Block Harris Based Mosaic Method for Aerial Video

A mosaic method for aerial video based on the block Harris feature was proposed,which is able to cope with the problem of high computation and low accuracy of the current mosaic methods.This method overcomes the shortages of the traditional SIFT method,since it can save the matching time and improve the accuracy.First,block Harris feature extraction method is used to obtain a better distributed of the feature point.Then,pyramidal Lucas-Kanade algorithm is used to match the feature points.After that,an improved RANSAC method is used to calculate the affine parameter accurately.Experimental results show that our method can do mosaic quickly and correctly.
