Single-Row Superposition-Type Planar Compound-like Eye for Motion Recovery

How can the compound eye of insects capture the prey so accurately and quickly? This interesting issue is explored from the perspective of computer vision instead of from the viewpoint of biology. The focus is on performance evaluation of noise immunity for motion recovery using the single-row superposition-type planar compound-like eye (SPCE). The noise simulates possible ambiguity of image patterns caused by either environmental uncertainty or low resolution of the CCD device. Results of extensive simulations indicate that this special visual configuration provides excellent motion estimation performance regardless of the magnitude of the noise. It should be noted that any type of filters is not implemented in this study. The increase of the number of the CCD camera significantly reduces errors of motion recovery of the ego-translation. This discovery lays the basic foundation in terms of engineering approaches for the secret of the compound eye of insects.
