Mosaic Algorithm for Aerial Remote Sensing Image and Its Accuracy Evaluation
Yang Bi · 2014
Small imaging coverage and big parallax angle make aerial remote sensing more difficult to image processing.This paper proposes an algorithm for aerial remote sensing image mosaic.The original image is corrected by perspective transform with estimating matrix which is determined by the relative attitude of two images.It solves the distortion problem caused by big parallax angle.Image registration is approached by the Scale Invariant Feature Transform(SIFT) algorithm and a method based on probability density.The image mosaic process is completed by the wavelet transform.Experimental result shows that the mosaic performance of this algorithm is better than traditional SIFT algorithm in different surface conditions.
