Embodiment Construction

[0049] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] like figure 1 and figure 2 As shown, a high-speed parallel visual detection method for visible foreign matter in a medical medicament of the present invention, its specific process is:

[0051] Step 1: Collecting images and preprocessing;

[0052] Step 2: Use the template matching method to locate the selected area and perform translation correction between frame sequences;

[0053] Step 3: Use the background difference method to extract the quasi-foreign object area, and use the method of morphology and image logic operation to construct anti-interference correction templates such as static bright area templates, differential highlight templates, and flashing area templates;

[0054] Step 4: Use the anti-interference correction template to align the foreign object area for correction;

[0055] Step 5: According to the fin...

Abstract

The invention discloses a high-speed parallel visual detection method for visible foreign objects in medical medicaments, which comprises the following steps: step 1: collecting images and preprocessing; step 2: using a template matching method to perform selected area positioning and perform translation correction between frame sequences; Step 3: Use the background difference method to extract the quasi-foreign object area; Step 4: Use the differential highlight template, static bright area template, and flash area template to correct the foreign object area; Step 5: Give the foreign object statistical information based on the final result image. The method constructs concurrent processing threads according to the frame number of sequence images, and the calculation process has high concurrency, which can give full play to the calculation performance of multi-core processors, and quickly and accurately identify visible foreign objects.

Description

technical field [0001] The invention belongs to the field of computer vision, in particular to a high-speed parallel visual detection method for visible foreign objects in medical medicaments. Background technique [0002] In my country, due to the problems of the production process and manufacturing technology level of transparent medicinal liquids made of glass packaging materials such as ampoules, infusion solutions, and oral liquids, glass chips, fibers, hair, white spots, white lumps, and colored liquids may appear in the medicinal liquids. Dots, color blocks, plastic chips and other insoluble visible foreign matter. If these medicinal solutions containing visible foreign matter are injected into the human body, vascular embolism and allergic reactions will occur, threatening the lives of patients. [0003] According to the description of my country's GMP: "Visible foreign matter refers to insoluble substances that exist in injections and can be observed visually under ...
