Abstract

The invention discloses a system and method for measuring a workpiece. The system comprises a laser displacement sensor, a motion mechanism, a controller and an upper computer system, wherein the motion mechanism is used for driving the laser displacement sensor to move under the control of the controller; the laser displacement sensor is used for measuring under the control of the controller and sending the acquired measurement data to the upper computer system; the controller is used for receiving an input instruction, confirming a to-be-measured position on the workpiece according to the instruction, controlling the motion mechanism to drive the laser displacement sensor to move according to the position and controlling the laser displacement sensor to measure the position of the workpiece; and the upper computer system is used for confirming a data processing rule corresponding to a measurement item selected in advance, utilizing the confirmed data processing rule to process the measurement data collected by the laser displacement sensor and acquiring a measurement result. According to the invention, the invalid measurement data can be prevented from being collected, and the measurement cost can be lowered.

Description

technical field [0001] The present invention relates to the field of measurement, and in particular, to a workpiece measurement system and method. Background technique [0002] Optical sensors are instruments that measure based on optical principles. This type of sensor has many advantages, such as non-contact and non-destructive measurement, almost uninterrupted measurement, high-speed transmission, telemetry, remote control, and real-time processing. advantage. [0003] Optical sensors include many types. Among them, the laser displacement sensor based on the laser triangulation method is a kind of laser displacement sensor that uses laser light as a light source, CMOS (Complementary Metal Oxide Semiconductor, Complementary Metal Oxide Semiconductor) or CCD (Charge-coupled Device, charge Coupling element) sensor as a precision measuring instrument for the receiver. This kind of sensor can accurately measure the position, displacement and other changes of the measured obj...
