Surface mounting plane coordinate thermal compensation method and system based on machine vision, and storage medium

The invention relates to the technical field of mounting error compensation, and particularly discloses a mounting plane coordinate thermal compensation method and system based on machine vision, and a storage medium, and the method comprises the following steps: determining four mark points on a mounting plane, and enabling a machine to recognize the coordinates of the mark points as reference coordinate points and recognize the position coordinates of mounting points; the current coordinates of the mark points are identified every preset time period in surface mounting production; according to the benchmark reference coordinate point and the current coordinate, respectively calculating the expansion and contraction proportions in the X-axis direction and the Y-axis direction under the coordinate system; and calculating the offset of the mounting point in the X-axis direction and the Y-axis direction according to the telescopic proportion and the position coordinate of the mounting point, and compensating th
