摘　　要：在航片水平、地形起伏的条件下 ,当立体象对的两地主点高程不同时 ,左右邻片的象基线不相等 ;地主点高程相对较低的航片 ,象基线较长 。When the elevations of land central points of stereopairs are different under the condition of airphotos being level and the topography being in relief,the image base lines of the stereopairs are unequal,and,the image base line of one of the airphotos having lower elevation is longer than that of having higher elevation,and with the elevation difference of two land central points of stereopairs increasing,the difference between the image base lines is becoming greater.

关 键 词：地形起伏 立体象对 象基线
