# Alignment References
|
|
|
|
The alignment references are used in every round to re-align the taken image to the reference coordinates.
|
|
Two alignment structures must be defined and the taken image then in each round is shifted and rotated according to their position
|
|
with the target to be in exactly the same position as the reference image.
|
|
|
|
!!! Note
|
|
The alignment structures needs to be unique and have a good contrast.
|
|
It is advised to have them as far apart as possible.
|
|
|
|
## Precondition
|
|
|
|
Please make sure to have setup your camera properly and taken a good [Reference Image](Reference-Image.md).
|
|
|
|
## Define two Reference Images
|
|
|
|
{: style="width:500px"}
|
|
|
|
You can switch between this two marks with `(1)`.
|
|
|
|
Then define the reference area in the image by either directly drag and drop with the mouse or use the input boxes below.
|
|
To apply the currently marked image part you need to push `"Update Reference" (2)`.
|
|
|
|
In some cases it might be useful to use a reference with a higher contrast. This can be achieved by pushing `Enhance Contrast" (3)`.
|
|
The result will be calculated on the ESP32 - so be a bit patient, before you see it active.
|
|
|
|
To save push `"Save to config.ini" (4)`.
|
|
|
|
!!! Note
|
|
A reboot is not required at this point of time.
|
|
|
|
As next you should define the [Digit and Analog ROIs](ROI-Configuration.md).
