| Abstract: | Taking underwater topographical surveying as an example,the position and depth are consolidated in the space by fixing instruments and adjusting slant;the API clock of computer acts as the basis to right of the information orientation and the depth in the time axis.Then two types of information are formed into right three-dimension datas of space. |
