摘要
介绍了最大似然交替投影算法的基本原理,通过对单次快拍条件下最大似然交替投影算法的化简,提出了一种新的简化的最大似然交替投影算法,使运算量大大减少。最后结合某课题,采用新的简化后的最大似然交替投影算法实现了测高模块的设计,使用高性能的数字信号处理器(TS201)和FPGA完成算法的实现,并给出了工程实现的方法。
With the basic principle introduced,a new and simplified maximum likelihood alternating projection algorithm is presented by simplifying the algorithm in the condition of the single snapshot to greatly reduce the amount of calculation.In combination with a project,the simplified algorithm is adopted to implement the height-finding module through the high-performance DSPs(TS201) and the FPGAs with the implementation of the engineering given.
