Abstract

The invention discloses a three-dimensional non-contact coordinate measuring device for fabric or clothing fabric, which is composed of a fabric clamping device 1, a sensor 7 and a microcomputer 12 placed flat on a horizontal desktop 2, and the fabric clamping device 1 includes a movably connected rotating shaft 5 and a black magnetic plate 6, the fabric to be tested 3 is adsorbed on the black magnetic plate 6 through the magnetic strip 4; the sensor 7 is composed of a left camera 8, a right camera 8′ and a grating projector 9 that are stuck in the chute 10 and the position can be adjusted , the grating projector 9 is equipped with a white projection bulb and a coded grating that can produce regular variable frequency fringes; the center of the sensor 7 is at the same height as the center of the fabric 3 to be tested; the left camera 8 and the right camera 8' are connected to the microcomputer 12 The beneficial effects of the present invention are: quickly, accurately and efficiently capture the surface geometric information of the fabric, and provide rich and reliable three-dimensional measurement data for objectively evaluating the flatness level of the fabric.

Description

Technical field

[0001] The invention relates to a three-dimensional non-contact measurement device for flexible objects, in particular to a three-dimensional non-contact coordinate measurement device for fabrics or clothing fabrics, which provides high-precision three-dimensional measurement data for digital textiles and clothing. Background technique

[0002] In the anti-crease finishing of textiles and the ironing of garments in garment factories, whether the flatness grade of fabrics or garment fabrics meets the standard is an important indicator to evaluate its appearance. The existing evaluation methods are mainly based on the American AATCC-124 standard, and in a standard environment, the professional personnel conduct the comparison and comparison between the sample and the standard sample card. my country's national standard GB / T 13796-92 is formulated with reference to the American AATCC-124 standard, and the working environment and evaluation method are similar to the A...
