Abstract

Abstract: The images sequence captured by UAV has the high resolution and high overlapping characteristics, so it is used in a wide range of scene reconstruction. However, the result of these state-of-art multi-view 3D reconstruction algorithms is unstable when dealing with large-scale UAV thousands of images. In this regard, the UAV low accuracy GPS / IMU parameters sequence was fused to the large-scale UAV image reconstruction process and the UAV sequence batched image reconstruction method was proposed. The image matching time and false matching number was reduced by using low-precision GPS / IMU priori information. Through the establishment of a polar graph and drawing the midpoint of the track multi-view, combined with low-accuracy GPS / IMU information, the global coordinate system rotation matrix of all the images was disposably solved, executing only when a bundle adjustment function, reducing the reconstruction optimization of time complexity. Experimental verification of this method ensures accuracy while improving efficiency.
