Measurement Methods Research of Body Surface Angle Based on MATLAB

In order to make clothing, furniture, cars and other products design more in line with ergonomic principles, analysis of convex and concave surface features of the human body and its measurement methods is necessary. Body surface is constituted by a number of curved surfaces and convex and concave characteristic of these surfaces can be quantified with angle value. Convex and concave characteristic of front, side and back body can obtain angle expression by quantifying. In the paper, automatic extraction of body surface angle can be obtained by using MATLAB, error analysis of extracted data is done and the results show that the method is feasible which provides basis for the development of relevant body features measurement machines and relevant industries´ product design.
