The above-mentioned artificial intelligence control method for the textile fabric gray cloth winding machine is described in detail below with reference to specific embodiments.
The method comprises the following steps: and acquiring an image shot by a camera above the winding machine, and performing semantic segmentation to identify the fabric image.
This embodiment needs clear surface fabric surface image, according to surface fabric surface image characteristic, calculates the roughness of surface fabric, adjusts the extension power of rolling machine. All the surface images of the fabric on the winding machine need to be collected, and the characteristic information of the fabric surface in the images is identified.
In order to clearly display wrinkles on the surface of the fabric, a single-side LED lamp is used as a light source for illumination, light and shade changes can be formed at the wrinkles due to the existence of the wrinkles, the wrinkles are sharper, and the light and shade changes are more severe, so that the wrinkle characteristics of images can be described based on the phenomenon, and the wrinkles can be used for distinguishing the fabrics with different flatness.
The present embodiment adopts a DNN semantic segmentation manner to identify the target in the segmented image, and the relevant content of the DNN network is as follows:
a. the used data set is a fabric image data set on the winding machine acquired in a overlooking mode.
b. The pixels to be segmented are divided into 2 types, namely the labeling process of the training set corresponding to the labels is as follows: in the semantic label of the single channel, the label of the pixel at the corresponding position belonging to the background class is 0, and the label of the pixel belonging to the fabric is 1.
c. The task of the network is classification, so the loss function used is a cross entropy loss function.
Therefore, the processing of the fabric image on the winding machine is realized through the DNN, and the connected domain information of the fabric surface in the image is obtained.
Step two: and judging the flatness of the fabric according to the characteristic analysis of the fabric image.
And calculating a convex area and a concave area of each wrinkle according to the difference between the flat area and the wrinkle area of the surface of the fabric, analyzing the change characteristics of the gray value in each wrinkle area, and calculating the severity of each single wrinkle. And comprehensively obtaining the flatness of the current fabric.
The process for obtaining the fabric flatness in the embodiment comprises the following steps: a) The masked area in the folds of the fabric was calculated according to the Canny edge test.
b) And distinguishing a real wrinkle concave area according to the characteristics of the wrinkle concave area of the fabric.
c) And calculating the flatness of the fabric according to the gray level change of each wrinkle area.
The following are specific developments:
a) the masked area in the folds of the fabric was calculated according to the Canny edge test.
When the fabric is wrinkled, the gray level of the presented image is unstable. The gray values of the areas where the wrinkles are recessed are small, and the gray values of the areas where the wrinkles are protruding are large, as shown in fig. 2.
Therefore, the surface image of the fabric is subjected to graying treatment, then noise and miscellaneous points in the image are removed by using median filtering, and then convex areas and concave areas of folds are identified and segmented by using Canny edge detection, wherein the number of the convex areas and the number of the concave areas are respectively
Figure 711316DEST_PATH_IMAGE007
And
Figure 951804DEST_PATH_IMAGE020
calculating the area of each convex region of the fold, i.e.Obtaining a convex surface product set by the number of pixel points
Figure 371284DEST_PATH_IMAGE021
Then calculating the area of each fold concave area to obtain a concave area set
Figure 988210DEST_PATH_IMAGE022
. And finally, calculating gray values of all pixel points in the flat area on the fabric, summing the gray values, and taking the average value as R.
Due to the use of a single-sided light source for illumination, the convex area of the fold can generate shadows, which can be in the flat area of the fabric. When the segmentation is identified, the segmentation may be judged as a wrinkle concave area, which affects the calculation of the flatness of the fabric, so that the wrinkle concave area needs to be further analyzed.
b) And distinguishing a real wrinkle concave area according to the characteristics of the wrinkle concave area of the fabric.
When the flat area of the fabric is influenced by the shadow, the numerical difference of the gray value of each pixel point in the area is not obvious, and the gray value of each pixel point in the fold concave area gradually becomes smaller along with the downward depth of the concave pit. Therefore, the shaded flat area and the corrugated concave area can be analyzed according to the change of the gray value in the corrugated concave area.
Firstly, gray values of all pixel points in a fold concave area are calculated to obtain a set
Figure 809536DEST_PATH_IMAGE023
And n is the number of pixel points in the region. Recalculating sets
Figure 470193DEST_PATH_IMAGE024
Thereby obtaining a set of
Figure 376969DEST_PATH_IMAGE024
Standard deviation of (2)
Figure 266428DEST_PATH_IMAGE025
The calculation formula is as follows:
Figure 207839DEST_PATH_IMAGE026
wherein, aggregate
Figure 304977DEST_PATH_IMAGE024
Standard deviation of (2)
Figure 699049DEST_PATH_IMAGE025
The smaller the value of (b), the smaller the change in the gray level value in the description area, and the flatter the fabric.
Taking a plurality of flat areas on the current fabric, and calculating the standard deviation of each position
Figure 392199DEST_PATH_IMAGE025
Obtaining a set, and calculating the mean value of the set
Figure 922537DEST_PATH_IMAGE027
This is used as a threshold. When here the concave region is wrinkled
Figure 924997DEST_PATH_IMAGE025
Value less than
Figure 806365DEST_PATH_IMAGE027
Then, this region is a flat region. When the concave area is wrinkled
Figure 303206DEST_PATH_IMAGE025
Is greater than
Figure 219209DEST_PATH_IMAGE027
This region is a true recessed region. From this, the true fold concave area has
Figure 877724DEST_PATH_IMAGE008
A is prepared from
Figure 498585DEST_PATH_IMAGE028
. I.e. the area set of the fold valley regions is
Figure 533537DEST_PATH_IMAGE029
c) And calculating the flatness of the fabric according to the gray level change of each wrinkle area.
In conclusion, all the wrinkle convex areas and concave areas on the fabric are obtained, and the influence on the flatness is different due to different shape characteristics of the concave-convex areas. The effect of each fold on the overall flatness needs to be analyzed.
Firstly, a convex region is taken, the sum of the gray value of each pixel point in the region minus R is calculated, and a set is obtained
Figure 304047DEST_PATH_IMAGE030
Wherein
Figure 133463DEST_PATH_IMAGE007
The data in the set may represent the height of each point protrusion for the number of raised areas of the current fabric. Then a concave area is taken, the sum value of the gray value of each pixel point in the area after being subtracted by R is calculated, and a set is obtained
Figure 238691DEST_PATH_IMAGE031
In which
Figure 342913DEST_PATH_IMAGE008
The data in the set may represent the depth of each point depression, which is the number of concave regions on the current fabric.
So far, the overall concave-convex degree F of the current fabric can be obtained:
Figure 436771DEST_PATH_IMAGE001
the former term is the sum of products of the areas of the corrugated convex regions and the convex heights of the corrugated convex regions, the latter term is the sum of products of the areas of the corrugated concave regions and the concave depths of the corrugated concave regions, and the sum of the areas and the concave depths represents the overall concave-convex degree F of the current fabric.
And then calculating the sharpness of the whole wrinkle according to the height change of the convex area and the depth change of the concave area. The process of refining the wrinkle region, i.e. reducing the lines of the image from a multi-pixel width to a unit pixel width, is also called skeletonization. Thereby obtaining the peak ridge lines of the corrugated convex regions and the valley ridge lines of the concave regions.
Then analyzing the gray value change of the thinned ridge line, and firstly calculating a gray value set from one end to the other end of the ridge line of a fold area
Figure 92881DEST_PATH_IMAGE032
And m represents the length of the ridge line, namely the number of pixel points of the ridge line.
Then in the collection
Figure 419826DEST_PATH_IMAGE012
The former value is used to subtract the latter value to obtain the ridge fluctuation, which is summed up to take the mean value G. The degree of tortuosity of the ridge line is represented by G, and the calculation formula is as follows:
Figure 62160DEST_PATH_IMAGE009
wherein the content of the first and second substances,
Figure 541682DEST_PATH_IMAGE033
and the gray scale difference from one point to the next point on the ridge line is represented, m is the number of pixel points on the ridge line, and G is the average value of the gray scale difference on the ridge line and represents the tortuosity of the ridge line. The larger the value of G, the more tortuous the peak or valley-ridge lines of the wrinkles, and the greater the degree of wrinkles.
And if the ridge line is the corrugated convex area, taking the maximum gray value point on the ridge line. If the ridge line is the fold concave area, the minimum gray value point on the ridge line is taken. And a straight line perpendicular to the tangent line of the ridge line at the point is made in the fold area, and the straight line can represent slopes on the left and right sides of the highest part of the ridge line of the peak of the fold or the lowest part of the ridge line of the valley. Counting the gray value set from one end to the other end of the straight line

It is known that kurtosis is the degree of steepness of the distribution of the measurement data, and the distribution map is more steep when the kurtosis value is larger, and the distribution map is more squash when the kurtosis value is smaller. Thus can be assembled by calculation
