    Based on the variable resolution mechanism of human retina and the imaging principle of parallel compound eye, a hybrid bionic imaging system with multi-resolution is proposed to reduce data redundancy and to balance large field of view, high resolution and high efficiency. Given the consideration of both curved and plane surface on the layout, the imaging system included three layers in which the eleven cameras are divided into four groups to obtain images with four different resolutions. Two imaging experiments under the conditions of long distance of 100 m and short distance of 10 m are carried out, the results indicate that the total field of view reaches 150.8°×37.8° as keeping high resolution in the fovea. Moreover, the results of multi-resolution imaging experiments show that the system reduces the image resolution from the central field of view to the edge field of view gradually, and the amount of stitched image data with four-level resolution is reduced 17.2 times of data redundancy compared to the high-resolution image with total field of view.
