Abstract:
1. A system for calibrating an accessor comprising: at least one calibration sensor, the calibration sensor operable to emit energy, and the calibration sensor further operable to detect reflection of the emitted energy; an output device connected to the calibration sensor for outputting a sensing signal responsive to the emitted energy and detected reflection from the calibration sensor; and a library controller, the library controller configured to construct a pixel map based on the output sensing signal, the pixel map based on the detection of reflection of the emitted energy wherein the sensing signal is in a digital form as an indication of a non-reflective condition in response to the calibration sensor emitting energy without detecting a reflection of the emitted energy and as an indication of a reflective condition in response to the calibration sensor emitting energy and detecting a reflection of the emitted energy.
