Patent ID: 7725290

Claim:
A contour measuring method for measuring aspects of objects comprising the steps: (1) providing a measuring device comprising: a first contour measuring probe comprising a first tip extension being slidable in a first direction, at least one hollow tube for driving the first tip extension, and a first displacement sensor used to sense a displacement of the tip extension; a second contour measuring probe comprising a second tip extension being slidable in the first direction, at least one hollow tube for driving the second tip extension, and a second displacement sensor used to sense a displacement of the second tip extension; and a processor electrically connected to the first displacement sensor and the second displacement sensor respectively; (2) driving the first tip extension to contact a first surface of an object by the at least one hollow tube of the first contour measuring probe, and driving the second tip extension to contact a second surface of the object opposite to the first surface by the at least one hollow tube of the second contour measuring probe; (3) driving the first tip extension to move and maintain contact with the first surface of the object, and driving the second tip extension to move and maintain contact with the second surface of the object, while the first displacement sensor sending the displacement information of the first tip extension to the processor, and the second displacement sensor sending the displacement information of the second tip extension to the processor; (4) computing a cross-section of the object by the processor according to the displacement information on the first tip extension and the second tip extension; and (5) repeating the step (3) and (4), the processor computing a plurality of cross-sections of the object, the cross-sections compiled to obtain aspects of object.
