Welding method for multiple working sites

The invention relates to a multi-working-site welding method. A reference point is arranged in a real welding area; the first camera obtains a background wide image of a real welding area, and adjustment and recording of adjustment parameters are carried out; defining an original point in the background width image, and establishing a plane coordinate system based on the original point and the adjusted background width image; inputting a to-be-welded material, obtaining a new width image, and adjusting based on the adjusting parameters; an estimated working site is obtained in the adjusted new wide image and corresponds to a real welding area, and a welding queue is constructed; and the welding equipment is started, a local site image is obtained in the real welding area, the welding position is determined, and multi-working-site welding is carried out. The precision is ensured to meet the requirement, and the labor cost is low; the method does not completely depend on input coordinates, makes up for image er
