Abstract

Abstract: UAV sequence image has the characteristics of high overlap and strong topological connection. Aiming at the inefficient and unstable in processing the large-scale UAV images of the existing incremental 3D reconstruction algorithm, a 3D reconstruction method based on motion structure graph is proposed. The image matching index is established by using the geolocation information and IMU data to improve the image matching efficiency, and the random motion consistency algorithm is used to calculate the relative motion; motion structure graph is used to represent the "association" between images, and closed-loop detection algorithm is used to eliminate the false edges. Under the mapping relationship between Lie algebra and Lie group, the global motion of the image is solved at one time by 1 L paradigm and M estimation, and the beam adjustment is used only once. Experiments show that the proposed algorithm improves the efficiency and reconstruction result.
