3D Human Body Scanning and Personalized Version Generation Model in Garment CAD System

With the increasing demand for clothing comfort and personalization among consumers, traditional clothing design methods based on standard sizes are no longer able to meet market demands. This study focuses on the application of 3D human scanning technology in computer-aided design (CAD) systems for clothing, as well as the development of personalized shirt pattern generation models based on this technology. By using high-precision 3D human body scanning equipment to obtain human body data, combined with advanced image processing and data analysis techniques, precise extraction of human body feature points has been achieved. By utilizing this feature point information, a three-dimensional clothing basic model is constructed, and the model deformation technology is used to adapt to different body types. Finally, personalized two-dimensional shirt patterns are generated based on the particle spring model. This study not only improves the accuracy and efficiency of clothing design but also provides consumers with a highly customized wearing experience, providing new ideas and methods for the intelligent development of the clothing industry.
