摘要
对多传感器系统预处理部分的灵敏度、选择性、精度及分离性作了全面分析,并引用矩阵范数证明了估计精度和分离性的上界。这些上界揭示了精度和分离性与设计阵的条件数[Cond(B)]以及设计阵偏离值δB和随机变量ε之间的关系。这表明,欲提高多传感器系统的估计精度,可通过控制Cond(B)。
The sensitivity,selectivity,accuracy and separability for the image pre processing circuit of multi sensor system are analysed completely and the upper bounds of the accuracy and sparability are obtained using the matrix norm.Those bounds expose the relations among the accuracy and separability,the condition number (Cond( b )) and deviation δ b of the design matrix and the diturbing random variable ε ,Which shows that the estimate of the accuracy can be restricted to a certain level by the control of Cond( b ), δ and ε .
