Abstract

In this study, a circular Hough transform based image processing method has been developed to measure the dimensional changes of woven fabrics due to tensile force. For this purpose, needles were placed on woven fabrics with different structural parameters and the fabrics were pulled in warp direction. In the meantime, fabric images taken at intervals of 5 seconds for 30 seconds were recorded on the computer. The distances between the needles on the fabric images were measured both by hand drawing method and by image processing method developed using the circular Hough transform technique. When the results obtained from the two measurement methods were examined, it was seen that the deviation between the results was less than 1%. The average percentage deviation calculated by considering all measurements is only 0.26%. The correlation coefficient used to determine the strength of the relationship between the results obtained by the two measurement methods was calculated as 0.99. The developed image processing based measurement method can measure the dimensional changes of woven fabrics under stress easily, quickly and accurately.

Özet

Bu çalışmada çekme kuvveti sebebiyle dokuma kumaşlarda gerçekleşen boyut değişikliklerinin ölçülmesi amacıyla dairesel Hough dönüşümü tabanlı bir görüntü işleme yöntemi geliştirilmiştir. Bunun için farklı yapısal parametrelere sahip dokuma kumaşlar üzerine iğneler yerleştirilerek, kumaşlar çözgü doğrultusunda çekme işlemine tabi tutulmuştur. Bu esnada 30 saniye süresince 5’er saniye aralıklarla alınan kumaş görüntüleri bilgisayara kaydedilmiştir. Kumaş görüntüleri üzerindeki iğneler arası mesafeler hem el ile çizim yöntemiyle hem de dairesel Hough dönüşümü tekniği kullanılarak geliştirilen görüntü işleme yöntemiyle ölçülmüştür. İki ölçüm yöntemi ile elde edilen sonuçlar incelendiğinde sonuçlar arasındaki sapmanın %1’den düşük olduğu görülmüştür. Tüm ölçümler hesaba katılarak hesaplanan ortalama yüzde sapma değeri ise yalnızca %0,26’dır. İki ölçüm yöntemi ile elde edilen sonuçlar arasındaki korelasyon katsayısı değeri 0,99 hesaplanmıştır. Geliştirilen görüntü işleme temelli ölçüm yöntemi, dokuma kumaşların gerilme altındaki boyut değişikliklerini kolay, hızlı ve doğru olarak ölçebilmektedir.
