Abstract:

For dynamic path planning of unmanned aerial vehicle (UAV), we combine digital terrain, weather information, and other data to establish a full digital probability map.We then use a two level hierarchical planning method that includes ofine static planning and online real-time dynamic planning to realize dynamic path planning of UAV.The method is based on the sparse A* algorithm and cultural algorithm (CA).It solves the winding problem of sparse A* algorithm and improves reliability and real-time performance of tracking.

Key words: path planning, sparse A*algorithm, culture algorithm, probability map
