Embodiment Construction
[0033] The method for determining the sound field reconstruction plane in the acoustic camera system proposed by the present invention will be described in detail below with reference to the accompanying drawings.
[0034] The system that realizes the method of the present invention is as figure 1 Shown:
[0035] (1) Paste mark points on the side of the object to be measured, and divide the side of the moving object into two parts, the front and the back. The mark points attached to the front are as follows: figure 2 There are n type 1 marker points shown, and the marker points are evenly distributed, and the central square area of the type 1 marker point is intercepted as a template image. back attached as figure 2 There are m number of -1 type marker points shown. The marking points are evenly distributed, and the longitudinal spacing is not greater than 20% of the longitudinal size of the object. The selected world coordinate system is a right-handed coordinate syst...
