用于确定表示以铰接线形式表示的实体的至少两个肢体的运动的参数的值的方法和系统

Method and system for determining the values of parameters representative of a movement of at least two limbs of an entity represented in the form of an articulated line
Abstract:
A method determining values of parameters representing a movement of an entity represented by an articulated chain, by a sensor assembly including at least one sensor for a parameter representing an orientation of a first segment of the articulated chain, the method including: reception of an orientation value measured and supplied by the orientation sensor; estimation of a value of at least one first parameter representing a movement of the first segment by processing the orientation value; and, based on a predetermined movement model of the articulated chain, as a time change model, including at least one relationship of time dependency between the at least one first parameter and at least one other parameter representing a movement of another segment of the articulated chain: estimation of a value of the at least one other parameter by application of the time change model to the estimated value of the at least one first parameter.
Abstract(Chinese):

一种确定表示由铰接链表示的实体的运动的参数值的方法，所述传感器组件包括至少一个传感器，所述传感器用于表示所述铰接链的第一段的取向的参数，所述方法包括：接收定向 由定向传感器测量和提供的值; 通过处理所述取向值来估计代表所述第一段的移动的至少一个第一参数的值; 并且基于所述铰接链的预定移动模型，作为时变模型，包括所述至少一个第一参数与表示所述铰接链的另一段的运动的至少一个其它参数的至少一个时间依赖关系 ：通过将时间变化模型应用于至少一个第一参数的估计值来估计至少一个其他参数的值。
