Select Image Concepts

Use the Select Image step to switch to a previously acquired image for processing. For example, if you insert two acquisition steps to sequentially acquire two consecutive images from different cameras, the inspection steps that follow process only the second image. However, you can insert a Select Image step after the inspection steps to select the first image for processing. Inspection steps that follow the Select Image step process the first image. You can then make a decision using the Calculator step or Logic Calculator step based on measurements from the two images.

You can also use the Select Image step to apply different processing algorithms to the same image. If you insert a Vision Assistant step that modifies an image, you can use a Select Image step to retrieve the original image and apply another processing algorithm.
