织物悬垂三维形态的测量与重建

介绍了用结构光测量织物悬垂三维形态的方法。利用平行结构光在织物表面形成明暗相间的等高线条纹,用基于极坐标径向扫描的方法对织物投影图像中等高线条纹及织物边缘进行识别,得到织物曲面上的等高线及织物边缘点坐标,最后利用基于极坐标网格的三维曲面建模方法对悬垂织物的三维形态进行了重建。实验结果表明,上述方法能够比较理想地实现织物悬垂三维形态的测量与重建。

Measurement and reconstruction of 3D draping shape of woven fabric

A method to measure the 3D draping shape of woven fabrics by structure light is proposed. A series of black and white stripe occurred on the surface of the fabric by parallel structure light. The contour lines and edge of the fabric in projection image are detected based on polar coordinated radial scan algorithm, by which a series of points on the contour lines and edge of the fabric are obtained. Finally, three-dimensional draping shape of fabrics is reconstructed through 3D surface modeling technique based on the polar grids. Experiment results show that the proposed method can reconstruct ideally the 3D draping shape of fabrics.
