摘　　要：系统介绍了像素工厂和海拉瓦数字摄影测量系统的空中三角测量特点,并通过实验比较了二者的性能。实验比较发现,基于两个系统的空中三角测量精度基本相同;执行效率方面,当测区数据量较大时,像素工厂更具有整体优势;而在小区域数据处理上,SOCET GXP更具灵活性。当测区影像超过150景时,建议在像素工厂中进行空中三角测量。The characteristics of aerial triangulation in pixel factory and Hailawa digital photogrammetry system was systematically introduced in this paper,and the performance of them was compared by experiment. Based on the experimental results,the accuracy of aerial triangulation based on two systems was basically the same. When the amount of data in the measurement area was large,the pixel factory had the overall advantage in efficiency aspects. However,SOCET GXP is more flexible in small area data processing. When the area image exceeds 150 views,this paper recommended aerial triangulation in pixel factory.
