Embodiment Construction
[0070] Combined with the case shown in Figure 1 and figure 2 The workflow shown in further illustrates the invention.
[0071] See Figure 1 and figure 2 , the case cited in the present invention is to use a non-contact structural dynamic response measurement system for wind tunnel tests to measure a four-story space rectangular frame fixed in a wind tunnel, and to realize three-dimensional structural dynamic displacement measurements on it to complete the wind tunnel test. The specific implementation steps of the structural dynamic response monitoring in the cave are as follows:
[0072] A. Build a wind tunnel test model and adjust the parameters of the high-speed camera.
[0073] A1. Fix the structure to be tested at a suitable position in the wind tunnel (1), determine the structural measurement points, and start the wind tunnel test non-contact dynamic response measurement system (7);
[0074] A2. Repeatedly adjust the spatial angles of the two high-speed cameras (3 an...
