Embodiment Construction

[0041] refer to figure 1 , a method for detecting the number of tablets in a regular grid proposed by the present invention, comprising:

[0042] Step S1, obtaining the original image of the dispenser grid;

[0043] In a specific scheme, the original images of the grids of the dispenser are collected by the camera, and these original images of the grids of the dispenser are the basis for detecting the number of tablets.

[0044] Step S2, transforming the original image of the dispenser grid into a binary image of the dispenser grid, and detecting the binary image of the dispenser grid through a corner point detection and screening method to obtain a rectangular binary image.

[0045] In this step, the original image of the drug device grid is converted into a drug device grid binary image, which specifically includes: converting the original image of the drug device grid into a drug device grid grayscale image; Gaussian denoising was performed on the grid grayscale image; th...

Abstract

The invention discloses a method for detecting the number of tablets in a regular grid. The method comprises the following steps of: obtaining an original image of a grid of a doser; converting the original image of the grid of the doser into a binary image of the grid of the doser, and using the corner detection and screening method to detect the binary image of the grid of the doser to obtain arectangular binary image; detecting the contour on the rectangular binary image to obtain a contour binary image of the tablets; using a classified noise elimination method to eliminate noise in the contour binary image of the tablets to obtain a denoised tablet contour binary image; determining whether the tablet contour fits in the denoised tablet contour binary image, if no, using a contour detection method to detect the denoised tablet contour binary image to obtain the number of the tablets; and if yes, using a convex defect method to identify the denoised tablet contour binary image to obtain the number of the tablets.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for detecting the number of tablets in a regular grid. Background technique [0002] With the development of society, the drug delivery tools used by doctors in hospitals are becoming more and more advanced. Nowadays, it is only necessary for the doctor to put the corresponding number of pills into the regular squares of the drug dispenser, and the hospital’s automatic packaging machine will help you pack the pills one by one, which provides great convenience for the doctor and reduces the cost of medical treatment. Less chance of mispackaging. [0003] However, in a hospital, it is often the same doctor who places the pills, often for many hours at a time. In the process of repeating monotonous activities for such a long time, it is inevitable to encounter operational errors. However, in a place like a hospital, a small misstep could very well affect a patie...
