| Based on the body surveying systems which had been made, the body surveying system for huge building is exploited with the new function of total station in reflectorless. The study and development of body surveying system in inner and outer country is analyzed and absorbed, the data analyzing system in the body surveying has been designed with the characteristics of body surveying in huge building, besides ,the influence factors to the precision of reflectorless, the management of body data , data visualization and the display of three-dimension figure are studied deeply. The main contents of the paper are following:1 .According to the new reflectorless technology of total station, the precision of reflectorless is analyzed in theory, the environment factors to produce errors are studied, and the special test is designed, so an all-around analysis is done.2.Today, the corresponding checking methods have not been regulated in measure unit checking regulation in our country, the checking department carry out checking with existing checking regulation, so the apparatus checking has not been carried out .the capability of reflectorless is tested, which can offer the reference to setting down the checking regulation. At the same time, analyzing the test data carefully, holding the capability of reflectorless practically, and analyzing the precision and influence factors are necessary to guide the practice application with conclusions gained.3.The system configuration and constitution of body surveying system is studied. The key problems of system direction and coordinate conversion which should be resolved in the work flow are analyzed. According to the practice characteristics of body surveying in huge building, directional calculating the unite adjustment ways are put forward, which can work out the influence of direction again with artificial factors, and have more advantages than former ways.4.According to the body surveying in large construction, the body configuration of the "data processing system in body surveying system" is analyzed and designed. The abundant data analyzing functions are offered. Object oriented procedure exploiting technology makes the data processing of body surveying, data management and message analyzing realized the automatization and visualization.5.In the data visualization, using the visualization modules and strong plotting technology which OpenGL has , the all-around data processing system is exploited , the display of three-dimension figures comes true, and the three-dimension figures become more verisimilitude because of the texture processing. |
