Abstract

The purpose of this research was to determine
the percent crop residue cover using  meter stick method, line transect method, image
processing software ImageJ and
Labview Vision Assistant Module in the field condition covered with wheat
surface residues and to compare results obtained from these measuring methods. In order to determine the percent
crop residue cover using ImageJ image processing software and Labview
Vision Assistant Module, photographs were taken with a digital camera of the
intelligent mobile phone from various places of a field covered with wheat surface
residues. At the end of study, the
mean percent crop residue cover using meter stick method, line transect method, image
processing software ImageJ and
Labview Vision Assistant Module were determined
as 44.13%, 50.72%, 56.56% and 64.49%, respectively. Variance analysis
showed that the difference between the results obtained from the line transect method and ImageJ is statistically insignificant while the differences between the
results obtained from these methods and the other methods are significant.

Bitki Yüzey Artığı Kaplama Yüzdesinin Belirlenmesinde Kullanılan Farklı Yöntemlerin Karşılaştırılması

Abstract

Bu
araştırmanın amacı; buğdayın yüzey artıklarıyla kaplı tarla koşulunda cetvel
yöntemi, kesişen hat yöntemi, ImageJ görüntü işleme programı ve Labview Vision Assistant Modülüyle yüzey artığı kaplama yüzdesinin belirlenmesi
ve elde edilen sonuçların karşılaştırılmasıdır. ImageJ görüntü işleme programı
ve Labview Vision Assistant Modülüyle yüzey artığı kaplama yüzdesinin belirlenmesi için, buğday yüzey
artıklarıyla kaplı bir tarlanın çeşitli yerlerinden akıllı cep telefonunun
dijital kamerasıyla fotoğraflar çekilmiştir. Araştırma sonunda; cetvel, kesişen
hat, ImageJ görüntü işleme programı ve Labview Vision Assistant Modülü
kullanılarak ortalama bitki yüzey
artığı kaplama yüzdeleri sırasıyla
% 44.13, % 50.72, % 56.56 ve % 64.49 olarak belirlenmiştir. Yapılan varyans analizi; kesişen hat
ve ImageJ görüntü işleme
yöntemlerinden bulunan sonuçlar arasındaki farklılığın istatistiksel olarak
önemsiz, bu yöntemlerle diğer yöntemlerden elde edilen sonuçlar arasındaki
farklılıkların ise önemli olduğunu göstermiştir.
