Abstract

The product quality in the iron and steel industry is highly important. From the casting process to bundling, a large amount of energy is used at each step of the production. In the present study, the counting of steel rebar bundles located in the storage area has been taken into account. When it is necessary to recount the rebar in a bundle, depending on the number of rebar in the bundle, either a staff is assigned to count or the bundle is moved for weighting again. Both of them are time and energy-consuming solutions. In the present study, an algorithm is developed to count the rebar in a bundle by taking a photograph of rebar tips. Although the existence of defects such as deforming cutting, steel rib features, lack of painting, and also insufficient lighting of the storage area, the proposed algorithm is able to give highly accurate results.

Hatalı Uçlu İnşaat Demirlerinin Yüksek Doğruluklu Sayımı

Abstract

Demir çelik sektöründe ürün kalitesi son derece önemlidir. Döküm sürecinden paketlemeye kadar, üretimin her aşamasında büyük miktarda enerji harcanılır. Bu çalışmada, depolama alanında bulunan çelik inşaat demiri sayımı dikkate alınmıştır. Bir paketteki demetin yeniden sayılması gerektiğinde, paketteki demet sayısına bağlı olarak ya saymak için bir personel atanır ya da tekrar tartılmak üzere götürülür. Her ikisi de zaman ve enerji tüketen çözümlerdir. Bu çalışmada, inşaat demiri uçlarının depolama alanlarında fotoğrafı çekilerek bir paket içerisindeki demet sayımı için bir algoritma geliştirilmiştir. Deforme kesme, çelik nervür özellikleri, boyama eksikliği ve ayrıca depolama alanının yetersiz aydınlatılması gibi kusurların varlığına rağmen, geliştirilmiş algortitma son derece doğru sonuçlar verebilmektedir.
