Contact feature library construction method, system, device and equipment and storage medium

The invention discloses a contact feature library construction method, system, device and equipment and a storage medium, and the method comprises the steps: carrying out the contact morphology collection of at least one relay sample, and obtaining at least one group of contact morphology images; extracting the contour and roughness information of a contact ablation area corresponding to each group of contact morphology images in the at least one group of contact morphology images; determining a plurality of characteristic parameters corresponding to each group of contact morphology images according to the contact ablation area contour and roughness information corresponding to each group of contact morphology images; wherein the characteristic parameters comprise one or more of an area parameter, a height parameter and a volume parameter; and establishing a contact feature library according to the at least one group of contact morphology images and the plurality of feature parameters corresponding to each group of contact morphology images. Thus, by establishing the contact feature library with the image features and the digital features, a data basis can be provided for relay failure mechanism judgment, and improvement of product reliability is facilitated.
