Automatic counting method and system for stacked goods

Abstract

The invention discloses an automatic counting method and system for stacked goods. The method comprises the steps that multiple pieces of video image data in the goods stacking and placing process are collected; performing image preprocessing on the video image data to obtain a preprocessed stacked cargo image; carrying out cargo box edge contour extraction and contour optimization fitting on the preprocessed stacked cargo image to obtain a stacked cargo area image; carrying out adhesion contour identification and adhesion contour segmentation on the stacked cargo area image to obtain a cargo box segmentation area image; according to the multiple cargo box segmentation area images, modeling is carried out on the cargos in the stacking and placing process, multiple three-dimensional models of stacking and placing of the different commodity cargos are obtained, and based on the three-dimensional models of stacking and placing of the different commodity cargos, a finally stacked and placed cargo pile three-dimensional model is generated; based on the three-dimensional model of the goods pile, the specific number or interval of the goods which are stacked and placed is obtained through counting; according to the invention, the accuracy and efficiency of counting the number of stacked goods are improved.
