Procedure_Selection_of_Anchors_based_on_Error_on_Distance |
Procedure Min-Max If there are larger than expected large circles for the used hardware: delete them |
Procedure Ignoring_Circles Delete the typical circles containing at least 5 others if there are no typical circles contained by at least 5 others If there are typical circles contained by at least five others delete them. |
Procedure Maximum_Likelihood Group the anchors based on distance Are there small distance circles contained by other small distance circles of other group members? |
If yes: new typical circle radius all members = geometric average of m measured distances new_Error_on_Distance = (Error_on_Distance of member) /sqrt (# remaining typical circles -1) adapt small and large circles according to new_Error_on_Distance continue If no: continue |
