中文摘要： 针对无信标环境下具有非规则运动形态的人员定位需求，特别是消防人员在复杂建筑火灾现场实时定位的需求，本项目提出利用人体运动零瞬态特征抑制惯性器件长时漂移的定位方法。研究基于惯性测量组合（IMU）和智能信息融合的复杂环境下人体非规则运动行为的认知，有效判断人体行为状况；研究人体线运动和角运动零瞬态特征，融合多部位传感信息并确定零瞬态判别准则；建立动态环境下融合人体非规则运动行为特征的惯性定位方程；研究惯性定位方程零瞬态触发修正状态和触发修正关系，以及这种非线性、时变、变采样时间的特殊系统的求解方法。在此基础上，形成人体非规则运动行为认知与自主定位的理论与方法。从而以基础研究突破复杂建筑内部/灾难现场人员准确定位的技术瓶颈，对无信标环境下人员实时精确自主定位具有广泛而重要的科学意义与应用价值。

英文摘要： Aiming to the requirements and the key technology bottleneck of the personal location specially a firefighter whose movement would be abnormal in a land-mark-free condition, this application proposes a location approach that uses the zero transient state feature of body movement to inhibit the long-time drift of inertial measurement unit (IMU). The cognition and behavior estimation on body abnormal movement is detailed on the basis of IMU and intelligent information fusion firstly. Then the zero transient states of body translation and rotation is analyzed, and the judgment criterion for zero transient states is provided by information from multiple body regions. The inertial location equations constrained abnormal body movement feature in dynamic environment is set up, thus the trigger correction relationship of zero transient state for the location equations is presented. Finally the solution for this nonlinear, time-varying and variable sampling time system is discussed. Therefore, this fundamental research on abnormal body movement cognition and autonomous location theory is useful for break through the technical bottleneck of personal location in a complex building or disaster scene, and has wide and important scientific and application value for personal real-time precise autonomous location in land-mark-free environment.
