ABSTRACT:
A system and method for measuring a curve of an object includes aligning the ideal curve and the real point-cloud of the object, and defining a plurality of tolerance ranges for an area of a real curve of the object having a tolerance in a predetermined range. The method further includes determining a closest ideal point on the ideal curve corresponding to each real point in the real point-cloud, and assigning a serial number to each real point in the real point-cloud according to a sequence of the closest ideal points on the ideal curve. Furthermore, the method includes generating the real curve by connecting every two real points in the real point-cloud according to the serial number, and assigning a color to each line-segment according to the tolerance range in which two closest distances corresponding to two end-points of each line-segment fall.
