Summary
Bu çalışmada görüntü işleme yöntemleri kullanılarak bitki taç izdüşüm alanının hızlı bir şekilde hesaplanması amaçlanmıştır. Denemeler için brokoli (Brassica oleraceae L.) bitkilerinden elde edilmiş fotoğraflar kullanılmıştır. MATLAB yazılımı kullanılarak oluşturulan program ile bitkiler renk uzayındaki farklarından yararlanılarak zeminden ayrılmıştır. Ölçüsü bilinen çerçeve alanı ile oranlanarak bitkinin gerçek alanı hesaplanmıştır. Aynı fotoğraflarda alanlar, planimetre ile de hesaplanarak süre ve doğruluk bakımından karşılaştırılmıştır. Görüntü işleme ile hesaplanan alanlarla planimetreyle ölçülen alanlar arasında R2=0.983 olan doğrusal bir ilişki bulunmuştur. Görüntü işleme ile alan 0.002 saniyede hesaplanırken planimetreyle yaklaşık 564 saniyede ölçüm gerçekleşmiştir.

Abstract
In this study, it is aimed to calculate the plant canopy projection area quickly by using image processing methods. Photographs from broccoli (Brassica oleraceae L.) plants were used for the experiments. Plants were separated from the ground using differences in color space by using the algorithm which created in MATLAB software. The actual area of the plant is calculated by comparing it with the known frame area. In the same photographs, areas were also calculated with planimeter and compared in terms of time and accuracy. A linear relationship, where R2=0.983, was found between areas calculated by image processing and areas measured by planimetry. With the image processing, the area was calculated at 0.002 seconds, while the planimetry measured approximately at 564 seconds.

Keywords
