In this paper we present two petroglyphs of western sailing ships that were recently discovered on Rapa Nui (Easter Island). The far-reaching social ramifications of the arrival of the first Europeans have been discussed in a number of papers, but these newly found images allow for further insight into the effect their arrival had on the Rapanui population. Using structure-from-motion (SfM) macro photogrammetry we created detailed 3D images of the petroglyphs. This helped identify a hitherto unrecognised sense of accuracy and attention to detail employed in the depiction of a European ship by Rapanui artists. Their interest in the construction of European sailing ships, and reproductions thereof, are best understood in the context of the island's isolation and the lost traditions of building ocean-going canoes.

直视地平线：动态结构摄影测量法增强了对Rapa Nui（复活节岛）的船刻文字的理解

在本文中，我们介绍了最近在Rapa Nui（复活节岛）上发现的两艘西方帆船的刻在岩石上的文字。在许多论文中都讨论了第一批欧洲人到来的深远社会影响，但是这些新发现的图像使人们可以进一步了解他们的到来对拉帕努伊人口的影响。使用运动结构（SfM）宏观摄影测量法，我们创建了岩画的详细3D图像。这有助于确定迄今为止从未被认识到的准确性和对拉帕努伊（Rapanui）艺术家描绘欧洲船所采用的细节的关注。他们对欧洲帆船的建造及其复制品的兴趣，在该岛与世隔绝和失去建造远洋独木舟的传统的背景下得到了最好的理解。
