The invention discloses a measurement method of rebounding amount after plate stamping forming and belongs to the technical field of stamping forming rebounding. The technical scheme is as follows: the die surface of a to-be-stamped part and a rebounded part are scanned through a 3D laser scanner, three-dimensional space coordinate point clouds of a die and a part after stamping forming and rebounding are obtained and are compared in software, and thus the rebounding amount of the part in any position in any direction can be obtained. The measurement method is applied to parts obtained throughdie stamping and is not limited by materials, surface qualities, shapes, sizes and the like, extra machining of a checking tool is not needed, the measurement accuracy is high, the cost is low, operation is simple, and measurement is convenient and fast.
