Abstract:
An optic flow sensor comprising:a plurality of photoreceptors, said photoreceptors generating a plurality of photoreceptor signals; a plurality of feature detector arrays, each said feature detector array receiving as input said photoreceptor signals, and each said feature detector array generating a plurality of feature signals; a plurality of optic flow measuring circuits or algorithms, each said optic flow measuring circuit or algorithm receiving as input one said plurality of feature signals, and each said optic flow measuring circuit or algorithm generating an optic flow measurement signal, whereby said plurality of optic flow measuring circuits or algorithms generates a plurality of optic flow measurement signals; and a fusion circuit or algorithm receiving as input said optic flow measurement signals, and generating a final optic flow signal from said optic flow measurement signals, whereby said final optic flow signal is a robust measurement of the optic flow as seen by said photoreceptors.
