For global registration of rigid body , based on analysis of the principal axes method , by making use of automatic and very fast nature , and easy implementation of the method , a registration method of principal axes - information is presented to remedy drawback of coarse result 針對(duì)單模剛體全局配準(zhǔn),先分析了基于主軸配準(zhǔn)法的配準(zhǔn)原理,再在此基礎(chǔ)上,利用其計(jì)算速度快、全自動(dòng)化以及容易實(shí)現(xiàn)的優(yōu)點(diǎn),并針對(duì)其配準(zhǔn)精度不高的不足,提出了一種基于主軸信息的配準(zhǔn)方法。
