Aimed at the difficulties of error elimination of horizontal direction dynamic accuracy measurement to press,a trigger measurement was proposed based on composite principle of displace-ment sensor and photoelectric sensor.The measurement as well as the existed defects of soft-trigger-and hard-trigger were discussed,and an improved soft-trigger measurement was proposed.The feasi-bility of this measurement was validated by experiments,and the announcements in experiments were illustrated.Regarding to the larger noise of initial displacement signals in trigger measurement,two methods of noise reduction were provided using the filtering and themultiple-point averaging,and the results were compared.
