Target region
Definition of target region
The positioning mark (hole or reflector) is typically placed in the center of the camera
image and defined as the target region during alignment and rack fine positioning of
the device. The target region then corresponds to the area around the center point
of the image. If necessary, the target region can be moved into another area of the
image using the SOPASair operating software. During operation, the device detects the
current location of the positioning mark. Depending on the selected evaluation mode,
the device transfers to the controller the difference between this location and the target
region or center point of the image. Using the information provided by the device, the
control initiates rack fine positioning of the automated storage and retrieval system. If
the positioning mark is located in the target region, goods can be stored in or retrieved
from the rack. If the positioning mark is outside the target region, the relative position
in relation to the target region is displayed using ambient sectors.
