针对异类传感器数据融合空间配准问题,利用极大似然法对多传感器系统模型进行分析,推导出配准参数的估计值,以毫米波雷达/红外传感器复合制导为例,对空间配准算法进行了仿真,仿真结果具有较快的迭代收敛速度和较好的配准效果,满足了异类传感器融合实时性和精确度的要求。

The spatial registration for data fusion of different sensors was studied. The multi-sensor system was analyzed by using maximum likelihood method,and the estimated registration parameters were deduced. Taking the composite guidance of millimeter wave radar with infrared sensor as an example,we made a simulation to the spatial registration algorithm. The results proved that the algorithm has rapid iterative convergence speed and fine registration effect,which may satisfy the real-time and precision requirement to data fusion of different sensors.
