VCXG kameralar için sekansör programlama – Her tetik sinyali ile ROI’yi hareket ettirme

Yazılım örneği Baumer GAPI v2.9.0

Bu örnek, hareketli nesnenin önemli detaylarını yakalamak için ROI’yi (İlgi Alanı) tam kare üzerinde önceden tanımlanmış konumlara taşımak amacıyla sekansörü nasıl kullanacağınızı açıklar. Sekansörün her adımı, harici bir sinyal aracılığıyla tetiklenir. Bu, yapılandırmayı tek bir yerde kapsar, böylece yalnızca görüntü analiz görevlerinizi gerçekleştirmek için gereken verileri aktarır ve işlersiniz.

Sekansör ile neler yapılabileceği hakkında daha fazla ayrıntı öğrenmek isterseniz, kavramların ve özelliklerin çok daha ayrıntılı olarak açıklandığı aşağıdaki uygulama notlarına başvurabilirsiniz.

Şekil, açıklanan sıranın sonucunda elde edilen görüntüleri göstermektedir. ROI’nin görüntülenen alan üzerinde hareket ettirilmesiyle, şişe kamera içinde sanal olarak kesilmiş gibi görünür.
