A heterogeneous data integration solution based on XML scheme is proposed to solve the information retrieval inconvenient problem which comes from that structured data generated by the video parsing cannot be merged into video recording file in intelligent video surveillance system. By integrating the XML files exported from the surveillance database with the associated video files in hetero-geneous way,this solution enable users to access the monitoring data and video files through a unified interface. Firstly,an unified plat-form for data integration and user queries is designed after the research and analysis of related technology. Secondly,an experiment for ve-hicle information retrieval in HD bayonet scene is carried out. The result shows that this method not only achieves the retrieval of video files based on keywords,but also realizes the video file-based information retrieval. This technology makes the free migration of data pos-sible and offers the ability of off-line information retrieval based on the video file. Hence,it is very practical.%针对智能视频监控中视频解析产生的结构化数据不能集合存储到视频录像而由此带来的信息检索不便问题，文中提出了一种基于XML的异构数据集成解决方案。它主要通过将监控数据库中的检索数据导入XML文件后和关联视频文件进行一体化的异构数据存储，使用户可以通过统一的接口来实现对监控数据和视频文件的访问。首先在对相关技术进行研究和分析的基础上，设计了一个统一的数据集成和用户查询平台；然后在高清卡口场景下，针对车辆信息检索进行了实验。结果表明，该方法不仅实现了基于关键词的视频文件检索，也实现了基于单一视频文件的信息检索。该技术提高了数据的自由迁移能力，可以实现基于视频文件的离线信息检索，因此具有极高的实用性。
