BİLGİSAYARLI GÖRÜ SİSTEMLERİ İÇİN SİSTEM TASARIMI VE KONTROLÜ

Bilgisayarlı görme uygulamaları için aydınlatma ve sahne önemlidir. Nesnelerin özelliklerini belirlemek ve istenilen kalitede görüntü alabilmek, aydınlatma koşullarının olabildiğince sabit ve kontrollü olması ile sağlanır. Çalışmada bilgisayarlı görü uygulamalarında görüntünün dış koşullardan etkilenmemesi için bir ışık havuzu oluşturulmuştur. Sistemindeki LED aydınlatma armatürlerinin sürülmesi, ışık miktarının ve renk yelpazesinin bilgisayar ile kontrol edilmesi sağlanmıştır. Ayrıca iki farklı aydınlatma kaynağı kullanılarak mesafelere göre ışık havuzunun orta noktasına düşen aydınlık düzeyinin hem lüksmetre hem de görüntü işleme teknikleri ile belirlenmiştir.

System Design and Control for Computer Vision Systems

Lighting and environment are important for computer vision applications. It is necessary to determine the properties of the objects and to get the desired quality images. So as to be provided with constant and controlled lighting conditions. In the study, a pool of light was created so that the image was not affected by external conditions in computer vision applications. LED lighting fixtures driver, the amount of light and the color spectrum provided to control the computer in the system. In addition, two different lighting sources were used, and according to the distance of the center of the light pool of the light level was determined by both the luxury meter and the image processing techniques.
