Abstract
A method for use with a non-contact range finding and measurement system for generating a template guide representative of the surface of a observed object, and for utilizing the template guide to improve laser stripe signal to noise ratios and to compensate for corrupted regions in images of the observed object to improve measurement accuracy.
Claims8
A method for identifying images of laser stripes projected onto the surface of an object in a non-contact gauge measurement system, comprising:
- projecting one or more laser stripes onto a surface of an the object;
- obtaining an image of said projected laser stripes;
- generating a matched filter for each pixel in said image;
- filtering said image with said generated matched filter;
- and
- identifying the center of said projected laser stripes in said filtered image.
