摘要
The paper deals with the measurement of the conical shape of lower ceiling by the total station Leica TCR307 and with the evaluation for its reconstruction. The 3D coordinates of the upper and lower border of the conical surface are calculated. The center of the circle and the deviations of measured borders from the average circle inserted in the separate parts of the lower ceiling are determined. The conical surface of the lower ceiling was unrolled in the plane for the correct determination of the size of new facing.
