The influence of optimized algorithm extracting contour on 3D digital mannequin generation

eMTM (electronic Made-to-Measure) is a kind of digital clothing technology that emerges in the 21st century. The core part of it is three-dimensional digital mannequin generation engine. The paper improves the related algorithm of original three-dimensional digital mannequin generating technology by researching mannequin generation method in three-dimensional digital clothing. Particularly, it puts forward the idea that using iterative thresholding method to extract the human body contour for solving shadow problem existing in the photos submitted by the users. Therefore, it can improve the outline continuity of human body image, strengthen the reliability about characteristic data obtained later and enhance the accuracy generating three-dimensional personalized digital mannequin.
