【Abstract】 A new method was presented in this paper, which can measure the shoelast’ s shape successively. We use a sensor whose shape is just like a plate to measure the shoelast’ s shape by touching with it, and the center of the sensor was saved as the original data. An algorithm was developed to convert the original data into the real data we wanted. The surface of the shoelast character in disengagement curve is made of irregular curves. We programmed to process these discrete points of the shoelast surface according to the precision requirement. Then, OpenGL skill was used to display the model of the shoelast in the computer.更多还原
