Abstract

We present a novel binocular imaging system for wearable devices incorporating the biology knowledge of the human eyes. Unlike the camera system in smartphones, two fish-eye lenses with a larger angle of view are used, the visual field of the new system is larger, and the central resolution of output images is higher. This design leads to more effective image acquisition, facilitating computer vision tasks such as target recognition, navigation and object tracking.

Keywords: binocular vision; fish-eye lens; wearable device.
