Method and device for calculating coating value of laminated cell, and storage medium

The invention discloses a laminated cell coating value calculation method and device and a storage medium, and the method comprises the steps: a to-be-detected laminated cell is determined, an anode membrane in the laminated cell sequentially comprises an ABCD endpoint, and a cathode membrane in the laminated cell sequentially comprises an EFGH endpoint; obtaining a first diagonal included angle of the anode diaphragm and a second diagonal included angle of the cathode diaphragm; a first projection image is obtained through the projection device, and the first projection image comprises projection points of the A end point, the C end point, the E end point and the G end point; after the laminated cell is rotated for the first time, a second projection image is obtained through the projection device, and the second projection image comprises projection points of the B end point, the D end point, the F end point and the H end point; and according to the first diagonal included angle, the second diagonal include
