Acquiring Complete and Editable Outdoor Models from Video and Images

想象一下，你可以把相机带出门，用它来捕捉你周围世界的3D模型。整个景观，包括山谷和丘陵充满了树木，河流，瀑布，草地，云;海边与海浪滚到海岸在这里和岩石上的碰撞;城市环境完成与杂项，如灯柱，阳台，和现代生活的碎片。想象一下那些看起来和动作都像真实的东西的模型。您可以使用模型来构建自己的新场景，您可以根据需要控制这些场景，并以您喜欢的方式进行渲染。您可以放大以查看细节，缩小以获得广泛的印象。这是一个令人印象深刻的愿景，并且远远超出了当前的专业知识。我们的计划是朝着实现这一愿景迈出重要一步。我们将使用户能够使用视频和图像来捕获选定类型的大规模场景，并使用模型树，喷泉，街道设施等填充它们，再次仔细选择对象的类型。我们将提供能够识别摄像机所处环境以及该环境中物体的软件，从而自动创建3D运动模型。这将证明对我们的目标用户群非常有用，即英国的创意产业：电影，游戏，广播。户外场景建模既昂贵又耗时，行业认识到视频和图像是制作模型的绝佳来源。为了进一步帮助他们，我们将开发软件，利用他们目前的做法，获取调查拍摄的场景，使所有数据都在许多层次的细节使用。最后，我们将把我们所有的开发都整合到一个单一的系统中，显示完整的户外环境的采集，编辑和控制更近了一步。

Imagine being able to take a camera out of doors and use it to capture 3D models of the world around you. The landscape at large, including valleys and hills replete with trees, rivers, waterfalls, fields of grass, clouds; seasides with waves rolling onto shore here and crashing onto rocks over there; urban environments complete with incidentals such as lamposts, balconies, and the detritus of modern life. Imagine models that look and move like the real thing. Models that you can use with to make up new scenes of your own, which you can control as you please, and render in how you like. You can zoom into to see details, and out to get a wide impression.This is an impressive vision, and one that is well beyond current know-how. Our plan is to take a major step towards meeting this vision. We will enable users to use video and images to capture large scale scenes of selected types and populate them with models trees, fountains, street furniture and such like, again carefully selecting the types of objects. We will provide software that recognises the sort of environment the camera is in, and objects in that environment, so that 3D moving models can be automatically created.This will prove very useful to our intended user group, which is the creative industries in the UK: films, games, broadcast. Modelling outdoor scenes is expensive and time consuming, and the industry recognises that video and images are excellent sources for making models they can use. To help them further we will develop software that makes use of their current practice of acquiring survey shots of scenes, so that all data is used at many levels of detail. Finally we will wrap all of our developments into a single system that shows the acquisition, editing and control of complete outdoor environments is one step closer.
