Visible foreign matter and bubble classification recognition detection method for medical (250ml)

Abstract

The invention discloses a visible foreign matter and bubble classification recognition detection method for medical large volume injection (250ml), and the method comprises the following steps: 1), continuously obtaining a plurality of images of large volume injection in detection; 2), carrying out the image pre-processing: filtering the images based on Top-Hat morphological filter; 3), carrying out image segmentation: carrying out the segmenting of the filtered images through employing an interframe differential method based on the maximum information entropy; 4), carrying out extraction of defected edges: extracting the edges of the visible foreign matters and bubbles through employing an SUSAN algorithm; 5), carrying out an image feature extraction algorithm: extracting the shape, gray and movement feature parameters for describing foreign matters and bubbles through the research and analysis of the features of defects; 6), carrying out the defect classification and recognition: achieving the recognition and classification of foreign matters and bubbles through employing an IDS-ELM algorithm. The invention achieves the recognition and classification of foreign matters and bubbles, can precisely classify and recognize various types of defects, and enables the products with different types of defects to be removed and placed in different defective product regions.

Description

technical field [0001] The invention belongs to the technical field of image processing and automation, and in particular relates to a method for classifying, identifying and detecting visible foreign objects and air bubbles in a 250ml large medical infusion solution. Background technique [0002] Glass bottles, plastic bottles, and plastic soft bags are the main materials for large infusions at home and abroad. At present, glass bottles are still the main container for large-scale infusion in China, and due to the lack of large-scale infusion production technology and packaging technology, it is often easy to mix hair, floating objects (plastic, fiber), glass shavings and other visible foreign objects with a diameter greater than 50um. Seriously affected the health and even life safety of the transfusion person. At present, the large infusion of glass bottles above 250ml in China mainly uses manual light inspection or imported equipment. Manual light inspection has the dis...
