The talks of digitalisation of apparel industry have been creating a buzz for quite some time now and the stakeholders are extending their support to digitalise those arduous supply chain processes which incur huge direct and indirect costs as well as take enormous time and a significant manpower. Garment measurement process is one such process which takes hundreds of man-hours to measure a huge number of garments in a factory on a daily basis, yet there is no certainty if the measurement is accurate and the passed garment won’t fail at receiver’s end!
The high chances of human errors linked with the traditional measurement process create mind-bending situation most often for the quality inspectors. However, now intelligent technology is available in the market that can solve these measurement problems.
AI-Driven Measurement Checking Machine by Yunji Zhihui, China
Located in Dongguan High-tech Development Zone in China, Dongguan Yunji Zhihui Technology Co., Ltd. is a high-tech industrial intelligent equipment developer and technical service provider. The company recently launched its high-tech garment visual inspection and measurement machine equipped with the vision system, which has filled the gap of the visual inspection system in China’s garment manufacturing industry where domestic intensive labour is located.
The garment visual inspection machine uses computer-vision inspection system as the core technology, artificial intelligence (AI) as the engine, and the integration of automated hardware mechanisms. The machine adopts assembly line design as reference. The tested T-shirts are laid on the machine belt/bed, and the parts that are not covered can be detected.
Once the garment product enters the machine, the screen, after 6 seconds, automatically shows the message – Pass/Fail, with all measurements. It can quickly and accurately detect the size of various parts of clothing, T-shirt in particular, and can automatically identify and calculate errors. The machine can also automatically identify product information and generate various quality reports required by the apparel factories.

For example, if a T-shirt passes through the machine, it automatically measures the 15 dimensions of the T-shirts in maximum 6 seconds which are – collar width, collar depth, left shoulder width, right shoulder width, left sleeve length, right sleeve length, left sleeve width, right sleeve width, chest width, waist width, T-shirt length, T-shirt width, sleeve length symmetry, shoulder width symmetry and cuff width symmetry.
The measurement capacity of the machine is 4,800 T-shirts in 480 minutes and it can adjust the speed if detection area increases.
This equipment is a complete set of clothing visual inspection solution, which greatly reduces labour costs and improves the automation level of clothing inspection. According to the company, the AI-driven equipment is suitable for large-scale clothing manufacturing enterprises.
While having a conversation with Apparel Resources, Sky Jia, General Manager of Yunji Zhihui, said that the machine is capable of checking products having multi-colour and multi-clothes. “The system automatically identifies the colour/fabric of the tested product and adjusts the test parameters accordingly,” commented Wang.
The machine has a high detection accuracy as the detection data error of the measured garment is controlled within ± 1mm, while manual measurement error goes as high as 5 mm. Also, the speed of the measurement is as low as 6 seconds per piece in the machine offered by Yunji Zhihui. “The measurement detection accuracy in our machine is up to 99.5 per cent with a large range of customisable measurement bed which can reach maximum at 900mm*900mm,” informed Jia.
Highlighting another key advantage of using this equipment, Jia said that the hardware capability and effectiveness is unbeatable. The product information can be obtained by intelligent identification barcode, QR code, RFID tag, etc. And, the factories are also able to print the unqualified information and mark the unqualified products automatically. Once marking of unqualified products happens, automatic sorting of qualified and unqualified products takes place.
As far as software capability of the machine is concerned, this includes three intelligent systems with powerful functions and changeable intelligence – an intelligent Al algorithm developed in-house; standard database management system which is in-built and flexible; and quality data analysis system for automatic analysis and summary of quality data as well as to generate relevant reports for production and quality data analysis.
The way forward for Yunji Zhihui Measurement Technology
The company’s R&D team is now extensively working to develop the function of defect detection which would be a breakthrough achievement. Also, the team is using its experience and technical know-how to replicate the same technology for other products than T-shirts as well.
Jia further shared, “As per a market survey done by us, we have developed the first product successfully used in clothing. I hope the product can serve more countries and more factories, but we haven’t sold overseas yet. We are also actively looking for overseas agents.”
