Description

Technical Field

[0001] The utility model relates to the technical field of fabric surface area measuring devices, in particular to a fabric surface area measuring device based on visual recognition technology. Background Art

[0002] In the clothing industry, it is necessary to place the clothes on a measuring table after production and measure the dimensional accuracy and surface area by an inspector. The individual measurement data are recorded and can then be compared with the target values ​​predefined for the clothes. For example, as shown in the measurement system for measuring clothes with Chinese patent application number CN201980092755.X, at least one laser distance measuring device is provided, which emits a laser beam, wherein the laser distance measuring device is configured so that the laser beam passes through the table surface at a small distance so that when a piece of clothing is on the measuring table, the laser beam is irradiated on the clothing, at least one mark, the clothing is placed on the mark before being measured by the at least one laser distance measuring device, and a data processing device, which determines the length dimension of the clothing based on the values ​​measured by the one or more laser distance measuring devices.

[0003] However, when using the measurement system to measure the surface area of ​​clothing fabric placed on the measuring table, since the clothing fabric is only placed on the measuring table and cannot be pressed tightly, it is easy to cause inaccurate surface area measurement of the clothing fabric, and it is also impossible to measure both sides of the clothing on the measuring table. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, that is, simply placing the clothing fabric on the measuring table cannot compress the clothing fabric, which easily leads to inaccurate surface area measurement on the clothing fabric, and that it is impossible to measure both sides of the clothing on the measuring table, the present invention provides the following technical solutions:

[0005] A fabric surface area measuring device based on visual recognition technology includes a workbench, a clamping device for pressing and fixing clothes is provided above the workbench, a rotating device for flipping the clamping device is provided on the left side of the clamping device, and a measuring device for measuring the surface area of ​​clothes in the clamping device is provided above the workbench.

[0006] The clamping device comprises a placing component arranged above the workbench for placing clothes, and a pressing component for pressing the clothes is arranged on the top of the placing component.

[0007] The rotating device includes a support block for fixing the placement component, and a rotating component for driving the support block to flip is provided at the left end of the support block.

[0008] Furthermore, a support frame for fixing the measuring device is fixedly installed on the top of the workbench.

[0009] Furthermore, the placement component includes a placement table fixedly installed on the right end of the support block, and a placement groove for placing clothes is provided on the top of the placement table.

[0010] Furthermore, the pressing assembly includes a pressing plate inserted into the placement groove for pressing the clothes, and a bolt for fixing the placement table is provided on the top of the pressing plate, and the bolt passes through the plate body of the placement table.

[0011] Furthermore, the rotating assembly includes a rotating shaft fixedly mounted on the left end of the support block for rotation, a handwheel fixedly mounted on the left end of the rotating shaft for driving the support block to flip, and a fixing bolt for locking the handwheel is provided on the wheel body of the handwheel.

[0012] Furthermore, the measuring device includes a camera fixedly mounted on the top of the support frame for measuring the surface area of ​​the clothes placed in the assembly, and a display screen for displaying the camera measurement results is fixedly mounted on the left end of the support frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By setting a clamping device, a rotating device and a measuring device, when it is necessary to measure the surface area of ​​the clothing fabric, the clothing can be placed in the placement slot, and then the pressing plate is inserted into the placement slot and the clothing is pressed, and then four bolts are inserted into the four locking holes to lock the pressing plate. At the same time, the fixing bolts are loosened and removed from the handwheel, and then the handwheel is used to drive the rotating shaft to rotate, which can drive the clamping device at the right end of the support block to flip, and at the same time, double-sided measurement of the clothing can be achieved, and the camera automatically shoots the entire sample and outlines the outline of the clothing on the display screen. The number of all grids contained in the outer contour of the object can be converted into the area of ​​the plane. The front and back sides are photographed twice, and the display screen can calculate the corresponding surface area of ​​the number of grids contained in the special part on the plane. The host calculates the surface area of ​​the selected part and divides it by the overall surface area, so that the surface area ratio of different parts of the clothing can be calculated quickly and accurately.

[0030] The pressing assembly 210 includes a pressing plate 211 inserted into the placement groove 222 for pressing the clothes, and the cross section of the pressing plate 211 is convex, so that the pressing plate 211 can be inserted into the placement groove 222 to press and fix the clothes. At the same time, the pressing plate 211 is transparent, so that the measuring device 400 can be used to measure the clothes on the placement platform 221. The top of the pressing plate 211 is provided with a bolt 212 for fixing the placement platform 221, and the bolt 212 passes through the plate of the placement platform 221. The four bolts 212 are distributed in a rectangular array at the four corners of the top of the placement platform 221. When the surface area of ​​the clothes needs to be measured, the clothes can be placed in the placement groove 222, and then the pressing plate 211 is inserted into the placement groove 222 to press the clothes. Then, the four bolts 212 are inserted into the four locking holes to lock the pressing plate 211. This can prevent the clothes placed in the placement groove 222 from wrinkling, which may affect the measurement results of the measuring device 400.

[0031] The rotating device 300 includes a support block 320 for fixing the placement assembly 220 , and a rotating assembly 310 for driving the support block 320 to flip is provided at the left end of the support block 320 .

At the same time, the camera 420 can measure the surface area of ​​the clothes on the placement table 221, and the display screen 410 has a visual recognition technology system; and the camera 420 is projected onto the placement table 221, and when projecting a blank sample, it is projected as many fine lines. The sample is composed of small grids, similar to the pixel distribution effect of a display screen. The host calculates the surface area based on the size and number of the overall grid. The camera 420 automatically shoots the entire sample and outlines the outline of the clothing on the display screen 410. The number of all grids contained in the outer contour of the object can be converted into the area of ​​the plane. The front and back sides are photographed twice, and the display screen 410 can calculate the corresponding surface area of ​​the number of grids contained in a special part of the plane. The host calculates the surface area of ​​the selected part and divides it by the overall surface area, so as to quickly and accurately calculate the surface area ratio of different parts of the clothing.
