1. An automated data reading system comprising:

  • a data reader configured to identify objects as they pass through one or more read zones of the data reader;

    a transport mechanism to transport the objects placed thereon through one or more read zones of the data reader, the transport mechanism having a top surface on which the objects are placed and transported, the top surface defining a transport plane, wherein the transport mechanism transports the objects in a scanning direction; and

    an object measurement system to measure dimensions of objects that are transported by the transport mechanism through the data reader, the object measurement system comprising;

    a light plane generator disposed above the transport mechanism and operable to project a light plane vertically downward toward the transport mechanism, the light plane projected perpendicular to the transport plane and to the scanning direction, wherein the light plane produces a light stripe where the light plane strikes an object;

    a camera disposed above the transport mechanism and offset from the light plane generator, the camera comprising an imager and a lens and having a field of view (FOV) directed downward toward the transport mechanism and at an angle to the light plane, the camera configured to capture image data of an object as the object passes through the light plane,wherein a position of the light stripe within the image data is used to calculate a measurement of one or more dimensions of the object.
