AI Technical Summary
Existing technologies struggle to effectively distinguish between mechanical wrinkles and electrolyte leakage in the sealing area of pouch lithium batteries, and are easily affected by the strong reflectivity of aluminum-plastic composite films, resulting in persistently high false alarm and false alarm rates in detection systems.
Multi-directional filters, such as Log-Gabor filters, are used for convolution processing to extract the energy amplitude of each pixel in different directions. The anisotropy consistency index and leakage diffusion disturbance flux are calculated, and the edge sealing quality is evaluated by nonlinear fusion in combination with the physical distance of the pixel relative to the edge sealing centerline.
It enables accurate identification and evaluation of the sealing quality of soft-pack lithium batteries, improving the accuracy and stability of detection and reducing false positives and false negatives.
