Abstract: In close-range photogrammetry, manually turning objects and taking highly overlapping images from multiple views is significant to complete 3D model reconstruction. However, the background of the images is inconsistent with the object in the process of turning, leading to the failure of bundle adjustment, and the deformation and incompleteness of object models. This paper proposes a complete 3D reconstruction method based on multi-view geometric consistency. We analyze the distribution pattern of rotation unit quaternion to judge whether the object is turned in the image pair and group the images. Based on the grouping results and the geometric consistency of feature point matching, we reconstruct object regions without the interference in the background of the images, improving the precision of aerial triangulation and obtaining complete mesh models. Experiments show that our method could improve the accuracy and completeness of 3D models effectively when the object has been overturned.
