设计并实现了基于图像检索的地标识别系统。该系统通过捕捉地标的视觉特征，帮助游客或使用者更好地理解图像的内容并同时提供图像拍摄的地理位置信息。首先根据提取的SURF特征搜寻地标在数据库中的最优匹配，然后根据最优匹配结果给出输入地标在地图中的位置。系统采用的层次化数据库结构和分级检索方式，使得检索效率比传统的遍历检索方式提高30％。大量实验证明文中提出的算法具有鲁棒性和高准确性，该系统已在高校内部地标识别中测试使用成功。

A landmark recognition system based on image retrieval is designed and implemented. Through capturing the visual characteristics of the landmark picture, the system helps tourists or users to understand content of picture better and provides the location information of the picture. Firstly, the system finds the best match in the landmark database based on features extracted by SURF. Then, the location information of the retrieved image is shown in the local map. The system adopts a hierarchical database structure and a hierarchical retrieval scheme, as a result of which the retrieval efficiency is raised by 30%. Numerous experiments show robustness and accuracy of our system. The system has been successfully applied in recognizing local landmarks of colleges.
