摘要
数字近景影像的绝对定向同经典的航空摄影测量有很大的不同,为提高数字近景影像的绝对定向精度,提出了一种基于逐次相关条件平差模型的近景影像绝对定向方法。首先给出计算绝对定向参数初始值的严密公式。然后利用绝对定向方程的严密线性化形式进行逐次相关条件平差。同传统的基于经典间接平差的绝对定向方法相比,该方法可有效提高绝对定向的精度,非常适合于数字近景影像的绝对定向。
The method of absolute orientation between conventional aerial photogrammetry and digital close - range photogrammetry is very different. In order to improve the precision of absolute orientation of digital close - range photogrammetry, a new method based on correlative condition adjustment was proposed. Firstly, a rigid formulation was presented to determine the initial values of absolute orientation elements. Then, relative condition adjustment was performed based on the linear equation of absolute orientation. Test results indicated that this method could improve the accuracy of absolute orientation of digital close - range photogrammetry effectively and fit well for digital close -range images.
