You could have heard about Apple together with a lidar sensor within the iPhone 12 Professional and the iPhone 12 Professional Max, two of the firm’s newest iPhone fashions. The brand new sensor improves portrait photographs, and even night time mode pictures captured with the iPhone 12 Professional’s rear digital camera as a result of it hastens focus and portrait mode photographs. However that is not all lidar may also help with. 

Lidar stands for “gentle detection and ranging” and it really works by bouncing lasers off of objects to measure their distance, based mostly on how lengthy it takes for the sunshine to get again to the sensor. The sensor itself is not new tech — in actual fact, the 2020 iPad Professional ($950 at Amazon) has lidar, too — and the identical tech is usually utilized in self-driving vehicles

This is one occasion trick I simply found, with the assistance of MacRumors, and I lay out a number of extra beneath.

For my first trick, this is easy methods to use the iPhone 12 Professional’s digital camera to measure an individual’s peak in simply a few seconds (I did this with my children they usually cherished it).


Fairly cool stuff, proper? 


1. Open the Measure app in your iPhone. 

2. Level the rear digital camera at an individual who’s both standing or sitting and be sure to get their total physique — from head to toe — within the body. 

3. After a second or two, a line will seem above their head with an estimate of their peak, together with objects like their hair or a hat. 

4. You’ll be able to take an image of the measurement with a faucet on the shutter button, saving it to your digital camera roll. 

In my testing, the measurement was correct inside half an inch. My son’s curly hair triggered his first measurement to be half an inch too excessive, however after he combed it down, it was spot on at Four ft, 7.5 inches. 

I additionally examined it on myself, and small issues just like the angle of my head or carrying a hat resulted in the identical barely brief 5 foot, 9 inch studying. Once I stood straight up, nevertheless, wanting straight on the digital camera and not using a hat on, it was extra correct, with a 5 foot, 10 inch studying. 

You will get a tough estimate of greater than only a individual’s peak with the Measure app. You should use it to get the size of a bit of furnishings, for instance, to see if it would match by means of a door. I lately measured a TV to settle a debate on whether or not it was 55 or 65 inches (it was 65). 

When the Measure app first launched with iOS 12, I defined easy methods to use it to measure random family objects or determine sq. footage. With the addition of lidar on Apple gadgets, the app is getting extra correct. So in the event you’ve upgraded your iPhone, it is price giving the Measure instrument one other shot.

The lidar sensor is not restricted to simply measuring completely different objects. You should use it to create 3D maps of a room (as proven above), or a 3D recreation of a single object, which you’ll be able to then print out on a 3D printer once you use an app like Polycam

In response to CNET’s Scott Stein, the Apple Arcade recreation Scorching Lava makes use of the lidar sensor to scan a room, after which he might conceal digital stuff behind actual objects within the room, like a chair. 

As extra apps are up to date to enhance the augmented actuality expertise because of the lidar sensor, there isn’t any telling what else we’ll be capable of do with appropriate iPhone and iPad fashions. 

After impressing your family and friends together with your iPhone 12’s ($799 at Apple) enjoyable trick, make sure that to try these hidden options in iOS 14.
