Augmented reality enabled smart phones can help us measure width, length of objects without a tape measure or ruler. In an earlier article, we demonstrated how you can measure length and distance using a virtual ruler app on iPhone. If you have upgraded to iOS 12 however, you have the native tape measure app which is just named‘Measure’. In this quick guide, we will show you how it can help us gauge the size of objects in the real world using augmented reality (AR) technology.
First of all, make sure that you’re in a place with good lighting as the tape measure app uses your iPhone’s back camera to measure objects around you. The more light you have, the better results you’ll likely have.
Launch the Measure app from the home screen. It will ask you to move your phone around the object you like to measure. Point your iPhone camera to the object or surface. You’ll see a white dot in the middle of your phone screen. Move it to the start point and tap the + measure button to select it as the start point. Move your iPhone to the end point and tap the + measure button again to set it as the send point. The final measurement will be displayed in the middle of the line.
You can repeat the steps as many times as you like to get more accurate measurement. Tap the Undo or Clear button at the top to start over. While the measurement is displayed on your phone screen, you can tap the number to see it in inches and centimeters.
Tap the shutter icon at the lower right corner to take a screenshot with the object and its measurement on it. You can find the captured screenshot in the Photos app on your iPhone.
Measure a rectangle or square using iPhone
When you are measuring a square or rectangle, it may automatically detect the dimensions of rectangular or square objects. When you see it automatically places a measurement box around the object accurately, simply tap the + measure icon and the measurements for the object’s width and length will appear. Now move the iPhone slightly to get the object’s calculated area.
