摘要
本文讨论了对刚体群点进行动态预测的建模方法.该方法尽可能地保持群点间相互联系的整体性,仅对群点运动中的独立运动因素进行建模.当刚体群点集合中样本点数量很大时,它可以使建模工作量大幅度下降,同时使模型的精度和可靠性得到更好的保证.
This paper deals with a modeling method for dynamic forecast of a rigid set of samples in a multi dimensional space.This method can keep the relations of the sample points to maintain the entirety of the set as well as possible.What's more,only the independent factors of this rigid set will be at work by using stochastic models.In this way,a large amount of modeling work can be cut down,especially when the number of sample points in the rigid set is very large.At the same time the precision and reliability of the forecast are able to be better ensured.
