Three-dimensional positioning accurate identification method and system based on optimization algorithm

The invention discloses a three-dimensional positioning accurate identification method and system based on an optimization algorithm, and the method comprises the steps: carrying out the spatial clustering of an underwater target region according to the region information of the underwater target region of the ocean and the task information of a positioning task, obtaining a plurality of underwater target sub-regions, and setting an anchor node, according to the three-dimensional space coordinates of each anchor node, counting the minimum hop count from all unknown nodes to each anchor node by adopting a dual-communication radius mode; after the average hop distance of each unknown node is corrected according to the weight coefficient, the three-dimensional coordinates of each unknown node are determined by using an improved Pedal optimization algorithm; and after each unknown node is moved according to the three-dimensional coordinate of each unknown node, positioning identification is carried out on an obje
