Abstract£º Underwater enviromental modeling and observation can be realized through Autonomous Underwater vehicle (AUV). The effects of AUV roll and pitch swing on the sonar image have been analyzed in order to make research on the mechanism of skewness correction. Local map has been sampled and obtained through partical filter of image sonar. Local map has been analyzed and combined through updating family tree and overall topo map on the basis of image sonar. Simmulation and tank experiments have verified this research.
Keywords£º Underwater Vehicle; Local map sampling; Map combination; Particle tree
