A Spatial Point Location Measurement Method Based on Space Analytic Geometry
In the practice of engineering measurement,it is often encountered that the point positions of spatial points on certain engineering entities(buildings,bridges,transmission lines,etc.)need to be determined.Given that the spatial points must be on a certain plane or regular surface of the engineering entity,a spatial point measurement method based on space analytic geometry is proposed to obtain the three-dimensional coordinates of spatial points.Taking the spatial point location measurement on transmission line as an example,the basic principle of this measurement method,observation scheme,correlation of observation quantity with the spatial geometric elements of engi-neering entity,and derivation of relevant mathematical calculation model are discussed.The experi-mental comparative measurements on simulated overhanging transmission lines are carried out,and the measurement results verify the effectiveness of the spatial point location measurement method based on space analytic geometry.
