Non-contact pediatric measuring method and measuring device

Abstract

The invention provides a non-contact pediatric measuring method. The method includes the steps: building an infant body model by acquiring body images and depth images of an infant to be measured; updating the built infant body model by extracting a plurality of anthropometry characteristic points; finally, acquiring anthropometry data of the infant to be measured from the updated infant body model. Besides, the invention further provides a non-contact pediatric measuring device implementing the measuring method. The infant body model comprising the anthropometry characteristic points and a three-dimensional surface model is built by the aid of the body images acquired by an image acquisition module and the depth images acquired by a depth information acquisition module according to algorithm programs built in a data acquisition and processing unit, and the anthropometry data are acquired by analyzing the infant body model. According to the non-contact pediatric measuring method and the measuring device, the body of the infant to be measured does not need to be contacted in the measuring process, and the measuring process is more humanized.

Description

technical field [0001] The invention relates to a pediatric measurement method, in particular to a non-contact pediatric measurement method, and also relates to a non-contact pediatric measurement device. Background technique [0002] Length / height, weight, head circumference, chest circumference, sitting height and some other anthropometric data are important growth indicators stipulated in the child growth standards issued by the World Health Organization. monitor. Since children's growth status and physical indicators such as body length and weight are closely related to children's health, the above-mentioned anthropometric data are important indicators that need to be monitored during the growth of infants and young children. [0003] Since the beginning of the 20th century, pediatric measurements have been carried out using contact measurement methods, which have never changed, and improvements to pediatric measurement equipment have also focused on contact measurement...

AI Technical Summary

Problems solved by technology

For example, infants need to straighten their limbs during the measurement process, or a ruler needs to touch the infant’s limbs, but the lack of cooperation of infants makes the measurement process very difficult and may affect the accuracy of the measurement results

[0004] Although some simple non-contact measuring devices have appeared in recent years, these devices are mainly designed for adults and are not suitable for infants and young children, especially for infants who cannot stand

And because infants and young children cannot effectively cooperate, it also makes the measurement process time-consuming and laborious, increasing the difficulty of measurement
