Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application. In addition, the technical features in each embodiment or single embodiment provided by the present application can be combined with each other to form a feasible technical solution, and this combination is not restricted by the order of steps and / or structure composition mode, but should be based on the implementation by those skilled in the art. When the combination of technical solutions appears contradictory or unfeasible, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection required by the present application.

[0023] The outdoor knitted fabric dye color number classification method provided by the embodiment of the present application is shown in the flowchart. Figure 1The method includes: emitting light within a preset wavelength range towards the dyed knitted fabric in a dark environment, collecting the reflected light and sending it to a filter; adjusting the filter array of the filter and adjusting the orientation of the filter to ensure that the light emitted from the filter outlet is directed to the imaging detector; when the imaging detector detects that the imaging brightness has reached the minimum value, locking the current filter at the filter inlet, determining that the light hue corresponding to the current filter band is the color of the dye applied to the knitted fabric; and classifying the color of the dye into an existing color code or classifying it into a new color code.

[0024] Based on the above method embodiments, as an optional embodiment, the outdoor knitwear dye color number classification method provided in this embodiment of the invention, wherein emitting light within a preset wavelength range toward the dyed knitwear fabric in a dark environment includes: emitting light within a preset wavelength range of 350 nm to 780 nm toward the dyed knitwear fabric in a dark environment. In another embodiment, the preset wavelength range can be 370 nm to 760 nm, 400 nm to 720 nm, or 420 nm to 700 nm.

[0025] Based on the above method embodiments, as an optional embodiment, the method for classifying dye numbers of outdoor knitwear provided in this embodiment of the invention includes adjusting the filter group of the filter, which involves rotating the filter group to sequentially rotate the filters in the filter group to the filter inlet; wherein the filter group is composed of a plurality of filters arranged in a ring, and each filter filters out light of a preset wavelength band within the preset wavelength range.

[0026] For details, please refer to [link / reference]. Figure 5 The filter assembly 501 consists of multiple filters (such as filter 503), each arranged in a closely spaced fan shape to form a ring structure. A central shaft 502 is mounted in the center of the disc surface of the filter assembly 501. The central shaft 502 is coaxial with a motor. When the motor is rotated under control, it drives the central shaft 502 to rotate, which in turn drives the filter assembly 501 to rotate. This allows each filter (such as filter 503) to be rotated sequentially to the filter entrance. The basic structure of the filter can be found in [reference needed]. Figure 6The outermost part of the filter is a cylindrical housing 601. A filter inlet 603 is located on the lower surface of housing 601, and a filter outlet 602 is located on the upper surface. The filter inlet 603 and the filter outlet 602 are aligned vertically to ensure that reflected light can smoothly enter and exit the filter. A central shaft 502 is installed in the middle of the filter assembly 501. The upper end of the central shaft 502 extends beyond the upper surface of housing 601, and the lower end of the central shaft 502 is connected to the middle of the lower surface of housing 601 by a pin. The central shaft 502 can rotate around the pin. When the central shaft 502 starts to rotate under motor control, it can open the filter (such as...) Figure 5 The filters (503) are rotated sequentially between the filter inlet 603 and the filter outlet 602, at which point reflected light can be filtered out. It should be noted that the number of filters on the filter group 501 can be determined according to the precision of the filtering band. When a higher precision is required, the number of filters is increased, and when a lower precision is required, the number of filters is decreased. Regardless of the number of filters, it is within the protection scope of this patent.

[0027] Based on the above method embodiments, as an optional embodiment, the outdoor knitwear dye color number classification method provided in this embodiment of the invention, wherein when the imaging detector detects that the imaging brightness has reached the minimum value, the current filter at the filter entrance is locked, includes: Where F is the imaging brightness on the imaging plate of the imaging detector; K is an intermediate variable; The light flux emitted from the filter outlet; The brightness of reflected light from knitted fabrics; is the imaging aperture diameter of the imaging detector; f is the lens focal length of the imaging detector; The amount of light received at the filter's entrance port; Pi; represents the light flux transmitted through the lens of the imaging detector; min is the symbol for the minimum value.

[0028] For details, please refer to [link / reference]. Figure 4 The imaging detector records the brightness of the image while transmitting it to the controller for transient storage (e.g., the controller's built-in RAM). The controller continues to control the rotation of the filter group in the filter. After rotating more than one full circle, the minimum brightness value can be obtained from the multiple imaging brightness values ​​stored in the controller by comparison. When the imaging detector detects the minimum brightness value again, it sends the minimum brightness value to the controller. The controller controls the filter group of the filter to stop rotating and locks the current filter at the filter entrance, determining the current filter band. Once the filter band is determined, the corresponding light wave color can be determined as the color of the dye applied to the knitted fabric.

[0029] It should be noted that after the knitted fabric is coated with the dye, the main reflected light wave is the same as the color of the dye, that is, the proportion of the wave band of the light wave of the same color as the dye in the reflected light is the majority (usually more than 90%), when the filter that filters out the light wave of the wave band filters out the reflected light, the remaining light is very little, and the filter of other wave bands cannot filter out the light wave of the wave band, that is, most of the light is emitted from the filter outlet, and when the imaging detector images all the emitted light of the filter, the imaging brightness of the light transmitted by the filter that filters out the light wave of the wave band is the smallest, at this time, the filter can be locked and the corresponding wave band can be determined, and the color corresponding to the light wave of the wave band is the color corresponding to the dye coated on the knitted fabric.

[0030] Based on the content of the above method embodiment, as an optional embodiment, the outdoor knitted fabric dye color number classification method provided in the embodiment of the application comprises: comparing the filter wave band of the current filter with the wave band corresponding to each color number in the existing color numbers, if the filter wave band of the current filter falls into the wave band corresponding to one of the color numbers in the existing color numbers, the color of the dye is classified into the one color number.

[0031] Based on the content of the above method embodiment, as an optional embodiment, the outdoor knitted fabric dye color number classification method provided in the embodiment of the application comprises: comparing the filter wave band of the current filter with the wave band corresponding to each color number in the existing color numbers, if the filter wave band of the current filter does not fall into the wave band corresponding to any color number in the existing color numbers, the color of the dye is constructed as a new color number, and the wave band corresponding to the new color number is the filter wave band of the current filter.

[0032] It should be noted that after the filter is locked, the light wave color tone of the filter wave band corresponding to the filter is compared with the light wave band corresponding to the existing color number, if it falls into the range of the wave band corresponding to one color number, it is determined that the dye color corresponding to the light wave color tone is the same as the color of the color number that falls into, and the dye color is classified into the color number; otherwise, if it does not fall into the range of the wave band corresponding to any existing color number after comparison, it is determined that the dye color is a new color number, that is, a new color number is established outside the existing color number categories, and the light wave band corresponding to the new color number is the filter wave band corresponding to the locked filter.

[0033] The method for classifying dye colors of outdoor knitwear provided in this invention involves collecting reflected light from the dyed fabric in a dark environment and sending it to a filter; adjusting the filter array and the orientation of the filter; and determining the color of the dye by the light wave corresponding to the current filter band at the filter entrance when the imaging detector detects that the imaging brightness has reached its minimum value. Finally, the dye colors are classified or distinguished, which avoids the need for manual classification and differentiation of color numbers, thus improving the efficiency and accuracy of dye color number classification and differentiation.
