Non-contact deviation measurement system

摘要

A non-contacting deviation measurement system projects a first line and a second line upon a surface of an object. The projections of the first line and second line are arranged to overlap at an intersection line oriented at a nominal location such that when the surface is oriented at the nominal location, the intersection line appears on the surface. As the location of the surface deviates from the nominal location, the first line and second line as projected upon the surface move away from one another. The distance between the lines may be used to calculate the deviation from the nominal location. The deviation calculated may be compared to a predetermined maximum allowable deviation.

1. A deviation measuring system comprising:
a first projector projecting a first line and a second projector projecting a second line, the first line overlapping the second line at an intersection line, the intersection line oriented at a nominal location; an optical sensor positioned to capture an image of the projections of the first line and the second line upon a surface of an object; and a processor executing an analysis software to analyze the captured image, the processor calculating the deviation between a location of the surface and the nominal location.
