ABSTRACT:
The disclosed apparatus determines the parameters, such as size, shape, and position, of figures on a surface. It includes a camera means generating a video signal. A table assembly adjusts the position of the camera and surface on the table with respect to each other as specified by position signals. Control circuitry generates the position signals so as to bring at least a portion of a figure into the camera's field of view. The video signal generated when this portion of a figure is in view is used by processing circuitry to determine the figure's parameters.
In one embodiment, the expected parameter values for a figure are retrieved from storage circuitry and compared against the parameter values as determined by the processing circuitry. If the parameter values are out of range, an error signal is generated. Error data may be recorded or transmitted to an external device for statistical analysis.
