Problems solved by technology
However, the circle detection method based on Hough transform has the following disadvantages: first, it takes up a lot of memory and is not suitable for fast counting of straws on industrial production lines; Poor detection of irregular round objects
[0007] When these methods are counting the straws, the counting accuracy is not very high

The invention provides a straw counting method and device based on image processing and a storage medium. The method comprises the steps of obtaining an end face image which comprises the end faces of a plurality of straws to be counted, performing joint enhancement preprocessing on the end face image according to a scene image gray enhancement algorithm and a gray morphological enhancement algorithm to obtain a preprocessed image, extracting a closed edge contour of the straw in the preprocessed image according to a morphological hole filling algorithm, generating a sample set according to the closed edge contour, conducting morphological reconstruction according to the sample set, generating a weight template set, wherein the weight template set comprises a plurality of straw matching templates, and matching the straw matching template in the weight template set with the closed edge contour in the preprocessed image, and determining the number of the straws according to a matching result. The straw counting accuracy is improved.
Description
Technical field [0001] The present invention relates to a technical field of production straw, particularly, to a straw counting method, apparatus and storage medium based on image processing. Background technique [0002] Conventional straw package process, generally the number of counted manually using a pipette or counting weighing method. However, labor intensive manual counting, the counting efficiency is low; poor law count weighing accuracy. [0003] With the development of image processing technology, there are performed by the image processing count pipette, common image processing method comprising detecting block based on the counting method, detection method based on Hough circle (on Hough) transform based on least square circle and fitting counting method and the like. [0004] Detection count block-based approach is the cross-sectional image area of the suction pipe as a separate block, dividing the target through the corresponding enhancement and morphological op...
