我们提出了一个支持风景照片本地化的系统。照片的定位是将相机参数分配给照片。这些参数包括相机的位置、方向、焦距和拍摄照片的胶片尺寸。该系统的一个应用是面向位置的搜索系统的元数据生成。该系统的目标照片是风景照片，使得照片中的地形具有足够的特征来指定位置。我们描述了摄影对象的特征和定义搜索问题的搜索区域。该系统以问题定义和初始解集合为输入，通过特定的算法对解进行改进。我们可以使用遗传算法和局部搜索算法作为算法。该系统的关键点是我们可以描述什么来定义搜索问题，以及系统搜索好的解决方案的效率如何。在理想条件下的两次评测实验表明，该系统具有足够的表现力，能够有效地找到合适的解。
We present a system which supports localization of landscape photographs. Localization of a photograph is to assign the camera parameters to the photograph. The parameters are the camera's position, direction, focus and film size to take the photograph. An application of the system is metadata generation for location oriented search systems. Target photographs for the system are landscape photographs such that terrain in the photographs is enough characteristic to specify the locations. We describes features of photographic objects and a search area to define a search problem. The system takes the problem definition and an initial solution set as its input, and improves the solutions by a specified algorithm. We can use a genetic algorithm and a local search algorithm as the algorithm. Key points to the system are what we can describe to define search problems, and how effectively the system searches good solutions. Two evaluation experiments under an ideal condition shows that its expressiveness is enough and the system can find appropriate solutions effectively.
