The artificial intelligent control method of 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.
The embodiment needs clear fabric surface images, and according to the fabric surface image characteristics, the flatness of the fabric is calculated, and the extension force of the winding machine is adjusted. 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 the wrinkles on the surface of the fabric, the single-side LED lamp is used as a light source for lighting, and due to the existence of the wrinkles, light and shade change can be formed at the wrinkles by light, the sharper the wrinkles are, the more intense the light and shade change is, so that the wrinkle characteristics of an image can be described based on the phenomenon, and the wrinkle characteristics 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: and in the single-channel semantic label, 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 role of the network is classification, so the loss function used is the 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 of obtaining the fabric flatness in this embodiment is as follows: a) The masked area in the folds of the fabric was calculated according to Canny edge detection.
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 Canny edge detection.
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 gray processing, 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 235234DEST_PATH_IMAGE008
And
Figure 207869DEST_PATH_IMAGE024
calculating the area of each fold convex area, namely the number of pixel points, and obtaining a convex surface area set
Figure DEST_PATH_IMAGE025
Then calculating the area of each fold concave area to obtain a concave area set
Figure 322587DEST_PATH_IMAGE026
. 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 wrinkle concave area can be analyzed according to the change of the gray value in the wrinkle concave area.
Firstly, gray values of all pixel points in a fold concave area are calculated to obtain a set
Figure DEST_PATH_IMAGE027
And n is the number of pixel points in the region. Recalculating sets

Figure 217281DEST_PATH_IMAGE032
Then, this region is a flat region. When here the concave region is wrinkled

Figure 359997DEST_PATH_IMAGE032
This region is a true recessed region. From this, the true fold concave area has
Figure 9284DEST_PATH_IMAGE009
A is prepared from
Figure DEST_PATH_IMAGE033
. I.e. the area of the fold concave region is integrated into
Figure 421942DEST_PATH_IMAGE034
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 DEST_PATH_IMAGE035
Wherein
Figure 373849DEST_PATH_IMAGE008
For the number of convex regions of the current fabric, the data in the set can represent the height of each point protrusion. Then a concave area is taken, the sum of the gray value of each pixel point in the area after being subtracted by R is calculated, and a set is obtained
Figure 629381DEST_PATH_IMAGE036
Wherein
Figure 551200DEST_PATH_IMAGE009
The data in the set may represent the depth of each point depression, which is the number of concave regions on the current fabric.
Thus, the overall concave-convex degree F of the current fabric can be obtained:
Figure 942999DEST_PATH_IMAGE002
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 degree 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 DEST_PATH_IMAGE037
And m represents the length of the ridge line, namely the number of pixel points of the ridge line.
Then in the collection
Figure 794368DEST_PATH_IMAGE014
The former value is used to subtract the latter value to obtain the ridge fluctuation, which is summed to take the average G. The degree of tortuosity of the ridge line is expressed by G, and the calculation formula is as follows:
Figure 271617DEST_PATH_IMAGE011
Wherein,
Figure 465969DEST_PATH_IMAGE038
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 meandering the peak ridge line or the valley ridge line of the wrinkle and the larger the degree of the wrinkle.
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, taking the minimum gray value point on the ridge line. 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 larger the kurtosis value is, the higher the distribution is, and the shorter the distribution is, the smaller the kurtosis value is. Thus can be assembled by calculation
