This app is great for measuring how far something or someone is from the camera. Just point the camera and tap the image on the screen. It will place a red dot where you tapped confirming that is the object to measure. It will then calculate the distance from the camera to the red dot.
Not sure if the chairs are spaced 1.5meters away, or is that person in the lift with you too close? Very handy for social distancing. Just tap on the person and it will measure the distance to the person. If the person is within 1.5 meters the bar will turn red indicating they are too close for social distancing. If they are further than 1.5 meters the bar will turn green.
Can be used to measure the distance of any object, not just people.
Please note that it measures from the camera and not from you. So if you have the camera outstretched in front of you, it will be a different measurement to you.
When you open this app it will ask you for permission to access your camera. This app can only work and only measure if it has access to your camera.
Sometimes you may need to turn the camera away and then back for it to reset and co-ordinate its location again.
Works best in good lighting.
