Computer-generated high-fidelity augmented reality visualisations ofproposed architectural developments can play a significant role inhelping a viewer understand the visual impact on the environment,especially in sensitive locations. Such interactive visualisations havethe potential to greatly improve both the initial design process, and thesubsequent planning application and public consultation processes. Thecurrent lack of robust automatic methods for acquisition of site contextgeometry, together with the performance demands of producinghigh-fidelity renderings in real-time, has meant the adoption of suchtechniques within the architectural industry has, to date, been limited.The proposed research represents a unique confluence of computer vision,high-fidelity rendering, and real-time 3D augmented reality techniques,only possible through the combination of strengths of the partners. Thenovel techniques we will develop in the areas of automaticreconstruction from wide-baseline images, image-based lighting, andreal-time global illumination, will be scoped by the demands of a realarchitectural application with our industrial partner Napper Architects,and English Heritage. Our techniques will be informed by the stringentfidelity requirements of a mixed-reality application suited to providingvisual impact assessment for sensitive developments.The research plan comprises four work packages which will be integratedto deliver a prototype demonstrator system which will support: theautomatic creation of an accurate 3D computer model of the developmentsite, interactive experimentation with different design and lightingscenarios, and interactive exploration by the general public of thevisual impact of the proposed development. The system will beextensively validated at a number of stages throughout the project usinga combination of comparisons with still images, video footage,ground-truth data and public consultation. During the lifetime of thisproject, our industrial partner Napper Architects will be engaged in asmall and defined sensitive architectural project with English Heritage.Models and data from these will be made available as a test case. Inaddition to the novel research outcomes, and prototype software fromthis project, we will develop new fidelity metrics for the benefitof the architectural, planning, and consultation communities.

计算机生成的高保真增强现实可视化的建议建筑发展可以发挥重要作用，帮助观众了解对环境的视觉影响，特别是在敏感的位置。这种交互式可视化有可能大大改善初始设计过程，以及后续规划申请和公众咨询过程。目前缺乏强大的自动方法来获取网站contextgeometrics，以及实时生产高保真渲染的性能要求，意味着在建筑行业内采用此类技术，到目前为止，受到限制。拟议的研究代表了计算机视觉，高保真渲染和实时3D增强现实技术的独特融合，只有通过合作伙伴的优势相结合才有可能。我们将在宽基线图像自动重建、基于图像的照明和实时全局照明领域开发的新技术，将与我们的工业合作伙伴Napper Architects和英国遗产一起，根据实际建筑应用的需求进行范围划分。我们的技术将受到适合为敏感开发提供视觉影响评估的混合现实应用程序的严格保真度要求的影响。研究计划包括四个工作包，这些工作包将被集成以提供原型演示系统，该系统将支持：自动创建开发现场的精确3D计算机模型，不同设计和照明场景的交互式实验，以及公众对拟议发展的视觉影响的互动探索。该系统将在整个项目的多个阶段进行广泛验证，使用静态图像，视频片段，地面实况数据和公众咨询的比较。在这个项目的生命周期中，我们的工业合作伙伴纳珀建筑师事务所将参与一个小型的和明确的敏感建筑项目与英国遗产。模型和数据，从这些将作为一个测试案例。除了新颖的研究成果，和原型软件从这个项目中，我们将开发新的保真度指标的建筑，规划和咨询社区的利益。
