This range-finder(telemeter) measures the distance to a target by the camera perspective. The effective distance is 10m-1km. To measure the distance, you should know the height(width) of a target.
Don't worry!! Man's height is 1.7m(5.6ft), a golf flag is 7ft, a bus is 3.2m(10.5ft), a door is 2.1m(7ft). With that, we can guess the height(width) of almost everything.
If you know the airplane model, you can measure the height from the sky. For reference, Boeing 747's width is 72 meters.
Usage is simple. Input the height of the target, and touch the screen. If the target is aligned by 2 lines, get the measured distance.
* Now, 3 tools for distance were completed.
1) Smart Ruler (Short, touch) : 1-50cm
2) Smart Measure (Medium, trigonometry) : 1-50m
3) Smart Distance (Long, perspective) : 10m-1km
Speed Gun's Usage is also easy. It can measure the speed of a moving object by touch (speedometer, velocimeter).
To measure the speed, input the closest distance to the target, and touch the screen following target. If yours is inaccurate, you can calibrate with the [Speed Calibration].
For more information, see the manual, Youtube video and the blog. Thank you.
* Smart Tools package does NOT include what is in this app.
