App Store. Some core iPhone features, like the Camera app, will use LiDAR in other ways.

At present, only the iPhone 12 Pro, iPhone 13 Pro, iPad Pro 11-inch (2nd and 3rd generation), and iPad Pro 12.9-inch (4th and 5th generation) are equipped with LiDAR scanners. If you look at the camera array on your device, the LiDAR scanner looks like a small round black circle.

Create 3D Scans of Places You Love

Imagine if you had an interactive 3D model of your childhood home or a treehouse you built when you were young. Most of us keep photographs to remind us of places we once lived and loved, but what if instead of flat images we were able to take 3D scans instead?

Well if you have an iPhone or an iPad with a LiDAR scanner on the back, you can do exactly that. Having a 3D space to navigate is a lot more immersive than simply looking at a 2D image. Photographs and videos still have their place, but why not augment your memory bank with something you can experience in three dimensions instead?

This is possible with apps like Polycam, RoomScan LiDAR, and Canvas: Pocket 3D Room Scanner. Most of these apps are free to use, though there are paid upgrades that remove certain restrictions and improve the quality of the scans that you make. You can see LiDAR scanning in action in a YouTube video published by Polycam.

Buying a House? Redecorating? Scan First

Capturing a 3D model of a room or building has some very practical uses. If you’re currently looking to rent or buy a house, taking a scan of the building can help you make up your mind whether or not the place is for you. The process is very similar to taking a walk-through video or series of photographs, both of which are common practices in the real estate world.

Not only is a 3D scan more immersive, but it’s also easier to compare sizes, layout, practical space, and potential for renovation and other major work. We’d recommend taking detailed photos and videos in addition to your scan, which works best with apps like Polycam and RoomScan LiDAR.

If you’re planning major work in a home you already own, a 3D scan can give you a base from which to work in a 3D modeling app like Blender (if you’re comfortable working in such an app). Alternatively, it can provide a nice “before and after” comparison to look back on.

And lastly, selling your house without a real estate agent is surging in popularity. These apps allow you to provide 3D environment scans to potential buyers while still cutting down on expensive agent fees.

Create Your Own 3D Assets

Photogrammetry is the act of creating 3D objects from photographic data, and it’s a time-consuming process. While the assets that photogrammetry provides are often highly accurate and detailed, the process of taking an item from a series of photographs to a finished model you can use can take hundreds of hours.

By comparison, a scan made on an iPhone or iPad with an app like Polycam can take a matter of minutes. Scanning an object is a bit like taking a video, and when you’re finished you can export a file that can be used in 3D modeling apps like Blender. Once you’ve tidied up your scan you can import objects into 3D engines like Unity and Unreal.

These engines are used heavily in game development, film, and interactive media. Conor O’Kane is a game developer with a YouTube channel who has not only used this technique but created a tutorial showing how to do this and why small developers might be interested in the process.

Scan and Share Interesting or Cherished Items

Are you a collector? Whatever it is you collect—art, plants, games consoles, or even cars—you might get a kick out of exhibiting it online, in a 3D format. Polycam is perfect for this since it includes built-in model sharing with the rest of the Polycam community, or “polyworld” as the app refers to it.

Some people share ice cream or rock crystals, others share their extensive sneaker collection. Even if you don’t have a LiDAR scanner on your iPhone or iPad, Polycam may still be worth the download just to see what people are scanning and sharing.

It’s like Instagram but for 3D models with an interactive element that other forms of media don’t come close to. It’s easy too, even if you make a bit of a mess while scanning the app has intuitive crop controls that allow you to remove background or surface objects.

Tip: For best results, place your item on a stand, pedestal, or stool before scanning

Take Better Photos in the Dark

Your iPhone and iPad already do this, so you don’t need to activate anything to get the benefit. However, if you’re putting off taking photos in the dark since you don’t trust your device’s autofocus, you might want to reconsider if you have a LiDAR-equipped device.

Since LiDAR is capable of judging distances based on how long it takes the light waves to return to the sensor, autofocus in the dark can be better calculated.

While standard cameras and non-LiDAR equipped models use contrast and phase detection autofocus (what Apple calls “Focus Pixels”) which struggle in low light, your LiDAR-equipped model fares much better. Coupled with Night mode you should be better equipped to take photos in the dark.

Measure More Accurately

You may not have realized this but Apple includes an app called Measure with iOS by default. If you’ve previously discounted and deleted it you can download Measure again for free from the App Store.

The app uses augmented reality to measure real-world distances simply by pointing your phone at a surface. Tap the plus “+” icon to start the measurement and move your device to see it in action.

iPhone Measure app

With a LiDAR scanner, augmented reality is vastly improved on the iPhone and iPad. Measure has gone from being a fun party trick to surprisingly accurate. In our tests, the app was right most of the time, with a margin of error of around 1 cm. This may depend more on how shaky your hands are than anything.

Get More From AR Apps

Measure is just one such AR app that performs better when paired with a LiDAR-equipped iPhone or iPad. Every other AR app can benefit from the sensor, which provides a more stable experience by gauging distance using light rays rather than estimations derived from a “flat” image.

LiDAR really helps to improve the AR experience across the board, like when you’re creating art in apps like World Brush, SketchAR, and Assemblr. Need to provide remote assistance for a real-world problem? Vuforia Chalk allows you to scribble on real-world objects to help relay the point.

Try out various bits of IKEA furniture in your house with IKEA Place, or bring your child’s LEGO sets to life with LEGO Hidden Side, as demonstrated in the above YouTube video published by the Brothers Brick. If you’d rather have a more educational AR experience, Playground AR provides a whole physics sandbox to play around with.

Of course, these experiences are available on just about any recent iPhone, but the experience is considerably more stable with a LiDAR scanner. Find even more apps to enjoy in Review Geek’s roundup of the best AR apps for iPhone and Android.

Apple’s Mixed Reality Headset Inches Closer to Release

Published

on

Apple

While rumors of Apple’s AR and VR “mixed reality” headset have been floating around for years, it sounds like things are starting to heat up. Last week, Apple reportedly showed its board of directors the next-gen headset, signaling a release could be near.

According to a report from Bloomberg, not only did members of the board get to see and try the new Apple VR headset, but engineers are working hard to develop rOS (Reality OS,) the operating system for the wearable.

The report mentions that seven members of the board, along with CEO Tim Cook, got up close and personal with the new VR headset. However, we’re not sure if it was a complete working prototype or the condition of the unreleased device.

And while there are no mentions or even suggestions that the release date is inching closer, it makes sense given that board members are getting a glance at it. Furthermore, lending credence to the idea, Bloomberg said there’s some precedence here, as the board often sees new devices ahead of announcements.

Does that mean Apple is gearing up to release (or at least start teasing) its upcoming mixed reality headset? We’re not sure. If so, we could see some sort of small teaser at the upcoming Apple WWDC developer conference.

That said, earlier reports from Bloomberg suggested that Apple had to push back its plans and release schedule due to “challenges related to content and overheating,” not to mention some issues with the camera system.

Either way, it certainly looks like Apple’s VR headset ambitions are not only heating up but that the project is inching closer to a release date. Considering Bloomberg said nearly 2,000 employees are working on it, maybe we’ll see it sooner than later.

How to Add Google Drive to File Explorer

Published

on

Adding Google Drive to File Explorer lets you access your cloud files without having to open a web browser. You can then manage your cloud files act as if they’re your local files. Here’s how to set that up on your Windows PC.

To add Google Drive to Windows File Explorer, you’ll use the free Google Drive app. This app integrates your cloud files with your local PC, allowing you to upload new files, download existing ones, and enable and disable file syncing.

RELATED: How to Download Files and Folders From Google Drive

Link Google Drive to Windows File Explorer

To start the integration, first, launch a web browser on your PC and open the Google Drive download page. There, click “Download Drive for Desktop” to download the app to your computer.

Select "Download Drive for Desktop."

When your file is downloaded, double-click it to run the installer. In the “User Account Control” prompt that opens, choose “Yes.”

You’re now on Drive’s installation wizard. Here, on the “Install Google Drive?” page, choose if you’d like to add Drive and Google’s online office suite shortcuts to your desktop.

Then click “Install.”

Select the shortcuts option and choose "Install."

When the app is installed, you’ll see a “Sign in to Google Drive” window. Here, click “Sign in With Browser.”

Select "Sign in With Browser."

Your PC’s default web browser will open taking you to the Google site. Here, Google will ask if you’d like to allow your newly installed app to access your Drive files. Enable this permission by clicking “Sign In.”

Choose "Sign In."

Google will display a message saying you’ve successfully signed in to your Google account in the Drive app. Close the browser window as you don’t need it anymore.

Successfully signed in to the Google Drive app.

And that’s it. Google Drive has now been added to your File Explorer. Access it by opening the File Explorer utility using the Windows+E keyboard shortcut.

In File Explorer’s left sidebar, you’ll see a new item called “Google Drive.” Click it to access your cloud files in your familiar file manager app.

Configure Google Drive’s Sync Settings

To help you bring your Drive files to your PC, Google Drive offers two sync methods, each offering unique features.

The first method is called “Stream” which lets you manually download files from the cloud to your PC. If you don’t want to fill up your PC’s storage with all your Drive files, this is the method you should enable.

The other method is called “Mirror” which keeps your Drive files on both your cloud storage and your PC. Since this downloads a copy of all your cloud files to your PC, your PC’s storage will fill up pretty quickly.

Once you’ve decided on the sync method you want to use, configure it in the Google Drive app. Do this by first clicking the Google Drive app icon in your PC’s system tray (the bar located at the bottom of your screen).

You’ll see a Drive pane. Here, in the top-right corner, click “Settings” (a cog icon) and choose “Preferences.”

Choose Settings > Preferences.

On the window that opens, in the left sidebar, click “Google Drive.”

Select "Google Drive" on the left.

On the right pane, enable either “Stream Files” or “Mirror Files,” depending on what method you’ve decided to use.

Choose "Stream Files" or "Mirror Files" on the right.

And Google Drive will sync your cloud files accordingly. Enjoy!
