A non-contact measuring method in pediatrics is disclosed. An infant model is established by acquiring a human image and a depth image of a subject infant updating the infant model by acquiring a plurality of anthropometric characteristic points and finally obtaining an anthropometric data of the subject infant from the updated infant model. This invention also provides an apparatus to achieve the above mentioned measuring method. An infant model which includes anthropometric characteristic points and 3D surface models is established based on a human image acquired by an image acquisition module and a depth image acquired by a depth information acquisition module in conjunction with an algorithm program built in a data acquisition and processing module. Human anthropometric data is obtained by analyzing the infant model. The non-contact measuring method and measuring apparatus in pediatrics make the measuring process more humane without contacting a subject body.
