Height measuring device and method

Abstract

The invention provides a height measuring device which comprises a platform and a liftable measuring support arranged on the platform. A weight sensor connected with a control unit is further arranged on the platform and used for sensing the weight borne on the platform and transmitting signals to the control unit so as to estimate the height of a person to be measured; a camera, a display screen and a human face recognition module are arranged on the measuring support; the camera is connected with the human face recognition module and the control unit in sequence, and used for capturing human face information so as to achieve height measurement correction and feedback. The invention further provides a height measuring method, and coordinates of a face feature portion are obtained through human face recognition so as to control the measuring support to ascend and descend for measuring the height; the height measuring device has the advantages that during measurement, the height just needs to reach the actual height of a human body and does not need to exceed the human height, body contact during measurement is avoided, the device can be started from any height, the measuring time is shortened and the measuring efficiency is improved.

Description

technical field [0001] The invention relates to the field of human body height measurement, in particular to a height measurement device and a measurement method. Background technique [0002] Traditional height measuring instruments require a measuring device higher than the height of the human body. When measuring, the ruler end of the measuring device needs to be abutted against the top of the person to be measured to achieve height measurement; after the measurement is completed, the ruler end of the measuring device It is easy for the person to be measured to leave the measurement position; it can be seen that for the person to be measured, the traditional height measurement device needs a certain amount of physical contact to achieve the measurement, and for the convenience of the next measurement, the traditional height measurement The scale end of the device is usually raised to a size larger than the height of the general human body, the measurement efficiency is lo...

[0002] Traditional height measuring instruments require a measuring device higher than the height of the human body. When measuring, the ruler end of the measuring device needs to be abutted against the top of the person to be measured to achieve height measurement; after the measurement is completed, the ruler end of the measuring device It is easy for the person to be measured to leave the measurement position; it can be seen that for the person to be measured, the traditional height measurement device needs a certain amount of physical contact to achieve the measurement, and for the convenience of the next measurement, the traditional height measurement The scale end of the device is usually raised to a size larger than the height of the general human body, the measurement efficiency is low, and the space is relatively occupied; in addition, when a large number of people to be measured need to be measured in a hospital or a nursing home It takes a lot of time to fill in relevant indicators and parameters, the efficiency is too low, and it cannot be converted into electronic files in a timely manner. Therefore, it is necessary to design a method that can complete height measurement without physical contact and store the measurement information electronically. or transmission device
