| Abstract: | Aiming at the difficulty in accurate plane positioning of underwater projects in large rivers,a study was performed on the application of plane measurement and positioning system to underwater projects.The combination of video technology with the short baseline acoustic positioning technology based on multi-array-elements base overcame the low precision of the conventional acoustic positioning.By adoption of the short baseline positioning method of multi-base elements for rapidly positioning,detecting,searching and determining the objects,and software for processing,recording,and displaying the result,an underwater plane positioning system which could meet the requirement of engineering precision was obtained,and the quality of underground projects was ensured. |
