Abstract

A measuring approach for figure size from 3D human point cloud is presented. Using a light-stripe 3D laser scanning system to scan the desired pose of body

human’s three-dimensional coordinates are obtained without loss. Based on the directions of eyesight and the natural separating of two legs

the human’s orientation is adjusted to facing

positive direction. Applying manual method and maximal connectivity domain method to delete noisy points

6 figure points and 20 figure planes are labeled on human silhouette. Two different section planes’ y coordinates are used to obtain one length size of human and a method

called convex hull method

to measure body section’s girth

respectively. Using this technique

the 34 key figure lengths and girth sizes can be measured

and the factors affecting measurement precision can be analyzed. Measurement results show that the typical measurement error of this method is lower than 3% and can meet the requirement of industry.
