Automatic Symmetrizing Mannequin Construction from 3D Body Scanner

In this paper, the mannequin for each individual person is constructed using information obtained from 3D body scanner. The collected measurements data are standardized for SizeThailand body shape sizing. The created mannequin represents each size of Thai women body shapes. The problems are that these collected 3D data of these sizes are asymmetry and have unpleasant rough surface. In practical application, asymmetry body adjustment is solved manually but time-consuming and cumbersome. Hence, we explore the simple and automatically methods that are able to solve these problems and easily implemented. Our methods consist of 6 steps as follows: data rearrangement, symmetric plane construction, the template side selection, symmetric torso creation, torso trimming and mannequin surface smoothing. The 30 women samples data were tested by measuring chests, waists and hips of created mannequins comparing with the corresponding original 3D model. Processing time for each sample is approximately 894 milliseconds. The results show that the created mannequins have the accuracy of 98 - 99% with the SD of 0.5 - 1.1 for measurements of the chests, waists and hips. In overall, the sizes of 30 created mannequins are compared with their original 3D scanned sizes categorized based on SizeThailand size chart and the accuracy is calculated to be 90%. There are errors found in 3 of 30 mannequins as they are +/- 1 size from their original sizes.
