Method for achieving LOGO alignment based on 3D curved surface dynamic calibration of 2D vision

The invention discloses a method for achieving LOGO alignment through 3D curved surface dynamic calibration based on 2D vision, and relates to the field of computer vision recognition. The method comprises a calibration stage and an alignment stage, in the calibration process, a conversion formula for automatically calculating image coordinates and angles is achieved through heat preservation vessel or vacuum vessel pictures collected at equal angle intervals, in the alignment process, the angle needing to be rotated is calculated according to positioned LOGO positioning reference coordinates, and visual feedback alignment is achieved. A visual mode is adopted to replace a manual alignment mode, the full-automatic uninterrupted production requirement of an assembly line can be met in speed, the production efficiency is greatly improved, the stability of the marking precision of the heat preservation vessel or the vacuum vessel is improved, and the full-automatic marking process can be achieved. 本发明公开了一种基于2D视觉
