Patent ID: 7654008

Claim:
A contour measuring method for measuring aspects of objects comprising the steps: (1) providing a contour measuring probe comprising a tip extension, a displacement sensor, and a processor connected to the displacement sensor, the tip extension being slidable in a first direction, and the displacement sensor used to sense a displacement of the tip extension, and the tip extension always contacting with a surface of the object; (2) driving the tip extension to move and contact with the surface of the object at a first predetermined point, and recording a coordinate of the first predetermined point in the processor; (3) driving one of the tip extension and the object to move, thus, the tip extension contacts the surface of the object at a second predetermined point, the displacement sensor sensing a displacement of the tip extension along the first direction and sending the displacement to the processor, and the processor recording a coordinate of the second predetermined point; and (4) repeating the step (3), the processor recording a series of measured coordinates of points on the surface of the object.
