Multi-zone segmentation visual detection system and method based on embedded type framework

Abstract

The invention discloses a multi-zone segmentation visual detection system and method based on an embedded type framework. The system comprises a CPLD (complex programmable logic device) subsystem, an ARM (advanced RISC machines) subsystem, a DSP (digital signal processor) subsystem and an IO (integrated optics) subsystem, wherein the CPLD subsystem drives an image signal processor to collect original image data according to an external synchronous signal and a trigger signal, and simultaneously the CPLD subsystem performs video memory management and VGA (video graphics array) output management for a human-computer interface; the ARM subsystem controls the generation of user menus in the human-computer interface and responds to manual panel motions to complete settings of image collection working parameters and multi-zone segmentation parameters; and according to the working parameters and zones set by the ARM subsystem, the DSP subsystem respectively completes image processing in multiple zones which are segmented out to generate a determining result and output a pulse. The multi-zone segmentation visual detection system based on the embedded type framework and the detection method have the advantages of being capable of preventing a blue chip from affecting stain determination in detection, reducing false rate and improving the reliability of the detection. Simultaneously, the system integrates the human-computer interface, so that the problem of usability caused by the dependence on computers can be solved.

Description

technical field [0001] The invention relates to the technical field of image segmentation and image processing, in particular to a multi-region segmentation visual detection system and detection method based on an embedded framework. Background technique [0002] Non-woven raw materials are used in the manufacture of finished products of personal hygiene products such as baby diapers and women's sanitary napkins. They are disposable products and are in direct contact with the human body. Therefore, customers are extremely concerned about the quality and hygiene of the products. However, in the production process of finished products, it is inevitable that some dirt such as machine oil, powder, glue and even dead insects will adhere to the surface of the finished product, and the size of these dirt varies. At present, the production line speed of the domestic personal hygiene product industry is as high as 300m per minute. Manual random sampling inspection before packaging is...
