Abstract

The invention relates to the technical field of LCM preparation, and discloses an LCM frame packaging method and device based on image processing, and the method comprises the steps: obtaining an original image of an LCM based on a visual system, carrying out the preprocessing of the original image, carrying out the edge feature extraction, obtaining a preliminary edge image, carrying out the morphological processing of the preliminary edge image, and obtaining a final edge image; performing gray thresholding processing on the optimized edge image, calibrating a connected edge area in a plurality of specific areas, screening out a candidate point set according to geometric features of the connected edge area, screening the candidate point set, performing compensation correction on the initial dispensing path based on current position information of the LCM to obtain a corrected dispensing path, and outputting the corrected dispensing path. And the dispensing robot is controlled to carry out dispensing operation according to the corrected dispensing path, the problem of non-uniform glue caused by identification errors in the dispensing process can be effectively avoided, the initial dispensing path is compensated and corrected, the current position information of the LCM is dynamically adapted, and the accuracy and consistency of the dispensing path are remarkably improved.
