“…Thus, 3D reconstruction has become a promising technique for the digitization of rock-art. An early example in the rock-art domain is presented by Landon & Seales [11] who propose a system for 3D acquisition and presentation of Puerto Rican petroglyphs. A more recent approach that considers multiple scales to acquire 3D data of petroglyphs together with their surrounding rock panel has been proposed by Alexander et al [2].…”

Petroglyphs (rock engravings) are important artifacts for the documentation and analysis of early human life. Recent improvements in 3D scanning and 3D reconstruction enable the accurate 3D reconstruction of petroglyphs from rock surfaces at sub-millimeter resolution. To enable the indexing, matching, and recognition of petroglyphs in petroglyph databases, the shapes must first be segmented from the reconstructed rock surface. The absence of robust 3D segmentation methods for petroglyphs leaves a gap in the digital processing workflow. In this paper, we present a semi-automatic method for petroglyph segmentation for high-resolution 3D surface reconstructions. A comprehensive evaluation shows that our method is able to robustly segment petroglyphs with high accuracy and that the incorporation of 3D information is crucial to solve the segmentation problem. The presented method represents a major step towards the completion of a full 3D digital processing workflow of petroglyphs.

“…Furthermore, they propose a distance measure for petroglyphs based on the generalized Hough transform and demonstrate the performance of the distance measure on different petroglyph datasets. Landon and Seales [9] propose a system for 3D scanning and presentation of Puerto Rican petroglyhps.…”

The number of high quality images of rock panels containing petroglyphs grows steadily. Different time-consuming manual methods to determine and document the exact shapes and spatial locations of petroglyphs on a panel have been carried out over decades. The first step for classification and retrieval of petroglyphs is the segmentation of the images. In this paper, we present and evaluate an automated approach to segment petroglyph images.

“…Some methodologies describe how to process image data captured using the highlight capture method, the Highlight RTI methodology (Reflectance Transformation Imaging) (http://culturalheritageimaging.org/About_Us/CHI_Team/). Other approaches are sought involving video sequences or a set of 2D images for reconstructing a three-dimensional scene Liamas, et al, 2016;Lerma and Muir, 2014;Koutsoudis, et al, 2013) or cases which require an expensive and sophisticated 3D inspection system, such as laser triangulation scanner (Landon and Seales, 2006; http://scann3d.smartmobilevision.com). There are also some experimental software that include machine vision algorithms which apply page layout analysis, text line extraction, character recognition, and information retrieval (Stanco et ali, 2012).…”

This paper presents a pipeline that has been developed to acquire a shape with particular features both under the geometric and radiometric aspects. In fact, the challenge was to build a 3D model of the black Stone of Palermo, where the oldest Egyptian history was printed with the use of hieroglyphs. The dark colour of the material and the superficiality of the hieroglyphs' groove have made the acquisition process very complex to the point of having to experiment with a pipeline that allows the structured light scanner not to lose the homologous points in the 3D alignment phase. For the texture reconstruction we used a last generation smartphone.
