[0002] With the development of flexible manufacturing technology, flexible graphic layers have also begun to be used in engineering. The flexible graphic layer is to plate a layer of metal on the surface of the flexible substrate, and then etch a pattern of a certain size and shape. However, due to the processing range of the manufacturing equipment, large-sized flexible graphic layers cannot be processed as a whole, and usually splicing is selected. In this way, the contour accuracy of a single flexible graphic layer is required to be high.

[0003] When measuring the contour accuracy of this flexible graphic layer, the traditional contact measurement method, such as the machine tool dial indicator and three-coordinate contact measurement method, is limited by the ball head diameter and cannot measure parts with a thickness greater than 1mm. The traditional non-contact measurement method, when measured with a two-dimensional device, has high equipment use costs, the parts are encapsulated in a curled state, and the parts need to be flattened and fixed. At the same time, the workbench size is required to be large enough, and the contour needs to be sampled and fitted during the process. There are many data points collected, the data processing process is complicated, and the measurement results are not intuitive. Therefore, it is necessary to carry out research on the measurement method of the contour of the flexible graphic layer. For this purpose, a non-contact measurement method for the contour of the flexible graphic layer is proposed to solve the existing problems. Summary of the invention
