Patent ID: 7257248

Claim:
A method for non-contact measurement of a complex part, the method comprising: acquiring an image of the complex part including imposed laser lines on the complex part using at least one imaging device; determining a span of interest of the complex part, the span of interest being representative of at least a portion of the complex part and which contains information related to a plurality of dimensions of a surface of the complex part; and extracting information corresponding to the laser lines from the span of interest, including scanning a plurality of rows in the span of interest, wherein each of the plurality of rows comprises a plurality of pixels, detecting a plurality of peaks by continuously comparing an intensity value of each pixel with an intensity value of an adjacent pixel, generating a rise intensity value point, a maximum intensity value point and a fall intensity value point for each of the plurality of peaks and balancing the rise intensity value point and the fall intensity value point to generate a foot intensity value point for each of the plurality of peaks, and further extracting a plurality of unique points from the information corresponding to the laser lines using the rise intensity value point, the maximum intensity value point, the fall intensity value point and the foot intensity value point for each of the plurality of peaks, the plurality of unique points representing the plurality of dimensions of the surface.
