Problems solved by technology

[0004] Among them, the fabric analysis mirror method and the fabric decomposition method are all completed by manually counting the number of yarns. Due to the extremely fine yarns, serious false detections and missed detections often occur in manual detection, which seriously reduces the production efficiency in the fabric process.
The other is the weighing method, which weighs a certain area of ​​fabric on an electronic scale and roughly calculates the weft density value. Due to the large error of the calculated weft density value, it does not meet the needs. Although the operation is simple, it requires manual labor. Participation, unable to do online automatic measurement

Embodiment 1

[0027] In this example, see figure 1 and figure 2 , a hand-held portable fabric density detection system, mainly includes a sample carrying platform and a sample optical recognition system 2 arranged in the equipment box, the sample to be tested is fixedly arranged on the sample carrying platform, and an image acquisition system is arranged above the front of the sample carrying platform Port 6, the sample carrying platform is equipped with a sample installation port device, through which the sample to be tested can be fixed on the sample carrying platform. The sample to be tested includes the fabric to be tested and the reference test object. The sample optical recognition system 2 mainly It is composed of an image sensor 1, a micro optical lens 7 and an optical path compensation system 8. The micro optical lens 7 is arranged directly above the image collection port 6, and the image sensor 1 uses the micro optical lens 7 to pass through the image collection port 6 to collect...

Embodiment 2

[0044] This embodiment is basically the same as Embodiment 1, especially in that:

[0045] In this embodiment, the sample carrying platform can also perform horizontal rotation at a set angle, and the orientation of the sample to be tested can be adjusted as required. When the processor 3 controls the optical recognition system 2 to collect the image of the fabric sample to be tested, each acquisition After an image of the fabric sample to be tested, the sample carrying platform is rotated by a specific angle by driving the actuator to adjust the orientation of the sample to be tested, and then the image of the fabric sample to be tested is collected, and the orientation adjustment steps of the sample to be tested and the corresponding image acquisition are repeated Step three times, the processor 3 calculates the weft thread density of the fabric according to the rotation angle of the fabric sample to be tested and the image data of the fabric sample to be tested. In this emb...

Embodiment 3

[0047] This embodiment is basically the same as the previous embodiment, and the special features are:

[0048] In this example, see image 3 and Figure 4 , the sample optical recognition system 2 is manually focused to adjust the focus of the optical recognition system 2, using the black and white stripe test plate 9 as a reference test object for focusing, and fixing the reference test object to be tested on the sample carrying platform through the sample installation port device Above, after the user presses the focus button in the pair button panel 5, the sample optical recognition system 2 enters the focus mode after the pre-program of initializing the image sensor 1 runs, and uses the image sensor 1 to collect the image of the reference test object , and calculate the image contrast data, the processor 3 converts the image contrast data provided by the image sensor 1 into focus accuracy, provides an input and output device for display output, and prompts the tester to ...

Abstract

The invention discloses a handheld portable fabric density detection system, an image acquisition port is arranged above the front side of a sample bearing platform, a sample optical recognition system mainly comprises an image sensor, a micro optical lens and an optical path compensation system, the image sensor is used for acquisition of an image of a to-be-tested sample on the sample bearing platform via the image acquisition port by use of the micro optical lens, the optical path compensation system provides compensation light to a vision light field of the micro optical lens for acquisition of a clear image of the sample by use of the image sensor, the image sensor transfers acquired image data to a processor, the processor is used for image processing, analysis and calculation to obtain the appearance characterization information of the sample on the sample bearing platform. The handheld portable fabric density detection system combines digital image processing technology and an automatic control system combined to achieve accurate detection of static fabric density values, fabric images can be correctly calculated and analyzed, related parameters of fabric count can be obtained, and high speed detection and accurate measurement of woven yarn density can be realized.

Description

technical field [0001] The invention relates to a fabric detection system, in particular to a fabric optical detection system, which is applied in the technical field of textile quality detection and management. Background technique [0002] As the world's largest producer and exporter of textiles and clothing, my country's textile industry has always occupied an important position in the development of the national economy. Improving the quality of weaving is of great significance to the long-term development of the textile industry. The warp and weft density of the fabric is a very important reference index for the detection and control of the weaving quality. [0003] In general fabrics, the warp yarns are better if the yarns are parallel to each other, and the weft yarns are those with arcs or oblique lines. At present, in the domestic textile industry, the weft density detection of fabrics is mainly done manually by means of tools such as cloth mirrors or fabric densit...
