象基线对立体模型下地形高差测量影响的分析及高差计算公式的修正

The Effect of the Length of the Image Base Line on the Measurement of Height Difference under Stereomodel

测量结果的对比分析表明,象基线对立体模型下的地形高差测量没有影响,现用高差计算公式不能给出正确的结果。提出了新的高差计算公式。

The contrast analysis of measured results showed that the length of the image base line had no effect on the measurement of height difference under stereomodel. The current equation used to calculate the height difference could not meet the correct answers. The new equation which can give precise results is suggested.
