In this paper, a new points matching method for 3-D object recognition and location is presented. The global consistent match can be obtained by means of this method with simple calculating of distance and quaternary determinant, so model test is not necessary. 本文提出一种识别与定位三维物体的基于模型的点匹配法,这种方法只需要简单的距离计算与四阶行列式计算,就可获得物体与模型的全局一致性匹配,因此不需要进行模型检验。
