Abstract:
1. A method for determining a characteristic of an object, comprising: providing relative motion between the object and a two-dimensional field of view, the object comprising a set of visible features, the set of visible features containing at least one visible feature; inputting an encoding signal responsive to the relative motion, from which can be obtained at desired times a corresponding encoder count indicating a location of the object relative to when the object passes a fixed point in the field of view; capturing a plurality of active frames displayed by a graphical user interface, each frame of the plurality of active frames comprising an image of the field of view when the object passes through the field of view; obtaining a plurality of capture counts corresponding to the plurality of active frames, each capture count of the plurality of capture counts being responsive to the encoder count corresponding to a time at which the corresponding active frame was captured; computing, responsive to an analysis of the plurality of active frames, a plurality of location values, each location value of the plurality of location values responsive to a position in the field of view of a visible feature of the set of visible features in an associated active frame; and determining the characteristic of the object using the plurality of location values and the plurality of capture counts such that an output signal sent to a downstream actuator can be synchronized to the location of the object.
