2. Multi-surface target detection and tracking method based on multi-robot system

2. Research on application algorithms of surface lasers

Current research results:
A lightweight neural network is used to classify riverside targets, and particle filtering and convex polygons are used to extract the drivable area of the target water surface.

Future research directions:
1. Use laser radar to realize 3Dslam positioning, solve the impact of high dynamic water surface SLAM technology, and realize autonomous positioning of unmanned ships under weak GPS conditions.
2. Use lidar to realize accurate perception of water surface objects. Aiming at the characteristics of large swings and large appearance differences of water surface objects, use lidar or fusion with other sensors to accurately realize 3D modeling, positioning and tracking of water surface objects.

3. Robot motion planning and control technology

Mainly focus on the planning and control technology of unmanned vehicles. The three main directions currently under research are motion planning technology considering uncertainty, data-driven planning methods, and end-to-end steering control methods. Among them, the research direction of uncertain motion planning technology welcomes those who have a mathematical background or are interested in optimization control to contact me.

The direction of control technology mainly focuses on path tracking control based on reinforcement learning and adaptive tracking control methods.
