Beschreibung
Zusammenfassung:	The invention relates to a maritime search and rescue method and system, and the method comprises the following steps: S1, receiving prediction request information of a distress target, building a drift prediction model according to the prediction request information, carrying out the calculation of a drift distance, and determining the position of the distress target according to the drift distance; and S2, determining an initial search area according to the position of the distress target by adopting a Graham scanning algorithm, determining a probability distribution diagram according to the initial search area, determining a target search area according to the probability distribution diagram, and performing search path planning. According to the maritime search and rescue method and system provided by the invention, the drift position of the distress target is determined by adopting the drift prediction model, and the final area of the distress target is determined based on the Graham scanning algorithm a
