Example Embodiment
[0044] The specific embodiments of the present invention are described in detail below with reference to the technical solutions and the accompanying drawings.
[0045] In this embodiment, four laser trackers of the AT960 model produced by Leica Company are selected, with a measurement range of 60m and a measurement uncertainty of ±15μm+6μm / m; four 1.5-inch target balls are selected as the common points to be measured. In the experiment, the positional relationship of the four target balls arranged satisfies P 1 with P 2 The spacing is about 5m, P 3 and P 1 , P 2 The spacing is about 4.7m, P 4 with P 1 , P 2 The spacing is about 4.4m, and P 3 The spacing is about 3.6m. In this experiment, four laser trackers measured four common points of four target balls at four stations respectively, namely m=n=4, and the measurement field size was about 7×6m.
[0046] The present invention first reasonably arranges four non-coplanar target balls to the common point P of No. 1, No....
