The invention relates to a virtuality and reality combined distress rescue system and method. The system comprises a processing unit. The processing unit is configured to dispatch the unmanned underwater vehicle as a guide wing aircraft to the undersea to monitor undersea data, and construct a submarine topography virtual space based on the undersea data; under the condition that the manned underwater vehicle in distress is monitored, the position of an underwater target is determined based on cooperative positioning of a plurality of unmanned underwater vehicles, so that an evacuation route is planned; and controlling a plurality of unmanned underwater vehicles to guide the manned underwater vehicle in distress to go to a safe water area along the evacuation route in a mode of combining the unmanned underwater vehicles in water to form a three-dimensional guide sign. The plurality of unmanned underwater vehicles can perform refined detection on the submarine topography ground of the target water area to obtain the underwater landform situation, undercurrent distribution and other situations. The underwater global environment is monitored through the plurality of unmanned underwater vehicles, the blindness of follow-up rescue of the manned underwater vehicles in danger is avoided, and meanwhile, the navigation safety of the unmanned underwater vehicles and the manned underwater vehicles is improved.

本发明涉及一种虚实结合的遇险救援系统及方法，系统包括处理单元。处理单元被配置为：将无人潜航器作为引导僚机派遣至海下监测海下数据，并且基于海下数据构建海底地形虚拟空间；在监测到遇险载人潜航器的情况下，基于若干无人潜航器的协同定位确定水下目标的位置，从而规划撤离路线；控制若干无人潜航器以在水中组合形成立体引导标志的方式引导遇险载人潜航器沿撤离路线前往安全水域。本发明的若干无人潜航器能够对目标水域的海底地形地面进行精细化探测，获取水下地貌态势、暗流分布等情况。本发明通过若干无人潜航器进行水下全局环境的监测，避免了后续对遇险载人潜航器救援的盲目性，同时提高了无人潜航器以及载人潜航器的航行安全。
