The Design And Implemention Of Measurement System Of The Physical Parameters Based On Image

The Student time is a period during rapid growth of human body as well as a crucial stage of human growth. The issue of teenagers’healthy constitutions concerns both personal development and the future of the country. So far, however, there is something wrong with students’physical health, a gap between peers at home and abroad. To explain the problem, their physical state must be measured accurately. How to apply the means of information to fleetly and accurately to collect their physical parameters, a vital criterion to students’health, is the key before measuring it.This paper firstly expounds the problems existing in the physical health of students, according to which the author puts forward the necessity and importance of the measurement of students’ physical parameter measurement, describing the status quo and the development of three dimensional measurement technology, briefly introducing several kinds of three dimensional human body parameters measurement technology. The, by comparison and analysis the advantages and disadvantages of various methods, considering factors such as the cost, efficiency and practicability of the measurement, the author selects a method based on image processing technology to develop the system of students’ physical parameter measurement.The general process of image processing technology, including grayscale image processing,binarization processeing,edge detection and the points of physical points is also the basic image processing steps of this research to develop the system. Then after completing this system, suitable samples can be selected to collect data to be analyzed and compared. The data can be helpful for related education department to carry out quality-oriented education and to promote the all-round development of students.
