Image splicing method and system and electronic equipment

[0068] The embodiment of the present invention provides an image splicing method, which is applied to the weld detection of pipeline facilities, such as figure 1 As shown, the method includes:

[0069] Step S100, acquiring multiple original images to be spliced.

[0070] specific, figure 2 In the pipeline weld image acquisition device shown, the original image is acquired by the image acquisition device 230 installed on the trolley 220, and the image acquisition device 230 is composed of a CCD camera and a matching lens. Since the brightness difference on the surface of the pipeline is large, and the original image collected by the image acquisition device 230 will be distorted, the imaging effect of the welding area on the edge of the image will be poor, which will affect the subsequent splicing work. For the image in the middle position, the image with poor edge imaging quality is discarded.

[0071] According to the preset photographing position and photographing timing, t
