Our customer is one of the French market leaders in the field of orthopedic textiles. The control of the industrial knit fabrics is essential to ensure the quality of the final product. However, when performed by an operator, such quality control tasks suffer from several drawbacks:
ADDI-DATA faced several technical challenges to to meet these customer requirements, especially to ensure the reproducibility of the process regardless the position, the orientation and the folds of the knit fabric. To speed up the quality control process, the solution needs to be integrated into the running process and carry out the measurement of a knit fabric in a few seconds.
A neural network has been trained to automatically determine the measurement points for each knit fabric reference.
ADDI-DATA has developed a method for geodetic distance measurement along the knit fabric surface. This method is based on the use of multiple 3D cameras, to avoid missing data in the points cloud.
ADDI-DATA designed a solution that meets the different needs, according to the following process:
The complete machine vision system for the automation of dimensional measurements of knit fabrics designed by ADDI-DATA consists of:
