The Yimeng small cotton padded coat, recognized as a traditional attire of the Yimeng area and designated as an Intangible Cultural Heritage by Shandong Province, currently faces an urgent challenge of craft preservation due to the advancing age of its principal artisans and the absence of a structured inheritance system. This study employs digital technology to address this issue, utilizing multi-view close-range images for the reconstruction of the Yimeng coat. The research applies the Alpha-shape algorithm and Poisson disk resampling algorithm to refine point cloud data, yielding a highly accurate and realistic 3D model. Validation confirms that the generated 3D models satisfy the necessary accuracy standards. The proposed 3D reconstruction method offers a cost-effective, accurate, efficient, and visual approach that successfully retains the traditional craft elements such as textures and patterns of the Yimeng coat. Consequently, this method enhances production quality and authenticity in retail, while also providing data that supports digital customization and virtual fitting.
