System and method for 3D measurement and monitoring of human head circumference growth

Abstract

The invention provides a system and a method for 3D measurement and monitoring of human head circumference growth. The system comprises a data acquisition module for acquiring RGBD image data collected by a plurality of depth camera devices surrounding the human head of a measured person at 360 degrees; a data splicing module for splicing the RGBD image data acquired by the data acquisition module; a model reconstruction module for reconstructing a 360-degree model of a human head with color and depth; a mark identification module for determining mark points for image testing of the head circumference; a head circumference calculation module for calculating the head circumference length; and a file monitoring module for storing the determined head circumference length into the personal file of the measured person and evaluating whether the current head circumference length and the change of head circumference length are normal according to the head circumference file of the measured person. The system can collect accurate data of human body at all angles without stimulation, identify and calculate image characteristics after re-modeling and determine the head circumference length and the change of head circumference length, and is beneficial to medical research.

Description

technical field [0001] The invention relates to the fields of 3D scanning technology and image processing, in particular to a system and method for 3D measuring and monitoring the growth of human head circumference. Background technique [0002] Children are fundamentally different from adults in that they are in a constant process of neonatal development, with body size, proportions, body composition, and organ function changing and maturing with age. Abnormalities at any point in the growth process can affect part or the entire body, and the damage is sometimes temporary and reversible, and sometimes permanent. Therefore, regular measurement and monitoring of the development of the head circumference of infants and young children can detect abnormalities in which the head circumference is too large or too small in time. If it is not normal, you should find out the shortcomings of its nutrition, environment and lifestyle and correct it; or check for hidden diseases (such a...

Problems solved by technology

[0003] However, there are different defects in various measuring devices related to human body data at present: 1. Measurement technologies such as laser scanning require the measured object to remain inactive for a certain period of time, which is especially not suitable for measuring children, and is not conducive to improving the accuracy of manual measurement; 2. In order to improve the clarity of the measurement image, some combined cameras use flashlights to assist shooting, which is not conducive to the emotional stability of the people being measured, especially children, and is not user-friendly; 3. Manual measurement requires staff to manually find and determine the position of the head circumference , children's cooperation is generally poor, and there are human measurement errors; 4. The anthropometric device mainly stays at the stage of acquiring image data, does not include the recognition and calculation of image content, and cannot directly provide interpretable data describing medical characteristics
