SciSmart Applications——Grey Match

     Gray matching is a matching model based on gray information, and the similarity measure adopted is a normalized correlation function. The principle is to calculate the correlation coefficient values by a certain similarity measure pixel by pixel according to the gray matrix of a certain size real-time image window and the gray level array of the reference image. The larger the value is, the more similar the two are. The range of similar values is [0, 100]. However, the target should not overlap.

Application: Count the nut.

Software: SCI Smart Camera 2.4.1804.x.x and above.

Function：Count the number of the disorder products in figure.

Steps：

Figure2, Total procedure of the case

a) Step1：read image by “Image import”. replace the path of the images located, For example: D:/Demo Project/Match/Grey matching/Grey.

b) Step2：Locate the nut by “Grey match” Algorithm. Figure3 To meet the parameters of the gray-scale matching results (gray circle at the top right corner of the template, the image frame to match the target object).

Step3：Display the results by “Overlay”.
