Watermark embedding apparatus and method, and watermark detecting apparatus and method for 3D printing environment차원 프린트-스캔에 강인한 프린트 축 추정 기반 블라인드 메쉬 워터마킹 방법 및 장치
In a watermark embedding method and apparatus, a layered three-dimensional model is aligned in a printing direction based on a layering direction of the layered three-dimensional model. Then, a watermark having a predetermined pattern is embedded into the aligned three-dimensional model in a direction orthogonal to the printing direction so that the embedded watermark is not associated with the printing direction
