UniversalRuler is designed to precisely determine the size of any object. It is easy to use and allows you to measure objects as easily and accurately as a traditional ruler or tape measure.
Due to the limitations of ARKit, the device needs to exceed 6s, and the minimum system requirement is iOS11
Make sure you have enough light
How to use:
First, make sure the objects you want to measure are in the same camera image.
Second, make sure you want to measure objects parallel to the camera (this is to avoid image distortion caused by the camera view).
Finally, align your cameras middle icon to the left or right of the object you want to measure. When the icon turns green, click the button and move slowly to the destination you want to measure. The navigation bar in the application displays the size of the measurement object and then clicks the button to complete the measurement.
If there is no alignment or parallel move may lead to distortion of the correct size, you can click the button at the bottom right to measure, if the right operation method can accurately using the traditional ruler or measuring tape.
