Expert System for 3D Collar Intelligent Design

A method to set up 3D collar prototype is developed in this paper by using the technique of cubic spline and bicubic surface patch. Then the relationship between the parameters of 3D collar prototype and different collar styles are studied.

关于布疵检测计算机处理系统的研究工作,国内还刚开始。本文首先介绍了国外三种检测方案,并就如何提高检测灵敏度、提高识别能力等向题,从制造角度和理论角度提出了一些注意点和应该考虑的问题。本文重点分析了计算机数据处理的检疵原理,实质上是一个判别一组数据信息中是否包含有周期性信息的问题。文章具体分析了两种判别方法,一种是自相关分析方法,它是利用波形的相似性,从几个波形的“混合物”中(线性迭加波形)提取有用的波形即疵点信息;另一种是富里叶变换分析,从频谱上来判别疵点信息。最后还提出了有待进一步研究的课题。     

Improved Genetic Algorithm Application in Textile Defect Detection

Based on an efficient improved genetic algorithm, a pattern recognition approach is represented for textile defects inspection. An image process is developed to automatically detect the drawbacks on textile caused by three circumstances： break, dual, and jump of yams. By statistic method, some texture feature values of the image with defects points can be achieved. Therefore, the textile defects are classified properly. The advanced process of the defect image is done. Image segmentation is realized by an improved genetic algorithm to detect the defects. This method can be used to automatically classify and detect textile defects. According to different users＇ requirements, different types of textile material can be detected.     

Imitation of Fabric Flagging Based on Amplitude Modulation

A model-independent 3 - D texture synthesis ofphysical and stochastic algorithms, based on an amplitudemodulation method, is presented to realize 3 - D fabricdynamic simulation. The physical functions are built tosimulate fabric basic deformation. The stochasticfunctions, generated by Perlin noise, are used to simulatefabric natural motion in the wind. The two kinds offunctions are synthesized by method of amplitudemodulation. As the arithmetic uses stochastic functions instead of recursive algorithm, it is capable of simulating thefabric material, the wind force and direction in real-time.Given the fabric material and wind strength, thestochastic functions can be created to simulate fabricmotion in the wind and this model can be adjusted bycontrolling some certain parameters to achieve a goodsimulation effect. This method is conceptually intuitive,computationally fast and efficient. Furthermore, thecombination of fabric physical and statistic motioncharacteristics provides an attractive way to improve thedisplay effect and rate.
