摘要
由于地面立体摄影测量能够真实、详尽地记录摄影瞬间客观景物的形态，具有良好的量测精度和判读性能，因此得到了广泛应用。但常规地面立体摄影测量需要有一定宽度的场地来布设基线，当在一些狭长地带或在线性工程中，摄影测量将受到限制。为此本文对等偏摄影测量的极端形式─—平行摄影测量进行了深入研究，并进行了大量实验，得到如下结论：在狭长地带，平行摄影测量的精度远高于正直地面立体摄影测量。
the ground three-dimension photogrammetry can record the pattern of objective scenery in photograph instant really and strictly, which have nice measuring precision and distinguish function, so which is applied widely. But the conventional ground three-dimension photogrammetry need some wide field to arrange baseline, the method is restricted in the narrow or linearity engineering. in this paper, the parallel photogrammetry is studied deeply which is a exceeding type of isosceles photogrammetry, and a lot of experiment is made. The conclusion is: the precision of parallel photogrammetry is higher than the straight ground three-dimension photogrammetry in narrow field.
