Embodiment 1
[0032] A six-degree-of-freedom measurement method for large-space complex sites, see figure 1 , the method includes the following steps:
[0033] 101: Arrange multiple fixed reference points on the measurement space foundation, and measure the spatial coordinates of multiple reference points in the local coordinate system of each station at multiple different stations;
[0034] 102: The joint adjustment of datum point coordinates under multi-sites obtains the optimized datum point coordinates, establishes the datum point global coordinate system; arranges a measurement field composed of multiple transmitting stations on the top of the measurement space, and uses the datum point calibration method to solve the problem External orientation parameters of the measuring field;
[0035] 103: Measure the spatial coordinates of at least two photoelectric receivers on the six-degree-of-freedom measurement target in the global coordinate system and the real-time output of the inclinome...
Embodiment 2
[0044] The scheme in embodiment 1 is further introduced below in conjunction with specific calculation formulas and examples, see the following description for details:
[0045] The Indoor Spatial Measurement and Positioning System (wMPS) consists of a transmitting station, a photoelectric receiver, a signal processor and a terminal computer. The transmitting station is installed on the top truss of the measurement space, and emits two laser planes downward. The laser plane rotates with the rotating head of the transmitting station and scans the photoelectric receiver in the space. The synchronous light emits synchronous optical signals in a fixed period, and the photoelectric receiver receives After scanning the light and synchronous light, the results are transmitted to the host computer through signal processing, photoelectric conversion and other processing modules. The host computer obtains the scanning angle of the photoelectric receiver through time integration and combi...
Embodiment 3
[0072] The following combined with specific examples, Figure 2-Figure 3 The scheme in embodiment 1 and 2 is further introduced, see the following description for details:
[0073] In this method, by measuring the three-dimensional position coordinates of six photoelectric receivers distributed circumferentially on the six-degree-of-freedom target, combined with the angle information output by the inclinometer, the real-time simultaneous measurement of the six-degree-of-freedom target can be realized, specifically:
[0074] 1) Arrange multiple fixed reference points on the foundation of the measurement space ( figure 2 ), the point interval is 3-5m (the specific value is set according to the accuracy, measurement range, cost, etc. in the actual application), and the quantity should cover the measurement range. Through the three-dimensional measurement system with geodetic reference, such as: double theodolite system, laser tracker AT401 with leveling function, launch station...
