In order to solve the problem of mine detection at surf zone, a streak?tube imaging blue?green lidar on unmanned aerial vehicle can be used for scan, detection and identification of mine. Blue?green lidar imaging is steady day and night. The detection efficiency of STIL can be enhanced relative to traditional detection mode of underwater, surface, etc. The UAV?borne STIL can be carried on muiliple platforms such as small ships, minicars, etc.
