Problems solved by technology

However, when using laser measurement, it is necessary to scan, collect and process multiple images, which is time-consuming and difficult to achieve real-time measurement, and the measurement accuracy is easily affected by the diffuse reflection and inclination of the sample surface. There are also scanning blind spots

Abstract

A 3D non-contact coordinate measuring device of fabric consists of fabric holding unit set on horizontal desk surface and formed by actively connected rotary shaft and black magnetic plate, transducer formed by left camera and right camera as well as grating projector being all checked in slide groove and being able to regulate their positions. It is featured as attaching fabric to be measured on black magnetic plate, setting center of transducer to be the same height as that of fabric to be measured, connecting two said camera to microprocessor.

Description

technical field [0001] The invention relates to a three-dimensional non-contact measuring device for flexible objects, in particular to a three-dimensional non-contact coordinate measuring device for fabric or clothing material, which provides high-precision three-dimensional measurement data for digital textiles and clothing. Background technique [0002] In the anti-wrinkle finishing of textiles and the ironing of garments in garment factories, whether the flatness level of fabrics or garment fabrics meets the standard is an important indicator for evaluating their appearance. The existing evaluation methods are mainly based on the American AATCC-124 standard, and in a standard environment, it is carried out by professionals through the 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 methods are similar to the ...
