Marine ranch fishery resource quantity statistical method based on image recognition technology

The invention relates to the technical field of marine ranch fishery resource quantity statistics, in particular to a marine ranch fishery resource quantity statistics method based on an image recognition technology. According to the method, water depth topographic measurement is carried out through multiple beams, an underwater three-dimensional topographic model is constructed, and the fish reef putting amount is calculated according to the underwater three-dimensional topographic model and a multi-beam topographic measurement water depth map; then selecting a demonstration area edge and an artificial fish reef, counting the marine ranch fishery resource quantity of a unit reef body by adopting an image recognition technology, and completing the marine ranch fishery resource quantity statistics based on the image recognition technology; according to the invention, a method for measuring and evaluating changes of marine ranch fishery resources by using an image recognition technology is exploratively tried,
