Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to fig. 1 to 9 and the embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

The embodiment of the application discloses a clothing air permeability detection method. Referring to fig. 1, the clothing breathability detection method includes:

step 100: and (3) sleeving the garment on a dummy with an air injection system inside, sleeving detection test paper outside the garment, and blowing detection gas to the detection test paper through the garment to acquire the current detection area information.

As shown in fig. 2, the dummy is put on the garment, then the test paper is put on the outer side, the nozzles are densely distributed in the dummy, and then the air is blown outwards from the inner side of the garment to simulate the ventilation process, so that the blowing speed is slower and the garment and the test paper are not easy to blow up. And then placing test paper for detecting the concentration of the air drift outside the garment. In this embodiment, the test strip may be a wet litmus test strip, and then the test gas is carbon dioxide gas, and when the carbon dioxide gas blows out, the test strip is absorbed by the wet litmus test strip to make the litmus test strip appear red, and the test strip is blue or purple before the reaction.

The current detection area information is information of a detection area at any one same position. As shown in fig. 2, may be the abdominal region. The acquisition mode is to arbitrarily select one area or sequentially select the areas after all the areas are divided. The purpose of the acquisition is to select the region in a one-to-one manner, so as to determine the position of the region.

Step 101: and carrying out matching analysis according to the information of the induction paper area and the information of the current detection area stored in a preset induction database to determine the induction paper area corresponding to the information of the current detection area, and defining the induction paper area as the information of the current induction paper area.

The current sensing paper area information is the information of the area on the test paper corresponding to the current detection area information. The current sensing paper area information is substantially the area on the test paper through which the nozzle in the current detection area blows air. The database stores the mapping relation between the information of the sensing paper area and the information of the current detection area, and the mapping relation is obtained by observing the color change area on the test paper after the worker removes the clothing. When the system receives the current detection area information, the corresponding induction paper area is automatically searched from the database, and the current induction paper area information is output.

Step 102: and acquiring initial grid image information of the current induction paper area information.

The initial grid image information is the information of the grid-shaped image in which the nozzle does not start to jet air and the clothing and the test paper are installed, and in order to plan the area in the image and predict the color change area in the same image, criss-cross grids are planned on the outer surface of the test paper, and most of the grids are square in shape. The acquisition mode is shooting acquisition of the camera. The outer peripheral surface of the test paper is uniformly painted with grid images, and then the grid images are shot by a camera.

Step 103: and starting timing and acquiring current time information when the initial grid image information changes.

The current time information is information of a time point from the start of the change of the initial grid image information. The acquisition mode is timer acquisition, and the timing is started when any pixel in the initial grid image information changes in gray value. When the initial grid image information changes, it is indicated that gas has begun to pass through the garment to the test strip and react chemically with the strip. The thickness of the garment is relatively thin, and thus corresponds to the time for which the gas is blown out from the nozzle.

Step 104: and acquiring final grid image information when the current time information is equal to the preset detection time information.

The detection time information is information of a manually set duration. In order to prevent that some areas are saturated rapidly due to too high a concentration, while the rest is saturated for a long time although the gas permeation is small, a time is set so that the two are distinguished. In the embodiment of the application, the time may be the time when the clothing is removed, and then the air jet detection is directly started when the gray level on the image information changes from the beginning to the saturation non-changing position. The final mesh image information is image information when a time node from the start of the change to the detection time information is counted. The acquisition mode can be that a camera shoots and acquires.

Step 105: and analyzing the changed grid area information on the final grid image information according to the initial grid image information.

The changed mesh region information is information of a mesh region in final mesh image information different from the initial mesh image information. The analysis is performed by digitally comparing the gray values of the colors of each region in the initial grid image information and the final grid image information, and changing the grid region information when the numbers are different.

Step 106: and analyzing the change gray value information according to the change grid region information.

The change gray value information is the gray value of the grid corresponding to the change grid region information, and represents the content of absorbed carbon dioxide.

Step 107: and carrying out matching analysis according to the air permeability value information and the change gray value information stored in the preset degree database to determine an air permeability value corresponding to the change gray value information, and defining the air permeability value as detection air permeability value information.

The detected air permeability value information is information of a numerical value expressed by an air permeability number. The database stores the mapping relation between the air permeability value information and the change gray value information, the worker in the field determines the next air permeability value of the clothing with determined air permeability, then the clothing is put on a dummy for test to obtain gray values, and then the gray values are recorded in the database in a one-to-one correspondence mode. When the system receives the information of the change gray level, the corresponding air permeability value is automatically searched from the database so as to detect and output the information of the air permeability value.

Step 108: and carrying out matching analysis according to the detection standard information and the current detection area information stored in a preset standard database to determine a detection standard corresponding to the current detection area information, and defining the detection standard as current detection standard information.

The current detection standard information is information of a detection standard corresponding to each region, and is in a form of a table, namely, when the air permeability value is within a certain range, the corresponding air permeability level is. Here, different air permeability detection criteria are defined due to different areas of the garment. For example: the air permeability value may be lower in the chest area, but because the clothing itself is provided with a label at the position, the label is airtight, but other areas can be misjudged if the same standard is adopted if the air permeability is also adopted, so different detection standards need to be set up. The database stores the mapping relation between the detection standard information and the current detection area information, and the result obtained by the worker in the field according to the actual clothing condition and the test standard specification is recorded in the database. When the system receives the corresponding current detection area information, the corresponding detection standard is automatically searched from the database, and the corresponding detection standard information is output.

Step 109: and matching the detected air permeability value information with the current detection standard information to obtain detected air permeability information.

The detected air permeability information is information of the detected air permeability of the current detection area. The matching mode is to judge which numerical range of the detection standard the detected air permeability value information falls into, so that the corresponding mapping relation is found, and then the corresponding air permeability degree is output.

Step 110: and outputting the detected air permeability information.

Referring to fig. 3, the method further comprises a device detection method before air permeability detection, the method comprising:

step 200: and analyzing the single grid coordinate information and the corresponding single grid image information of each grid according to the initial grid image information.

The single grid coordinate information is information of coordinates of a selected grid in the initial grid image information, and includes edge line coordinates and center point coordinates, and can be information of grid coordinates obtained by establishing a coordinate system of a vertical plane by taking a certain position on a dummy as an origin. The single grid image information is the information of the image of the single grid of the detection test paper. The analysis mode can be that the position of the grid edge in the image is analyzed according to the image of the grid edge, and then the position is converted into corresponding single grid coordinate information and single grid image information according to the distance between the camera and the dummy.

Step 201: and analyzing the single boundary line image information from the single grid image information.

The single boundary line image information is information of boundary lines in the single mesh image information. The analysis may be by comparing color values between the two, which are edges when black.

Step 202: and carrying out matching analysis according to grid image information and single grid coordinate information stored in a preset image database to determine a grid image corresponding to the single grid coordinate information, and defining the grid image as theoretical grid image information.

The theoretical grid image information is information of theoretical images of single grids when all tools and objects to be detected are normal. The database stores grid image information and single grid coordinate information, and the whole image obtained by photographing by staff when all clothes, tools and the like are detected is obtained by dividing the whole image into single grid images and then matching and recording the single grid images and the single grid coordinate information. When the system receives the single grid coordinate information, the corresponding grid image is automatically searched from the database and is output according to the theoretical grid image information.

Step 203: and matching the single boundary line image information with the theoretical grid image information to obtain the coincidence degree information.

The overlap ratio information is information of the overlap ratio of the boundary line in the actual image and the boundary line in the theoretical image. The analysis is performed by placing the two images together and then determining the length of overlap of the two images.

Step 204: and judging whether the coincidence degree information is larger than preset coincidence threshold information.

The coincidence threshold information is information of a critical value of coincidence, for example, 95%.

Step 2041: if so, the test is started.

If the difference is larger than the preset value, the difference between the difference and the preset value is negligible, and the stone can be directly discharged for air permeability detection.

Step 2042: and if the output value is smaller than the preset value, outputting the fold information.

The fold information is information that the garment has been folded in this area. If the pressure is smaller than the preset pressure, the possibly raised area is indicated, the condition that the internal clothing is jacked up by the thickness increase of the internal clothing due to folding is indicated, and the detection test paper has certain tension and hardness, therefore, if the area is a recessed area, the test paper will not be recessed due to the situation of the test paper, so the overlap ratio is still high. It should be noted here that the case of the bulge in the structural design of the garment itself is excluded, and the case of the boundary line change due to the bulge of the garment itself is already included in the initial grid image.

Referring to fig. 4, the method further includes a method for processing the wrinkle information, the method including:

step 300: and carrying out matching analysis according to the nozzle number information and the single grid coordinate information stored in a preset nozzle database to determine a nozzle number corresponding to the single grid coordinate information, and defining the nozzle number as current nozzle number information.

The current nozzle number information is information of the number of the nozzle that can affect the cell grid coordinate information. Here a nozzle corresponds to a region where the grid is one nozzle for air exit. The database stores the mapping relation between the nozzle number information and the single grid coordinate information, and the mapping relation is obtained by testing by a worker in the field according to the actual position of the nozzle and the grid coordinate. When the system receives the single grid coordinate information, the corresponding nozzle number is automatically searched from the database, and the current nozzle number information is output.

Step 301: and analyzing according to the current nozzle number information and preset number rule information to determine upper adjacent nozzle number information and lower adjacent nozzle number information of the current nozzle number information, wherein the upper adjacent nozzle number information and the lower adjacent nozzle number information are adjacent to each other.

The numbering rule information is information of a numbering rule, for example, numbering is performed in such a manner that the numbering is sequentially increased by one digit from top to bottom and then sequentially increased by ten digits from left to right. The upper adjacent nozzle number information is information of the number of the nozzle located above and adjacent to the current nozzle number information. The next adjacent nozzle number information is information of the number of the nozzle located below and adjacent to the current nozzle number information. The analytical determination is performed by adding one and subtracting one directly to the number of units.

Step 302: according to the nozzle coordinate information stored in the preset position database, matching analysis is carried out on the current nozzle number information, the upper adjacent nozzle number information and the lower adjacent nozzle number information respectively to determine coordinates corresponding to the current nozzle number information, the upper adjacent nozzle number information and the lower adjacent nozzle number information, the coordinates corresponding to the current nozzle number information are defined as current nozzle coordinate information, the coordinates corresponding to the upper adjacent nozzle number information are defined as upper nozzle coordinate information, and the coordinates corresponding to the lower adjacent nozzle number information are defined as lower nozzle coordinate information.

The current nozzle coordinate information is information of the position of the nozzle corresponding to the current nozzle number information, here, information of the position on the vertical plane. The upper nozzle coordinate information is information of the position of the nozzle corresponding to the upper adjacent nozzle number information. The lower nozzle coordinate information is information of the position of the nozzle corresponding to the lower adjacent nozzle number information. The database stores the mapping relation between the nozzle coordinate information and the nozzle number, and the coordinate is input into the database for recording by the staff in the field when numbering. Only height information in the vertical direction and information of the lateral distance in the horizontal direction are contained here. When the system receives the current nozzle number information, the upper adjacent nozzle number information and the lower adjacent nozzle number information respectively, corresponding coordinates are automatically searched from the database and output as the current nozzle coordinate information, the upper nozzle coordinate information and the lower nozzle coordinate information respectively.

Step 303: and judging whether the current nozzle coordinate information is positioned above the single grid coordinate information.

The judgment mode is that the ordinate values in the coordinates are compared.

Step 3031: if yes, calculating a distance value between the current nozzle coordinate information and the single grid coordinate information, and defining the distance value as current blowing distance information.

The current blowing distance information is information of a distance from a position corresponding to the current nozzle coordinate information to a position corresponding to the single grid coordinate information. If so, it is indicated that the nozzle of the current nozzle number information is above the pleat.

Step 3032: if not, calculating a distance value between the upper nozzle coordinate information and the single grid coordinate information, and defining the distance value as upper blowing distance information.

The upward blowing distance information is information of a distance from a position corresponding to the upward nozzle coordinate information to a position corresponding to the cell grid coordinate information. If not, it is indicated that the nozzle of the current nozzle number information is below the pleat.

Step 304: and carrying out matching analysis according to the blowing wind power information stored in the preset strong wind database and the current blowing distance information to determine the blowing wind power corresponding to the current blowing distance information, and defining the blowing wind power as the current blowing wind power information.

The current blowing wind power information is information of wind power which can blow the folds corresponding to the single grid coordinate information when blowing according to the current blowing distance information. The database stores the mapping relation between the blowing wind power information and the current blowing distance information, and the mapping relation is obtained by recording the results of a large number of tests and theoretical value judgment by workers in the field. When the system receives the current blowing distance information, the corresponding blowing wind power is automatically searched from the database, and the current blowing wind power information is output.

Step 305: and calculating a distance value between the lower nozzle coordinate information and the single grid coordinate information, and defining the distance value as current spreading distance information.

The current spreading distance information is a distance value between the lower nozzle gauge stand information and the single grid coordinate information. The calculation is performed in such a way that the square root of each of the two abscissas is subtracted from each other.

The lower adjacent opening wind power information is information of wind power which is required to be sprayed out of a nozzle at the position of the lower nozzle coordinate information and used for separating clothing and test paper at the position corresponding to the single grid coordinate information. The database stores the mapping relation between the stretching wind force information and the current stretching distance information, and the worker in the field blows different wind forces out of the nozzles with the lower nozzle coordinate information under the conditions of different distances and different areas, then observes the distance between the detection test paper and the clothing, and records the wind force at the moment when the distance is increased and the distance is separated. When the system receives the current spreading distance information, the corresponding spreading wind power is searched from the database, and the following adjacent spreading wind power information is output.

When the coincidence degree information is larger than the coincidence threshold information, it is indicated that the wrinkles have been flattened at this time, so that the output of the wrinkle information can be canceled and the detection can be restarted. It is noted that here too, a time threshold length is provided, and if the time is reached, the fold information is still output.

Referring to fig. 5, the method of outputting wrinkle information when coincidence degree information after blowing is less than coincidence threshold information includes:

Step 401: and blowing the non-detection gas at a horizontal angle through the nozzles corresponding to the surrounding nozzle number group information according to preset separation wind force information to obtain separation boundary line image information.

The separation wind force information is the wind force information separating the test paper and the clothing, and the clothing and the gas can be separated due to the weight difference between the clothing and the gas when the air is blown around the separation wind force information. The purpose of blowing non-detection gas at a horizontal angle through the nozzles corresponding to the surrounding nozzle number group information according to preset separation wind force information is to separate detection test paper and keep a horizontal state so as not to be affected by clothes for observation. The image information of the boundary line is the information of the image of the boundary line after the test paper and the garment are separated.

Step 4041: if the output value is larger than the preset value, the fold information is output.

If a greater than situation occurs at this time, the description is actually a problem caused by clothing, and the output is wrinkle information.

Step 4042: if the paper abnormality information is smaller than the preset value, outputting the paper abnormality information.

The paper abnormality information is information for detecting that the paper itself is abnormal. If it is smaller than the predetermined value, it is indicated that the problem of the contact ratio abnormality still exists, and the problem may be a problem of the sheet boundary line, and the sheet abnormality information is outputted.

In this embodiment, in order to prevent the paper from falling, the paper is clamped by the clamping device above the paper, and at this time, when the nozzle is out to jet air, the detected paper swings. The calculation is performed by subtracting the ordinate values.

The mode of acquisition is a mode of manual input.

Step 503: and calculating equivalent clothing weight information according to the current clothing weight information, the paper swing radius information, the clothing fabric information and the clothing center information.

The equivalent clothing weight information is weight information obtained by equating the weight of the clothing itself to the paper swing radius information, and is essentially information of force required for blowing the current clothing weight information at the peripheral nozzle coordinate information. The method is that the current clothing weight information is multiplied by the attenuation proportion of clothing fabric information, then multiplied by clothing center information to form moment, and then divided by the paper swing radius information.

Step 504: and calculating equivalent test paper weight information according to the test paper center information, the test paper weight information and the paper swing radius information.

The equivalent test paper weight information is information that the weight of the test paper is equivalent to the weight obtained by the information of the swing radius of the paper, and is essentially information of force required for blowing the nozzle coordinate information around the test paper weight information.

The paper separation wind force information is information of wind force for blowing the weight corresponding to the equivalent paper weight information. The clothing separation wind power information is information of wind power which blows the weight corresponding to the equivalent clothing weight information. The database stores the mapping relation of the wind power and the weight of the clothes, and the wind power is recorded and recorded when the wind power is blown out from small to large to the clothes or the detection test paper starts to blow under the action of different weights by workers in the field. When the system receives the equivalent clothing weight information and the equivalent test paper weight information, the corresponding wind-off force is automatically searched from the database, and the wind-off force information and the paper wind-off force information are output respectively.

Step 506: and calculating the median between the clothing separation wind information and the paper separation wind information, and defining the median as separation wind information for output.

The median between the clothing separation wind force information and the paper separation wind force information is output, so that the paper can be blown without blowing the clothing, and the clothing and the detection test paper are separated. The purpose of selecting the median value is to integrate the two determinations and to be far from the boundary line, without causing a situation that is still not separated due to some deviation.

The calculation method is to define 0 DEG along the horizontal positive direction of the coordinate system, then analyze the angle of the vector formed by each point of the coordinate information of one change grid and the coordinate information of the change nozzle, and then analyze the maximum and minimum values, thereby determining the angle information of the change nozzle.

Step 604: and analyzing the change nozzle angle range information corresponding to the same change nozzle number information according to all the change nozzle angle information.

Here, because of the characteristics of the garment, the nozzles are provided along the circumferential direction thereof, so that when water permeates into the area corresponding to the information of the actual infiltration ordinate range, there is a circle of nozzles and their correspondence. The database stores the mapping relation between the nozzle number information and the actual infiltration longitudinal coordinate range information, and the mapping relation is obtained by a worker in the field according to the position of the nozzle and the number to determine the infiltration distance.

The nozzles corresponding to the number group information of the uniformly-smeared nozzles are used for blowing non-detection gas according to preset uniformly-smeared angle information, so that water drops gradually move downwards, are not attached to the detection test paper and are not adsorbed by the detection test paper because of the excessively low accumulated weight.

Step 707: stopping blowing and stopping dripping purified water when the degree of dripping of the water drops is detected to be the preset information of the dripping density of the water drops on the ground.

The information of the water drop density is the information of the drop density degree that the speed of gradually dropping water below the test paper is consistent after the pure water is gradually and evenly dropped above the test paper when the water drops are not adsorbed by the test paper at all. When the degree of water drop falling is detected to be the preset information of the water drop falling density on the ground, the litmus test paper is saturated, and blowing and dropping of purified water are stopped.
