摘　　要：多传感器数据融合首先要解决误差配准问题,来估计系统偏差并消除它。把最小二乘理论运用于多传感器数据融合,能够得到系统偏差估计。分析最小二乘(LS)和广义最小二乘(GLS)的原理,并对两种算法进行了比较。Registration is a prerequisite process for the data fusion in multi-sensor system to estimate and correct systematic errors.Applying least squares to multi-sensor data fusion,we can get the estimation of system errors.This article discusses the technology of least squares and generalized least squares,and compare them at last.
