构建有效的地质灾害监控系统有助于提升主动应对灾害的能力，对国民生产生活具有重要作用。多媒体传感器网络作为一种新型数据获取手段，具有易配置、低功耗、低成本、精确感知等优势，已在灾害监控领域得到广泛关注。然而，受部署环境特殊、无线多跳传输、及节点处理能力受限等影响，现有多媒体传感器网络的定位及覆盖控制技术尚不能满足复杂地质灾害环境安全监控的需求。本申请项目拟以多媒体传感器网络为突破口，探索满足地质灾害监控所需要的节点定位、覆盖控制及场景重建技术。主要研究内容包括：（1）满足复杂地质环境监控需求的高可靠定位技术；（2）满足复杂地质环境监控需求的多媒体传感器网络覆盖控制技术；（3）满足复杂地质环境监控需求的图像拼接与场景重建技术。研究成果将为地质灾害监控及场景重建提供新的解决方案，具有重要的理论意义与应用价值。

Constructing an effective geological disaster monitoring system helps people to deal with the disasters proactively, and plays an import role for domestic production and living. Wireless multimedia sensor network (WMSN) is a novel data gathering method with easy configuration, low-power, low cost and accurate perception characteristics, which has attracted much attention from the field of disaster monitoring. However, due to the complex deployment environment, the wireless multi-hop communication, and the constraints of node processing capacity, existing localization and coverage schemes cannot satisfy the needs of geological disaster monitoring. Considering those special characteristics of the geological environment, we take WMSN as the breakthrough, and exploit the localization, coverage and scene reconstruction techniques in this project. The research contents mainly include: (1) reliable localization schemes satisfying the needs for monitoring complicated geological environment; (2) coverage schemes satisfying the needs for monitoring complicated geological environment; and (3) image stitching and scene reconstruction techniques satisfying the needs for monitoring complicated geological environment. The research results will provide a new solution for monitoring geological catastrophes, and will provide important theoretic meaning as well as application value.
