人们普遍认识到,新技术可以在解释我们的文化遗产遗产方面发挥重要作用。这已经成为一个强大的工具,提供了更好地了解我们的过去,从而使我们能够瞥见我们祖先生活的环境。在这一领域,我们如何看待这种重建的环境是特别重要的,以便建立一个准确的解释,历史背景。然而,在任何考古场景的表示所需的视觉精度是严格相关的技术来可视化它。高动态范围(HDR)技术包括产生类似于人眼的视觉敏锐度的视觉效果的能力,特别是在极端照明条件下,如明亮的光线或昏暗的环境。在本文中,我们提出了一个古老的火焰光模拟方法和感知视觉用户的研究与HDR图像的罗马马赛克和壁画,照亮了该时期的灯具,位于最令人印象深刻的纪念碑之一的废墟中的Conimbriga,葡萄牙。通过这项工作,我们打算展示这种特殊的低强度罗马光的使用,与其他现代照明相比,如何影响受试者对古代文物的感知,并影响场景观看模式。
It is widely recognized that new technologies can play an important role in the interpretation of our cultural heritage legacy. This has become a powerful tool providing a better understanding of our past, and thereby, allowing us to attain a glimpse of the environments in which our ancestors lived. In this domain, the way we see such reconstructed environments is particularly important in order to establish an accurate interpretation of that historical setting. However, the desired visual accuracy in the representation of any archaeological scenario is strictly related to the technology used to visualize it. High Dynamic Range (HDR) technology encompasses the capacity to produce visual results similar to the visual acuity of the human eye, particularly in extreme lighting conditions, such as bright light or dim environments. In this paper we present an ancient flame light simulation method and a perceptual visual user study with HDR images of Roman mosaics and frescoes, illuminated by luminaries of that period, located in one of the most impressive monuments in the ruins of Conimbriga, Portugal. With this work we intend to demonstrate how the use of this particular low intensity Roman light, when compared to other modern illumination, affects the subjects' perception of ancient artefacts and influences the scenario viewing pattern.
