Embodiment
[0046] like Figure 1-3 As shown, the present embodiment provides a method for detecting unevenness of aircraft assembly fasteners, comprising the following steps:
[0047] Step S1: build a detection device, the detection device includes a scanner 110, the first camera 120 and the second camera 130 are respectively arranged on both sides of the scanner 110, the scanner 110 includes a line laser 111 and a one-dimensional vibrating mirror 112, the one-dimensional vibrating mirror 112 is used to reflect the linear laser light projected by the line laser 111 to the surface of the fastener under test;
[0048] Step S2: Output a synchronous square wave signal to the line laser 111 and the one-dimensional vibrating mirror 112 to change the rotation angle of the one-dimensional vibrating mirror 112, the one-dimensional vibrating mirror 112 rotates in a stepwise manner, and the line laser 111 lights up once for each rotation angle , so that the reflected light scans the surface of the...
