Attaching and Detaching markers

If the connector point (above the marker) is in the connector area (area below marker) for x frames (5?10?) the two markers will be linked. This is regardless of whether they are subsequently moved.

If a marker is removed from the board for y frames (large enough that in moving markers, blocking the camera, it wouldn't be removed). If a link wants to be broken the two markers could be placed in a detachment area for z frames (2/3) or another method could be to rotate both markers so that they face the wrong way towards each other.

For this method to work I need to know the angle (which way up it is. Where the top and bottom is), the location and even possibly the size of the marker.
