Identification method and device for unmanned aerial vehicle to patrol river channel floating objects

The invention provides a recognition method and device for unmanned aerial vehicle patrol of river channel floating objects. The method comprises the following steps: reading an image of a to-be-detected river channel collected when an unmanned aerial vehicle executes field flight; extracting a hue layer from the image of the to-be-detected river channel; performing binarization processing on the tone layer; according to the binarization data obtained by the binarization processing, determining whether the river channel floaters exist in the to-be-detected river channel; and if it is determined that the riverway floaters exist in the to-be-detected riverway, counting coordinate position information of each riverway floater. According to the recognition method and device for unmanned aerial vehicle patrol of the river channel floating objects, the coordinate position information of the floating objects is determined by automatically analyzing, recognizing and positioning the river channel floating object image
