When you have multiple similar targets on the screen that look alike, the default image analysis (Objective) may not work well. Setting a threshold too high of nearly 1 is also not recommended. Because your target may get a score below your threshold and return fails.
So, we recommend you use an anchor to cooperate with Objective to handle the multiple similar targets issue. This anchor is called Objective Anchor. It could be used when there are multiple similar targets on the screen, and there is an object whose relative position to the target image is known and unlikely to change. You could choose that object as an Anchor for your desired target. Objective Anchor is used to facilitate accurate identification for that case.
Below are examples of when you select a target without and with an anchor.
An Objective without Anchor:
We selected the target only using the Objective.
Preview without anchor:
The preview results show that the three Excel icons on the screen are selected as targets because they are all the same.
Objective + Anchor:
Then, we selected the target using the Objective and then use the Objective Anchor to select the desired anchor for the target.
Preview with anchor:
Theresult in the preview now shows only one Excel icon is selected as a target after we added an anchor.
