摘要: 提出了一种全新的数字近景摄影测量方法——旋转多基线数字近景摄影测量。该方法通过应用旋转摄影增大了摄影视场角,应用“多基线”的摄影方式增大了摄影交会角,提高了交会精度,并且解决了近景摄影测量中大交会角影像难以实现自动匹配的困难。同时,该方法将传统的区域网空中三角测量应用于近景摄影测量,用于影像外方位元素的解算,在提高精度的同时减少了外业工作量,提高了生产效率。

Abstract: A new method of digital close-range photogrammetry——panning and multi-baseline digital close-range photogrammetry,is presented.This method enlarges the intersection angle and improves the intersection precision by multi-baseline photography;enlarges the angle of view by panning photography,and resolves the difficulty of matching for images with large intersection angle.At the same time,this method applies the classic aerotriangulation and bundle adjustment to the close-range photogrammetry;we need more than three ground control points to compute the exterior orientation elements of all images.The experiments prove that this method can acquire the high accuracy and improves the production efficiency.
