Abstract
This paper proposes a new oil painting digitization method using photogrammetry technology to compensate for the deficiencies of the existing methods. The color and the 3D geometric information of the oil painting are recovered better by acquiring several sets of orthophotomaps, and modeling accuracy is ensured with a control mesh or by flattening. The 3D reconstruction and digital representation of oil paintings mainly includes two aspects: 3D geometric information recovery of oil painting surface and color rendition of oil painting. Photogrammetry can acquire a digital 3D model of the surface geometrics of an oil painting, restore the color image and plane geometry of the painting in the form of orthophotomap, and implement the 3D digital representation of color in the painting.
