Vision and Queue Loading

By default, vision images are acquired for all parts running on the same feeder. There is also a mechanism to acquire the image for only the Active Part (this will be discussed in the next section). Each part uses its specific lighting requirements (front/backlight, mobile camera, user processes vision using the PF_Vision callback etc….).

After all the Part Vision Sequences have run, all of the queues are loaded with the vision results.

TIP

---

For added efficiency the CameraBrightness and CameraContrast can be set the same for all part vision sequences. The vision sequence for the first part in the PF_Start list would have the RuntimeAcquire property set to Stationary. The remaining part vision sequences using the same feeder would have RuntimeAcquire set to None., This eliminates the time for additional grabs. This method assumes that all parts can be found using the same lighting conditions.
