PanelScan Integration Guide The remainder of the settings on the Vision Setup tab are for PanelScan Wide, which uses two cameras. Camera 1 on Top; Camera 2 on Top – For PanelScan Wide, two cameras are used side-by-side. They are mounted so that there is a 1” overlap in what each one captures. If a symbol appears in this middle ground, you can choose which camera will view this overlap area. For example, if a symbol is cut in half when viewed with Camera 1, Camera 2 can be selected as the camera “on top” such that it has a full view of the symbol. Camera 2 Overlap (Pixels) – The PanelScan user interface attempts to stitch the images from Camera 1 and Camera 2 into a single image.
You can choose which camera is on top and is used for the overlap area. It is necessary, however, to determine the amount of overlap in pixels to achieve an image that is as seamless as possible. When this value is set to 0 , the images from the two cameras are simply placed side-by-side. To determine the amount of overlap, it is useful to find a single feature on the panel that appears in the image from each camera. The pixel location for both instances of this feature can then be determined and the overlap amount can be calculated. To do this, set Camera 2 Overlap (Pixels) to 0 . Run a panel. Right-click the image and save it to disk.
Open the image in any image viewing or editing program that provides X and Y cursor values. Find a feature that is duplicated in both images. Find the pixel coordinates of each instance. Compute the x offset. In the example below, the number 6 appears in both the Camera 1 view on the left and the Camera 2 view on the right. Using the cursor, you can find pixel coordinates of an exact point – the center of the hole in the number 6, for example. Record the X and Y cursor values for this point in both images. In the example below, Camera 1 shows the number 6 at 5945,2141 , and Camera 2 shows it at 6556,2204 . Compute the X coordinate value and enter it as the Camera 2 Overlap.
In this example, the difference between 5945 and 6556 = 611 pixels . 28 Copyright © 2019 Omron Microscan Systems, Inc.
