Study On Body Surveying System For Building

It is significative of studying the body surveying system, Based on summarizing and analyzing its development, problems and trend, establishing in extending and perfecting the existing theoretic and technic ,we carried out studying on the key aspect widely and profoundly. We studied on the data getting, data model and the distill method for body character .We also realized and ameliorated the system function. Finally, we gave some evaluate after some experimentations .The main contents of the paper are following:1. It is studied of the structure, characteristic, class and getting method; with the categories, the dimensional vector data model is put forward.2. It is discussed of the aspect and getting method for body character, the getting method for character based on surface fitting is especially studied.3. Some visualization method and idea for body character are summarized; it is useful for building visualization.4. The system composing and working elements are perfected, it is introduced of the system hardware, software, buildup and working. There are contents for setting of system function, data flow and design of database, etc.5. With the advanced program language of Delphi and the OpenGL technology, system design and system development are carried out, the main functions are implemented.6. Three stimulant tests are performed for the system applications, there are test schemes, data getting, data management, data disposing and data analyzing, the design functions are basically actualized .At last, it is pointed out of the disadvantage with the system.
