Smart Distance is a range-finder using camera perspective. There are 20,000+ Android devices in the world, with different camera lenses and performance. So it is not easy to measure the target's distance with camera view. I calibrated the app on 700+ major devices for 3 years.
※ Introduction video
※ How to use
1) To measure the distance from a target, enter its height (width).2) Adjust the target to green lines by touching screen.
By the way, do you know target's approximate height (width)?
※ Target's height or width???
For accurate measurement, it is important to know the height (width) of a target exactly.
Don't worry. We can guess the height (width) of objects around us.
- Height
man : 1.7m (5.6ft), golf flag : 2.1m (7ft), door : 2.0m (6.5-7.0ft)
We also can find target's specifications. For example, The Statue of Liberty = 93m (305ft), The Boeing 777 = 74m (243ft)
※ Golf-rangefinder ???
This app can be a good tool for golf players because you know the height of golf flags.
※ How to calibrate it
Is the distance inaccurate? You can calibrate it with [Height(Width) Calibration] at the settings. When height calibration is 36, it means that your camera view has 36 degrees range vertically.
