description The invention provides a measurement error compensation method and device for a dynamic error of a three-coordinate measuring machine, and the method comprises the steps: inputting an obtained first geometric error related to a moving bridge in a specified three-coordinate measuring machine and a pitch angle generated by the moving bridge during accelerated motion into a moving bridge error compensation model; obtaining a first error compensation value for compensating a measurement error caused by the moving bridge to the initial measurement value, and inputting a switch displacement error when a contact-type measuring head in a specified three-coordinate measuring machine is in contact with a workpiece and a flexural deflection error when the contact-type measuring head is in contact with the workpiece into a measuring head error compensation model; and obtaining a second error compensation value for compensating a measurement error caused by the contact-type measuring head to the initial measurement value,
