Abstract Technologically, the measurement is that four edge positions are measured by means of double-lens imaging and used for calculation the 2D coordinates and width of measured object, with the two edges being irradiated by an active light source. Unaffected by the oscillation, inclination and temperature variation of measured object, the said method can measure object in different temperature. The measurement equipment may be calibrated with a cold object set in measured area fast.
