Problems solved by technology

For example, although the stretching lengths of the two fabrics are equal, their bending shapes are different, that is, there are great differences in the bending shapes of the fabrics during the stretching process, so the same stretching length does not mean that the fabrics have the same rigidity and flexibility.
The improvement of present stiffness-flexibility or stiffness testing instrument mainly includes: the infrared beam detection angle adjustable stiffness instrument introduced by patent document (CN87200553U), which can replace the visible slope of inclined-plane method test with infrared light; automatic fabric stiffness The tester (CN2421634Y) can realize the stable and effective lifting and falling of the sample pressing plate during the test, but their improvement is limited, that is, it can only surround the stretching length of the test fabric itself, and cannot express the bending form of the fabric. It is impossible to obtain the state change process of the fabric during the bending process, and the existing instruments can only be used for the test of the inclined plane method, and the test accuracy is poor, especially for soft fabrics that need to be tested by the heart-shaped method.
Within the scope of the inventor's search, there is no test instrument and related literature reports that use machine vision to obtain fabric rigidity and flexibility parameters

Description

technical field [0001] The present invention relates to a test instrument for fabric properties, specifically a test instrument for obtaining fabric rigidity and flexibility physical indicators such as fabric bending curve and extension length based on machine vision. The international patent classification number is intended to be Int.C1 G01N 1 / 00 ​​( 2006.01) Background technique [0002] The stiffness and flexibility of fabrics is an important indicator of fabric performance. The wearing performance of the fabric is closely related to the rigidity and flexibility of the fabric, and the material of the fabric and the structure, density and yarn fineness of the fabric will have an impact on the rigidity and flexibility of the fabric, so the rigidity and flexibility of the fabric can largely reflect performance of the fabric. The existing fabric rigidity and flexibility test index is mainly represented by the stretching length of the fabric when the angle between the line ...
