This paper presents a determine defect detection system, measurement
error or gather problem for the garment industry. The measurement of the completed suit and the followed evaluation of sewing quality and the correct joining of clothes is an important part in the industrial garment industry.
However, the main difficulty in using visual inspection to evaluate the finished garment quality is the time taken and labor wasted. In order to solve these problems, if we consider the structure of the dress, a three-dimensional measurement is required. The trouble with respect to vision-based system is the robustness of image processing algorithms. Safety and stability of finished goods are the key importance when dealing with an especially textile and automotive project. The stability of the finished products largely depends on their overall
geometry, and the results of the analysis depend on the certainty that this geometry can be measured practically. A three-dimensional laser scan will be required to determine whether a finished industrial product is manufactured within nominal scales. it helps to find different points of based on 3D-point measurement, and to allows determining the lines of connections point, straightness, flatness, roundness, cylindrical shape, symmetry, co-axiality, parallelism, perpendicularity, inclination, uncertainty and position in the structure.
This contribution gives a critical appraisal of the process used in the preliminary research phase: gathering the point clouds, 3D-modelling, structural analysis calculating from the normative design to the real design and the tolerance requirements that are obtained. The focus on the added value of the methodology is applicability of product specification, verification, cost-effectiveness, overall advantages and drawbacks.
