Embodiment Construction
[0051] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0052] like Figure 1-19 shown.
[0053] An image recognition method for friction stir welding arc groove spacing, the process is as follows figure 1 As shown, it includes the following steps:
[0054] (1) Acquisition of arc pattern images, including the following steps:
[0055] When image acquisition is performed on the arc pattern on the friction stir welding surface, the light source with a certain angle of incidence relative to the arc pattern surface is the only light source, and the image acquisition device such as figure 2 As shown, the incident light source effect diagram is as follows image 3 As shown, the angle between the incident angle and the horizontal plane should be less than 90 degrees, image 3 The incident angle is between 45 degrees and 60 degrees.
[0056] (2) Binarization of the arc pattern image, including the following s...
