Exsiting calibration methods are classified as ( 1 ) methods using point targets and distributed targets ; ( 2 ) methods using only distributed targets and ( 3 ) methods using only point targets . then the typical algorithms of every methods are given in which those of method ( 1 ) and ( 2 ) are modified based on a quantity of literatures 然后在众多算法中挑选了三种技术的典型算法,在综合多篇文献的基础上,给出修正的混合点目标和分布目标的定标算法:对所选的分布目标算法本人进行了修正,并给出了这个修雁的算法;点目标算法则按照原文献给出。
