In step S1, the measurement system collects the minimum and maximum values of an arm from a preset fixed area during the stretching process, and uses the difference between the maximum value and the minimum value as the arm length value of the arm.

Specifically, when the user clicks the measurement button displayed on the mobile device, the measurement system acquires an arm length acquisition instruction, and displays a prompt message on the mobile device to prompt the user to move the mobile phone towards a fixed area to perform the arm stretching action, to help The user performs the corresponding arm stretching action. Wherein, the fixed area may be an ear, or an area directly facing the mobile device. Starting from acquiring the arm length collection instruction, the measurement system reserves an arm length collection period for the user to perform the arm stretching action, and acquires the distance sensor provided by the middle distance sensor of the mobile device in real time during the arm length collection period. Distance value, from which the maximum and minimum values are picked.

Preferably, the measurement system determines how the mobile device retracts the arm facing the fixed area, including: based on the acquired arm length acquisition instruction, capturing image data within a preset arm length acquisition period, and identifying the image data When the fixed area is included in the data, the distance value provided by the distance sensor from the preset fixed area is collected, and at the end of the preset arm length collection period, the maximum value is selected from the collected distance values and the minimum value; then the difference between the selected maximum value and the minimum value is used as the arm length value of the arm.

For example, the measurement system simultaneously starts the imaging device and the timer in the mobile device based on the acquired arm length acquisition instruction, the timer is timed according to the set arm length acquisition period, and the imaging device is used for the measurement The system provides image data in real time. The measurement system recognizes in real time whether the image data contains feature information corresponding to the fixed area, if so, collects the distance value provided by the distance sensor at this time, if not, continues to recognize the next image data, until the end of the arm length collection period. Next, the measurement system selects a maximum value and a minimum value from the collected distance values, and uses the difference between the selected maximum value and minimum value as the arm length value of the arm.

In step S2, the measurement system captures and recognizes the image information of the straightened arm turned to the shoulder on the other side, and collects the horizontal angle value at this time.

In step S3, the measurement system calculates the shoulder width in the right triangle formed by the arm length, the shoulder width and the horizontal angle by using the triangle side angle formula.

Here, if the collected horizontal angle is an obtuse angle, it is transformed into a supplementary angle of 180°. The arm length value is taken as the hypotenuse of a right triangle, and the horizontal angle value corresponding to the acute angle is the angle facing the right angle side where the shoulder width value is located. Then, the shoulder width value is obtained by using the preset calculation formula of right-angled side angles.
