Technical progress and analysis on largescale spatial angle measurement

  • With the rapid development of large equipment manufacturing industry, the manufacture and assembly processes have increasingly higher demands on largescale spatial geometric quantity measurement. In order to analyze the development of angle measurement technology in largescale spatial geometric quantity measurement, 5 traditional methods were reviewed, and 3 new related research achievements about angle measurements were introduced. Then combining the optical selfcollimation tracking technology and inertial measurement technology, a novel largescale spatial angle measurement method based on inertial reference was elaborated. The method can perform portability, versatility and strong antiinterference ability and it is very suitable for field measurement. Test results show that the current measurement range is 10 m and the measurement accuracy is 0.5 .Additional the improving schemes for the measurement range and accuracy were put forward.
