In recent years, three‐dimensional (3D) modelling with photogrammetry and enhancement methods from computer graphics communities have been used with excellent results for studies of rock art engravings. However, despite their abundance, most Atlantic rock art elements in the Iberian Peninsula have not yet been geometrically documented in 3D. The aims of this study include deepening the application of imaged‐based modelling, digital 3D model post‐processing, and diffusion tools in determining an accessible and straightforward workflow that is accessible for amateur and professional rock art researchers. The proposed workflow makes possible the prospection, documentation, enhancement, and diffusion of this heritage phenomenon in a massive collaborative manner. Thus, a representative sample of Atlantic rock art was documented using an affordable and time‐optimized methodology for image‐based modelling with free software at all stages of the process. This methodology improves the promotion of documentation of heritage through professional and social collaboration. The diffusion can be performed from two‐dimensional (2D) vectorizations from the rendering of MeshLab Radiance Scaling enhancement and automatic vectorizers or from the direct publication of enhanced 3D models, which are currently possible with platforms such as Sketchfab.

用于雕刻的3D虚拟分析和矢量自动跟踪的可访问，灵活且低成本的工作流程：大西洋岩石艺术分析

近年来，通过摄影测量法和计算机图形学界的增强方法进行的三维（3D）建模已用于岩石艺术雕刻研究，并取得了优异的成绩。但是，尽管数量众多，但伊比利亚半岛中的大多数大西洋岩石艺术元素尚未在3D中进行几何记录。这项研究的目的包括加深基于图像的建模，数字3D模型后处理和扩散工具在确定可供业余和专业岩石艺术研究人员使用的可访问且直接的工作流程中的应用。拟议的工作流程使以大规模协作的方式对该遗产现象的勘查，记录，增强和传播成为可能。从而，在整个过程的各个阶段，使用免费软件对基于图像的建模使用了一种价格合理且经过时间优化的方法，对大西洋岩石艺术的代表性样本进行了记录。这种方法论通过专业和社会合作促进了遗产文献的推广。扩散可以从MeshLab Radiance Scaling增强和自动矢量化器的渲染中的二维（2D）矢量化执行，也可以从增强型3D模型的直接发布进行，这些功能目前可以通过Sketchfab等平台实现。
