Panorama mosaic in bionic compound eye visual system

A bionic spherical 9 compound eyes visual system was designed through simulating visual mechanism of insect compound eye, and a panoramic image mosaic algorithm was proposed. Firstly, feature points were extracted and matched by using the scale invariant feature transform (SIFT) image-matching algorithm. Secondly, the transformation matrix H was computed by random sample consensus (RANSAC) algorithm and Levenberg-Marquardt (LM) algorithm. Finally, the panoramic image was completed with improved weighted smoothing algorithm. The experimental results show that the whole seamless panorama mosaic process of multi-view image sequence is completed automatically, and the field of view is enlarged in multi-directions, which makes up the defect of the traditional wide screen panorama.
