Abstract

This invention relates to a method for detecting whether a battery is qualified, belonging to the field of battery safety inspection technology, and solves the problem of low efficiency in existing battery safety inspections. The method includes: accumulating the grayscale values ​​of pixels corresponding to each horizontal coordinate pixel number in the two-dimensional feature image to be inspected across all vertical coordinate pixel numbers to determine the horizontal coordinate pixel numbers corresponding to all electrodes in the battery to be inspected; extracting line features from the two-dimensional feature image to be inspected, dividing all straight line segments to all electrodes based on the electrode thickness and the horizontal coordinate pixel numbers corresponding to all electrodes, determining the pixel number corresponding to each electrode, determining the difference in vertical coordinate pixel numbers between adjacent cathode and anode electrodes, and combining this with the height of each pixel to obtain the OverHang of the battery to be inspected; comparing the OverHang of the battery to be inspected with the OverHang of a standard battery to determine whether the battery to be inspected is qualified. This achieves rapid detection of battery qualification.
