摘　　要：沂蒙小棉袄是沂蒙地区的传统民族服饰,被评为山东省非物质文化遗产。目前主要制作者为老年人,暂未建立有效的传承机制,面临手艺失传的严峻挑战,因此,借助数字化技术对其进行保存十分必要。利用多视角近景影像进行沂蒙小棉袄三维重建,生成点云数据,利用Alpha-shape算法和泊松盘重采样算法对其进行优化,生成精度高、真实感强的沂蒙小棉袄三维模型。经验证,上述方法生成的沂蒙小棉袄三维模型精度均符合要求。提出的基于沂蒙小棉袄三维重建方法具有成本低、精度高、效率高、可视化等优点。该方法可有效保存沂蒙小棉袄的纹理、图案等传统工艺元素,提高小棉袄制作的精度与质量,增加购物的真实感,为数字化定制、虚拟试穿提供数据支持。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.
