Paper Abstract

In order to solve the problem that the large field of view and high resolution of the traditional single aperture optical system are difficult to realize at the same time, a curved compound eye system including a three-ring lens group is designed. Firstly, the relationship between the field of view of the sub-eye system and the total field of view is studied, and the arrangement of the sub-eyes is obtained. Then, according to the object image conjugate relationship between the incident window and the exit window, we obtained a geometric model of sub-eye stitching. The compound eye system designed by this method has a full field of view of 79.5°. The angular resolution of the central system is 0.01°, the edge system is 0.017°. The system is simulated and verified by the optical design software ZEMAX. Finally, the feature points of each sub-eye image are extracted by SIFT(Scale Invariant Feature Transform) algorithm. The extracted feature points are accurately matched by RANSAC(Random Sample Consensus) algorithm, Then we use a weighted average algorithm to splicing the image of the sub-eye. This research further promotes the application of bionic compound eye imaging systems.
