The built-in distance measurement function of Apple mobile phones provides users with a convenient and fast measurement method.
1. Sensors and Algorithms
The ranging function of Apple phones relies on a variety of sensors, including accelerometers, gyroscopes and magnetometers. These sensors measure changes in the phone's acceleration, direction, and magnetic field, respectively. By processing this data with advanced algorithms, Apple phones are able to calculate relatively accurate distances.
2. Usage tutorial
- Open the rangefinder: Pull down the search interface, enter "rangefinder" and enter the application.
- Select the starting position: a circle and a point will appear on the screen, move this point to the starting point to be measured.
- Start measuring: Click the plus icon (+) at the bottom of the screen to mark the starting position, then move the camera until you see the end point you want to measure. Click the plus icon (+) again to complete the measurement.
- Record results: The measurement results will be displayed on the screen. You can also click the photo button to save the measurement results.
3. Accuracy factors
- Distance limit: In order to ensure the accuracy of the measurement results, it is recommended to keep the distance between the iPhone and the object being measured between 0.5 meters (2 feet) and 3 meters (10 feet).
- Light conditions: Use the ranging function in a well-lit environment to avoid too dark or too bright environments affecting measurement accuracy.
- Angle problem: Try to keep the iPhone perpendicular to the object being measured to avoid measurement errors caused by squinting or tilting.
- Object surface: The surface of the object to be measured should be flat and without obvious bends or unevenness to ensure that the laser line can accurately contact the object surface.
4. Precautions
- Although the distance measurement function of Apple mobile phones is relatively accurate, there is still a certain error compared with professional measurement tools.
- Environmental factors (such as indoor signal reflection, user holding style, etc.) and user factors (such as irregular movement pace, mobile phone vibration, etc.) may affect the measurement results.
Through the above tutorials and instructions, we hope to help you make better use of the ranging function of your Apple phone and improve the efficiency of your life and work.
