Multiple Cartridges Improve Edge Detection Algorithm for Fly Inspired Vision System

The compound vision system of a common housefly, Musca Domestica, has better motion detection and tracking capabilities as compared to traditional camera systems based on human vision. Therefore, a compound vision sensor that mimics the vision of a common housefly is far more advantageous in applications requiring object detection and obstacle avoidance. Recent proof-of-concept has shown that compound vision sensors possess motion hyperacuity characteristic of the fly's visual system with instantaneous edge detection capability; without the need of a computer processing system. However, the current Musca domestica inspired vision system, with one cartridge, cannot detect edges at the center of its field of view. In this paper, multi-cartridge sensor designs have been presented that allow more robust edge detection and orientation capability to the compound vision sensor design.
