Abstract: Through computer technology, automation technology and modern surveying and mapping technology, an underwater landform surveying vessel system was studied and developed by integrating unmanned vessel, GPS, echo sounder, obstacle avoidance radar, wireless communication equipment, computer, electronic compass, power system and other equipment. The system has functions of automatically avoiding fish net and obstacles, oil-electric hybrid drive etc., which is adapted to underwater landform survey of shoal, reservoir, lake, pool and other difficult underwater survey areas. The practical application shows that, compared with the traditional manned one, the unmanned vessel survey has the advantages of high efficiency, high accuracy in some specific difficult areas. The unmanned vessel survey, as a new measurement technique and method, will has a broad application prospect in the future.
