©作者。在这篇文章中，我们评估多项式纹理映射（PTM），反射变换成像（RTI）内的技术，在巴西南部的一组前哥伦布岩石艺术面板的应用。我们的案例研究，Avencal 1岩石艺术网站（Urubici，Santa卡塔里纳州），是巴西南部高地最大和最知名的网站之一。这项研究是自50年前记录以来首次对该网站进行详细分析。与之前的草图相比，使用PTM制作的记录更加完整。此外，它作为一种勘探工具的实用性首次揭示了多个侵蚀图案的存在。解释PTM数据，我们认识到面板的几个新的方面，已经被忽视。公布的计划和面板之间的差异进行了说明，因为是假设的生产序列的特定面板和多种技术的雕刻使用在Avencal 1。根据我们的研究，很明显，PTM具有分析和保护前哥伦布岩石艺术和超越的应用。本文附有我们在Urubici项目中产生的数据集，该数据集被广泛引用。数据文件由考古数据服务处托管。
© Author(s). In this article we evaluate the application of Polynomial Texture Mapping (PTM), a technique within Reflectance Transformation Imaging (RTI), to a group of preColumbian rock art panels in southern Brazil. Our case study, the Avencal 1 rock art site (Urubici, Santa Catarina state), is one of the largest and most recognised sites in the southern Brazilian highlands. This study is the first detailed analysis of the site since it was recorded five decades ago. The record produced with PTM is more complete when compared with preceding sketches. Furthermore, its utility as a prospection tool is underscored by revealing for the first time the existence of multiple eroded motifs. Interpreting the PTM data, we recognise several new aspects of the panels that have gone unnoticed. Discrepancies between the published plans and the panels are illustrated, as are hypothesised sequences of production for specific panels and multiple techniques of engraving used at Avencal 1. Following our study, it is clear that PTM has applications for both analysis and conservation of preColumbian rock art and beyond. This article is accompanied by the dataset produced from our project in Urubici, which is referred to extensively. The data files are hosted by the Archaeology Data Service.
