Abstract: A water-air integrated search and rescue system includes a flight power module, a navigation power module, a plurality of biomimetic unmanned boats, a drone, and an integrated control module. The integrated control module is configured to acquire weather information and determine whether to send a flight signal to the flight power module or to send a navigation signal to the navigation power module based on the weather information; the flight power module is configured to fly the drone to a search and rescue region after receiving the flight signal; the navigation power module is configured to navigate the drone to the search and rescue region after receiving the navigation signal; the integrated control module is further configured to control the drone to deploy the plurality of biomimetic unmanned boats; and the plurality of biomimetic unmanned boats are configured to carry out search and rescue work in the search and rescue region.

Abstract: A method for semantic perception editing of objects in a three-dimensional scene includes steps as follows: input point cloud data of a three-dimensional scene is analyzed by using a three-dimensional instance segmentation network, and a current position and a bounding box of a target object are determined based on an editing instruction. A set of semantic relationship rules between the multiple object instances from a historical editing case database is learned by using a Bayesian dynamic updating mechanism, and dynamic semantic constraints are dynamically generated. Editing operations are converted into a standardized mathematical representation by using a unified parametric framework, and the verified editing operations are optimized based on a comprehensive loss minimizing function to obtain optimized editing parameters. The three-dimensional scene is transformed based on the optimized editing parameters to obtain the edited three-dimensional scene.
