In daily life, we need to measure the length of an object. First of all, we think of tape measure, but we are not technicians, and no one will always carry the ruler with us. What should we do at this time?
Many friends may not notice it. In fact, there is a measurement function in the mobile phone, which can temporarily replace the ruler, and the measurement results are also very accurate.
Next, use Huawei mobile as a demonstration. Let me tell you how to use this measurement function, and it can not only measure length, but also detect a person's heart rate and breathing rate. It is really practical!
First find the "AR measurement" software on the desktop of your mobile phone. It is a tool that comes with your mobile phone. (If you don't find it, you can search and download it in the application market) After
is opened, we first download its interface. There are three icons in the middle of the right, representing the measurement of straight lines, planes and volumes. There are two options at the bottom of
, namely object measurement and anthropometric measurement. Among them, there are measurement methods such as heart rate and breathing rate in anthropometric measurement.
For example, we first choose linear measurement, and then I found a ruler to test its accuracy?
First, before measuring, keep a certain distance between the mobile phone and the object to be measured, and move horizontally and left and right along the direction of the ruler, so that the mobile phone and the ruler can maintain a horizontal line. At this time, a circle will appear on the screen.
aims the small point in the middle of the circle at one end of the ruler, and then pans the phone to the other end. I measured 10 cm, and the phone shows exactly 10 cm, which is still very accurate.
(In actual measurement, it is recommended to measure it a few more times, after all, electronic measurement is inevitable errors)
The same operation is, when we choose the second plane on the right, here I choose the mobile phone as the measuring object, and first keep the same horizontal plane as the measuring object, and then pan the mobile phone until the circle appears. At this time, a square border will appear, so that the border and the four sides of the mobile phone overlap. Click the plus sign at the bottom to measure the length and width of the mobile phone screen.
Next is the heart rate measurement. First, select the manipulation measurement at the bottom. At this time, a circular recognition area will appear on the screen. Aim at your face and hold it for a few seconds to measure the heart rate and breathing rate.
or above is the AR measurement of Huawei mobile phones. There are some operating instructions for this gadget. You can try it with your phone.
