航空象片局部比例尺测定的新方法

A NEW WAY TO NEASURE THE PARTIAL SCALE OF AERIAL PHOTOS

以往测定航空象片局部比例尺均使用单张象片，本文介绍利用立体象对进行测定的原理和操作方法。

Almost all the partial scale of aerial photos was measured by using single photo till today.Znstead of that a new method including its theory by using a pair of stereosco pic photos is introduced in this article.
