Abstract

Utilizing compound eye camera array to capture multiple images for field-of-view stitching is one of the methods to acquire panoramic images. To address the issue of time-consuming stitching, this paper introduces a GPU-accelerated multi-image registration algorithm that significantly expedites image registration. The stitching process for each 10 sub-images takes approximately 0.6 seconds, achieving a tenfold improvement in speed compared to traditional CPU-based registration methods. In addition, for the contradiction between image field of view and image clarity, this paper constructs a principle prototype of 2×5 compound eye camera array. Using prime lens with a focal length of 85mm, while ensuring the image field of view reaches 90°, the angular resolution of the imaging can also achieve 0.06mrad. Finally, 120 megapixel stitching result can be obtained.
