摘　　要：根据几何成像原理建立起双CCD立体视觉系统的数学模型,但是立体视觉测量中同名点的准确匹配始终是一个难题。利用基于区域匹配的方法,在使两CCD关于XZ平面绝对对称,即同名点在OXYZ坐标系下x值相同的前提下,提出了一种将二维面上平移范本转变为在一维线段上平移范本进行同名点识别的方法,解决了区域匹配方法计算量大的问题,提高了同名点匹配的速度和精度。A mathematical model for double-CCD stereoscopic system was set up according to geometrical imaging principle. Homonymy point matching in stereoscopic vision measurement remains a difficult problem. Based on the method of area matching, it is presented for a method of homonymy point matching that the template can move only in the corresponding one-dimension line instead of two-dimension area by restricted the fixed position of double-CCD. This method decreased the long computing time in the method based on area and improved the speed and precision of homonymy point matching.
