This invention discloses a method and device for precise fish feeding based on water surface ripple induction and visual feedback. The method involves artificially generating physical ripples on the water surface to simulate live bait disturbance and induce fish aggregation. Feeding is then initiated, and a real-time video stream is acquired. After image enhancement and feature map construction, a background suppression model is used to remove water ripple interference and accurately extract the salient areas of the feed. Subsequently, the instantaneous feed drift flux crossing the visual warning line and the cumulative loss within the studied time window are calculated. Once the cumulative loss exceeds a preset threshold, it is determined that the fish have stopped feeding, and feeding is stopped. This invention effectively stimulates the fish's appetite for artificial formulated feed through physical means and constructs a closed-loop feedback control mechanism based on the drift flux of uneaten feed. It solves the problems of low fish feeding willingness, high false detection rate, and difficulty in accurately controlling the feeding amount in traditional feeding methods, significantly reducing feed waste and water pollution while ensuring sufficient feeding.
