Abstract: A measurement system includes a camera and a processor. The camera is configured to capture a measurement card image of a measurement card, and the measurement card image includes a number of feature pattern images. The processor is electrically connected to the camera and configured for analyzing the feature pattern images to obtain a feature point coordinate of a feature point of each feature pattern image, and inputting the feature point coordinates into a conversion matrix to obtain a tip coordinate of a tip of the measurement card.

Abstract: An electromagnetic shielding film for a cable, which relates to the field of wire manufacturing, for use in resolving the problem of easiness of break of the existing electromagnetic shielding film and the great consumption of time and power in the preparation process. The electromagnetic shielding film comprises a first metal layer (11,21,31,41), a conductive layer (12,22,32,42), and a protective film (13,23,33,43). The first metal layer covers the outer part of a conductor of a cable, and is used for shielding electromagnetic interference and is used as a medium. The conductive layer is disposed on the first metal layer, and is used for shielding electromagnetic interference, and the conductive layer comprises a curing agent, metal particles and polyurethane for carrying the metal particles. The protective film is disposed on the conductive layer and protects the electromagnetic shielding film.
