An automatic method of inspecting the scaling accuracy of needle-type instrument gauges using a two-stage Hough transform technique is described. The system measures and verifies the relative accuracy of a gauge's response to a specified set of analog input signals. The method does not require that the gauge's position, orientation, or size be known a priori and the algorithm is very suitable for high-speed hardware implementation.
