Trigger orchestration

When an input source receives a single shot trigger, it waits for a visual trigger before it starts to inspect an image.

Enabling trigger orchestration

When an external system is unable to send a single shot trigger at the same time as an object appears on an inspection camera, you can configure trigger orchestration. Then, when an inspection receives a single shot trigger, the visual trigger evaluates images by using the frame rate that is configured.

For example, an inspection that uses a camera as an input source is inspecting a part (object) on an assembly line. A bar code reader scans the part number on the object before the object appears on the camera. When trigger orchestration is enabled, the bar code is scanned and the inspection waits until a visual trigger indicates that the object is in front of the camera.

Note: You can enable trigger orchestration when single shot trigger or visual trigger is enabled in an inspection configuration.

Trigger orchestration is enabled

When trigger orchestration is enabled, the following process is completed:

  1. The inspection starts in waiting mode. Any received images are discarded.
  2. The inspection receives a single shot trigger. The visual trigger processes subsequent images.
  3. The visual trigger evaluates images by using the frame rate that is configured in the trigger orchestration.
  4. An image meets the conditions of the visual trigger and qualifies for further processing. Images that do not meet the condition of the visual trigger are discarded.
  5. The inspection switches back to waiting mode until another single shot trigger is received.
  6. The inspection rules are evaluated on the qualified image.
  7. The qualified image is persisted on the Maximo® Visual Inspection Edge server and is then sent to the Maximo Visual Inspection server.

Trigger orchestration is not enabled

When trigger orchestration is not enabled, the following process is completed:

  1. The inspection receives a single shot trigger and processes a single image.
  2. The visual trigger analyzes the images to see whether they match the specified conditions.
Note: If the image does not meet the trigger conditions, the visual trigger does not process the image further and does not save or send the image to the Maximo Visual Inspection server.
