Workpiece positioning correction method, correction device, correction system and storage medium

The invention discloses a workpiece positioning correction method, a correction device, a correction system and a computer readable storage medium. The workpiece positioning correction method comprises the following steps: acquiring workpiece measurement data and workpiece model data of a to-be-positioned workpiece; determining a target function for performing positioning optimization on the workpiece to be positioned according to the workpiece measurement data and the workpiece model data; determining a search space for performing positioning optimization on the to-be-positioned workpiece according to the size of the to-be-positioned workpiece; and in the search space, correcting the workpiece model data based on a simulated annealing-particle swarm optimization algorithm, and minimizing the target function to determine workpiece positioning data. Therefore, the device is not influenced by the material of the workpiece to be positioned, is simple to operate, is high in correction speed, and can effectively improve the machining efficiency of the workpiece and reduce the machining error.
