摘要
针对大比例尺测图的精度要求,研究低空数码影像多视摄影测量的方法。根据计算机视觉的多视几何原理建立匹配的约束条件,实现多视匹配;利用低空数码影像的重叠度大的特点,建立多基线立体,进行多片空间前方交会。不同重叠度的立体像对空间前方交会和多片空间前方交会的实验结果证明,多视摄影测量能够提高有效低空数码影像的摄影测量精度。
To meet the potential demand of large scale mapping, a multiview photogrammetry approach was presented for low altitude digital images. A multiview matching was carried out under a restricted condition derived from multiview geometry in computer vision. Multiple image spatial forward intersection method was adopted to deal with multi-baseline stereo from low altitude digital images with large overlapping. Experiments on spatial forward intersection with stereo pairs of different overlapping and multiple images indicate that multiview photogrammetry is able to improve the photogrammetric accuracy of low altitude digital images.
