Research on Image Fully Automatic Mosaic Method with Large Rotation Angle from Unmanned Aerial Vehicle
摘要
Abstract
Images with large rotation angle from low altitude Unmanned Aerial Vehicle(UAV) with weakness stability cannot realize automatically mosaic using the" traditional methods with geo-referenced orthographic images, in this paper, an image mosaics technique with Scale Invariant Feature Transform(SIFT) and multi-resolution spline merging is proposed for low attitude UAV images. A fast and batch image distortion correction algorithm based on single image distortion look-up table is presented for multiple images. A novel homograph-constrained image matching algorithm based on SIFT feature is proposed to calculate the optimal transformation matrix between overlapping images. A multi-resolution spline mosaics technique with optimal transformation matrix of overlap images is presented. Experimental result shows that the proposed method can obtain a large number of stable correspondences and transformation matrix of overlap images for further seamless image mosaic, which can be useful for fast and automatic images mosaic from low altitude UAV with large rotate angle and instability.关键词
