A challenging aspect of visibility studies is visual acuity, which concerns the clarity of vision within a given space in relation to variables such as spatial geometry, lighting conditions, the physical properties of the viewed object, or the familiarity of viewers with the target. Our research proposes a novel approach to visibility studies, based on visual acuity and its related pipeline, which integrates qualitative and quantitative aspects such as the cultural background of viewers, the illumination values of space, contrast, and size of objects of interest as well as their meaning and context. The proposed pipeline relies on 3D documentation of the investigated space, light measurements, research in optics, trigonometry calculations, and 3D GIS set against images and architectural space. The method's effectiveness is demonstrated in the study of the iconography of the Cathedral of St. John the Theologian in Nicosia, Cyprus, the work hypothesis being that the church's spatial organization, choice of scenes, and level of detail were carefully planned to establish visual narratives with strong political and religious connotations and to overall dictate the ways the building was accessed and experienced. The method can be broadly applied for visibility analyses in a variety of case-studies in closed spaces.

用视力评估遗产地的视觉感知

能见度研究的一个具有挑战性的方面是视敏度，它涉及给定空间内的视觉清晰度，与空间几何、照明条件、观察对象的物理特性或观察者对目标的熟悉程度等变量有关。我们的研究提出了一种基于视敏度及其相关管道的能见度研究的新方法，该方法整合了定性和定量方面，例如观众的文化背景、空间照明值、对比度和感兴趣对象的大小以及它们的含义和上下文。拟议的管道依赖于所调查空间的 3D 文档、光测量、光学研究、三角计算以及针对图像和建筑空间设置的 3D GIS。方法' 对塞浦路斯尼科西亚神学家圣约翰大教堂肖像的研究证明了它的有效性，工作假设是教堂的空间组织、场景选择和细节水平都经过精心策划，以建立视觉叙事强烈的政治和宗教内涵，并总体上决定了进入和体验建筑物的方式。该方法可广泛应用于封闭空间中各种案例研究中的可见性分析。精心策划的细节水平和细节水平，以建立具有强烈政治和宗教内涵的视觉叙事，并从总体上决定进入和体验建筑物的方式。该方法可广泛应用于封闭空间中各种案例研究中的可见性分析。精心策划的细节水平和细节水平，以建立具有强烈政治和宗教内涵的视觉叙事，并从总体上决定进入和体验建筑物的方式。该方法可广泛应用于封闭空间中各种案例研究中的可见性分析。
