研究了利用免棱镜全站仪进行建筑物形态测量与分析的方法,重点研究了坐标系转换、非线性拟合、形态分析等关键问题。以校内标志物——混流式水轮机转轮为研究对象,利用免棱镜全站仪采集了该物体形态特征点的三维坐标,通过空间平面拟合完成了水轮机转轮的平整度计算与分析,通过坐标转换和平面拟合进一步完成了水轮机转轮圆心坐标、圆半径和圆度的计算与分析。研究和试验表明,利用免棱镜全站仪进行水轮机转轮的空间形态测量是一种快捷和精密的方法,该方法可为其他类似建筑物的空间形态测量提供一定的参考,空间形态测量的数据处理和方法也将得到更加深入的研究。
The method of using prismless total station to measure and analyze building shape is studied. The key problems such as coordinate system transformation, nonlinear fitting and shape analysis are studied emphatically. Taking the school-inside marker-Francis turbine runner as the research object, the three-dimensional coordinates of the morphological feature point of the object were acquired by prism-free total station. The flatness calculation and analysis of turbine runner was completed by space plane fitting. Coordinate transformation and plane fitting further completes the calculation and analysis of the circle center coordinates, circle radius and roundness of turbine runner. Research and experiments show that the use of prism-free total station instrument for the turbine wheel shape measurement is a fast and precise method, which can provide space for other similar shape measurement of the form of reference, the spatial shape measurement data Processing and methods will also be more in-depth study.
