VCXG kameralar için sekansör programlama – Tek bir gelen tetikleme ile birden fazla çekim
Yazılım örneği Baumer GAPI v2.9.0
Bu örnek, tek bir tetikleme sinyalinden 3 görüntü elde etmek için bir sekansörün nasıl ayarlanacağını açıklar. Bunu başarmak için, pozlamaları tetiklemek üzere bir sekansör sayacı kullanılır.
Sekansör ile neler yapılabileceği hakkında daha fazla ayrıntı öğrenmek isterseniz, kavramların ve özelliklerin çok daha ayrıntılı olarak açıklandığı aşağıdaki uygulama notlarına başvurabilirsiniz.
Sekansör kullanımı, neyin ne zaman gerçekleşmesi gerektiğini görselleştirmek için bazı planlamalar gerektirebilir. Örneğimizde, işlem oldukça basittir:
- İlk görüntü, “Line 0” girişinden gelen donanım tetikleyici ile tetiklenir ve bu aynı zamanda sekansörün başlamasını da tetikler.
- Sekansör seti “Set0”, ikinci görüntüyü yapılandırır ve tetikler.
- Sekansör seti “Set1”, üçüncü görüntüyü yapılandırır ve tetikler.
