A computer implemented method for augmenting a display image includes receiving image data, the image data including data representing one or more objects, and at least a first marker and a second marker. The method includes receiving a first confidence level for the first marker and a second confidence level for the second marker. The method includes determining a selected marker from the first marker and the second marker. The selected marker is determined according to a highest confidence level of the first confidence level and the second confidence level. The method includes determining a transformation and a positional offset for the selected marker. The method includes generating overlaid display data for the one or more objects in the image data, the one or more objects determined in accordance with the transformation and the positional offset.
